00:05 today we will talk about all factions no factor information processing. So we

00:12 touched upon. And when we talked COVID-19 at the very beginning of the

00:18 . And we said that there is 19 infections. And there's ways in

00:24 covid can enter into the brain. so one of the ways that covid

00:28 enter into the brain is through the epithelium. And that's because there are

00:34 cells and that helium to which the can find and interact with. And

00:41 because there's physically administrations and describe reform physical administrations in this place. So

00:49 allows for an infection to enter through uh cooper form playing a little factory

00:56 helium. You look at the olfactory may have done rides of the olfactory

01:03 cells and then you have this silly factory yourself for cells you have the

01:08 and then you have the axons and accents coming in will form cranial nerve

01:14 or olfactory nerve that will project into olfactory bulb where it will sign ups

01:19 the secondary order of factory neurons surrounding cells, backward receptor cells you have

01:28 cells and you have supporting cells and look into the structure a little bit

01:33 again when we talk about covid 19 the very end of this semester.

01:38 how do we generate a sense of ? What is smell smell is odor

01:45 that are in the air and those molecules entry into our nasal cavity.

01:50 we smell them. And the process which this happens is that deodorant and

01:57 nucleus bind directly to one of the receptor molecules located in the membranes of

02:05 A. So this is a receptor . This is an odorant molecule that's

02:10 bind to that receptor. It's ju couple signaling will activate it in a

02:15 cyclist. It will increase cyclic GMP so that's I click A and

02:22 Is going to keep the mixed cat channel open. It's mixed cat ion

02:28 because the channel is permissible to vote and sodium. However, most of

02:34 deep polarization is not really gonna come the flux of sodium and calcium into

02:39 psyllium. And rather the increase in concentrations here will result in regulation of

02:47 chloride channel. So this is something haven't seen before. This is an

02:51 gated ion channel. So in this calcium two plus is regulating the opening

02:58 chloride channel, chloride channel opening and leaving the south negative charges leaving the

03:06 will contribute to the greatest amount of deep polarization in the membrane that you're

03:12 in these cells. So once again have the cilia. Yeah the den

03:17 whether receptive potential is generated so much generate action potentials of those action

03:24 Factory term will be communicated to the evolved. What's interesting is within the

03:43 epithelium. You have a variety of cells. And what distinguishes these different

03:52 cells is that they express a single receptor protium, it's a specific party

03:59 that they express in their memory. that Protium for example if the south

04:05 one some type of program it's shown is green, blue, orange

04:12 dark green, dark blue and so . Over here, each color represents

04:16 fact that each one of those all expresses a different receptor protein. Does

04:22 mean that those cells green sauce are going to be responsive to one

04:28 No, they will be responsive, too many odors. But how they

04:33 to that motor is going to differ when owners activate the factory and the

04:39 they don't activate just one side back cells. And these cells are randomly

04:44 throughout the olfactory epithelium. And so you expose the nose to sell smell

04:50 citrus you will see that green cells the pro team receptor protein that's very

04:56 binds to the odorant molecules that represents . This the Turpin's or the small

05:02 and citrus. But the blue sauce just produce a few actual potential.

05:06 the red sauce will be silent. the other hand, the floral cell

05:11 induce a different pattern in the green of actual potential fire. It will

05:17 the blue sauce the greater extent and activate bread cells. So this would

05:21 a floral surmount. A peppermint smell activate all three types of cells but

05:26 blue cells will be activated just to very small extent and almond as you

05:31 see almond descent activated green cells. this is just an example of three

05:36 of cells and four types of odors are presented to these three types of

05:41 . Within reality you have hundreds of different types of cells and you have

05:48 of different voters. That we are by our environments. That information from

05:56 olfactory nerve will travel through the crew plate and synapse onto the secondary order

06:04 neurons which are found in the olfactory . And where the synapse on this

06:09 where you have a specialized location called . The structure of luminaria list is

06:17 unlike different receptor cells that are randomly throughout the helium. In the culinary

06:24 list, all of the green cells converge onto single memorial. So

06:29 Valueless to process information from all of green styles from all of the cells

06:34 just have that receptor protein and That will be the materialistic processes from

06:40 cells. Another receptor protein odors and processes Blue south. So here you

06:48 a map now you have a map activity. So you have a structure

06:53 distributed cells and at least randomly distributed converge onto the glimmering analysts and you

07:00 the map of the odors that could represented that. So if you activate

07:05 green red and blue cells to a extent it will also activate the glue

07:11 a list of the certain extent. Oder said with strong for the green

07:16 like citrus will activate the green blue a list of the very strong

07:20 So all of the circuits and cells the glove, aerialists processing the citrus

07:25 be very active during that smile, they will not be as active.

07:29 red sauce will not be active at during the citrus smell. Now from

07:36 olfactory bulb, the secondary order neurons project onto the whole factory do brickell

07:44 all factory biblical. This is now often tracked, okay. And the

07:51 track goes into the olfactory recall. there it goes into the medial dorsal

07:56 of the thalamus and prepare goes into orbitofrontal cortex. But as if you

08:02 there is a division of these fibers , bell factor cortex and related temporal

08:07 structures. So it is almost like emergence of this olfactory signal. One

08:13 it is being processed through thalamus to cortex which we would say more,

08:17 like a conscious contemplated processing of the Perception and the other one is primitive

08:26 of neural circuits directly from the factory . Now this is an experiment in

08:36 we're looking at the surface of the and this is a rodent brain.

08:41 if you remember rodents have these massive involves because their life and their

08:49 they're dependent on smelling things to find and whisking around. So we looked

08:54 the somatosensory system. Now if you the skull and you shave the skull

09:00 the rides to very thin so where becomes a translucent window you can actually

09:05 or factor involved. And when we about imaging techniques, we talked about

09:11 imaging techniques. We talked about M. R. I. We

09:15 about pet scans and we said that imaging techniques image metabolism, the image

09:22 , blood flow and metabolism of But when we visualize activity experimentally in

09:30 neuroscience setting, we can have different . We already alluded to calcium sensitive

09:36 that dies. That shows fluctuations of . We talked about that when we

09:40 about synaptic transmission and release of the where you saw the imaging study that

09:47 rises locally in the castle levels. in this case, what we're looking

09:52 is that this is the macroscopic view the factory boat. And we're using

09:59 diet that's sensitive to counsel. And it's also very meaningful to use the

10:04 for calcium because it's calcium dependent chloride that caused most of the deep polarization

10:10 these cells. So when we look the olfactory ball and the rat is

10:16 to high school prom bill. Uh Glades which is minty smell, minty

10:22 . This is the glamorous realist that active by minty smell another one and

10:27 third one. So it seems to this is the map of minty smell

10:32 the olfactory ball and this is the on the ride of the fruity

10:39 And now you can see the fruity will activate distinct luminaria light at different

10:43 mary right from what the DNT smell activated. So first of all you

10:48 this underlying structure and then you have activity that imaging and disciplinarian lives on

10:58 of that structure. And as you the activity to different smells, you

11:04 a functional map activity map for minty . The functional activity map for fruity

11:14 . You can get into even more . This is pining and citrusy.

11:20 alpha pining is a turkey. So lot of things that you smell odors

11:26 turkeys. Octonal alpha pining Jackson. there are shorter carbon length. These

11:33 organic chemistry molecules carbons 123456 carbon long , 12345678 carbon long molecule. Okay

11:46 can count 12345678 carbon long molecule. the life of the molecule is important

11:55 the shorter is the molecule, the number of carbons it has, the

11:59 volatile it is. These are the that spread very easily. These are

12:03 smiles on the perfume industry or in shampoos or soaps or candles will be

12:09 Top notes Russia is the bottom So this is the lab for alpha

12:15 anywhere you see the green mamba really and the cells activated. This is

12:21 map for the Pyrenees following. This the map in red for the citrus

12:27 . This isn't gonna piney smell and grass smell. And this is citrus

12:34 . Yes. Does the in Cairo that's still like the orientation of it

12:39 how it smells too? Like if D and something or else something,

12:46 you repeat the question? Like in adam? So I dont Adams that

12:49 like four different groups attached to the because yeah, of course the variations

12:55 structural variations of these molecules will determine different changes, smells. I'm not

13:03 though, if the are you talking as a university, I think it

13:07 slightly be a different smile too. in a different configuration trans versus says

13:13 or maybe strong versus weak, but quote me on that. I'll tell

13:19 we need to program this. Uh now when we talk about rodents is

13:26 thing, this is all factory This is really nice spouse. But

13:31 about human brain, does that mean have smell maps? Does that mean

13:35 have a map for flowers map for and grapes in the bathroom. We

13:44 . And this map is not limited a factory ball. The connections have

13:49 cortical areas. So this is a ins and this is inhaling flour,

13:55 ins and this is a minty This is a rose map. This

13:59 a banana map. This is a map. And if you look inside

14:03 brain, functional imaging of the brain the person is smiling something, it's

14:08 just a factory bald, it's a load, it's a frontal load.

14:13 psycho physiological effect. It's actually physiological . A lot of times we think

14:20 when we talk about aromatherapy, it's psychological, in what sense? If

14:27 look at what I'm telling you it's the physiology of the odorant molecules

14:33 to the cilia changing activity in your and establishing a certain math and that

14:41 influence how you feel and how you . You smell bathroom and it's

14:45 I don't want to be there, going to go away. You smell

14:48 who's smelling really pleasant, you're going be attractive and you're gonna follow,

14:52 know, so or or or things gonna want to eat because it smells

14:57 good or it's gonna repulsive because it's not. So there's a map for

15:03 of the smiles inside your head. there are also renditions of these maps

15:11 artists, okay? And this is rendition of a map by kate mclean

15:22 what a turkey. So when you around and you're smelling things that smelling

15:26 odor molecules are smelling the start means of the large group of volatile and

15:32 hydrocarbons found in essential oils of plants found affairs and citrus streets, they're

15:37 on a cyclic molecule having the formula 10 h 16 months of most of

15:43 are 10 carbon long chains. But not all bacteria produce a lot of

15:52 years and that's why the bathroom stinks they go to the bathroom. So

15:57 everywhere, everywhere smells and turbines and molecules are pretty much everywhere except for

16:03 know, yes. Things that are concrete. And then when we say

16:10 still has a smile, concrete still a smell. It was this

16:14 plastic still has a smell. I know what it is. Maybe synthetic

16:19 maybe not natural oder but it's And so this is the small maps

16:27 you have inside the brains. The is do we have small maps for

16:31 world that we live in? we do. We don't pay as

16:36 attention to them when we have all our senses attacks. So as humans

16:41 rely a lot of on sound and before we walk up and explore

16:46 For example when you come up close you start smiling things. But if

16:54 person is blind for example, their is different the way they perceive the

17:00 , the way they follow the cues the outside world are not visual

17:05 there's gonna be other cues and their are gonna tune in a lot more

17:10 the other senses. So tuning in sound, tuning into smiles. Samara

17:21 think about when you see a blind walking with their blind stick. It's

17:27 because they have special sound on the indicating that it's safe to cross and

17:34 things with an extension of your essentially touching everything. And then when

17:39 can come closely you actually are touching read it. So other animals for

17:47 , rely much more on the smell of the outside world. They don't

17:53 as good as the vision or hearing they have to rely on as a

17:58 of sensor and all factor information have smell things out. They can't see

18:02 they can smell from far away They'll go out for a hunt,

18:07 will not be, you know, , they'll be smiling something first.

18:13 and so this is really cool, is an artist kate Mclean and she

18:18 a map of the editor. So you're seeing the green, anywhere you're

18:27 these green dots, it's a concentration sea sand and beach spells. So

18:34 , you look at this, there's lot of beach from the side of

18:37 , there's a couple of smaller sandy , there's a big one over

18:42 there's a beach right here too. smells like beach in that town.

18:46 what she did is she walked around town and then everywhere you're seeing

18:51 So what do we have a lot in Edinburgh here, a lot of

18:57 . So there's a lot of blue and everywhere you see blue smells or

19:04 blue lines is where there's the beer and the blue where there's the highest

19:11 of markets, hotspots. So, then there is for example, an

19:18 is fish and chips shops, there's lot of them in Edinburgh to fish

19:23 chips is fried fish and chips are fries. So fish and chips.

19:29 anywhere you see that dark blue that's where you have fish and

19:35 So if you walked around the city she says, I smell like

19:38 it smells like beach, it's going . Well, it still smells a

19:42 bit like beach. Oh, it like a brewery. It smells

19:46 Like a bruise is stronger like a . Now you may, you may

19:52 that, okay, this is all and deadly. This is an artist

19:56 of the outside world of the spell . Now, imagine if this was

20:02 map that you could present a blind in braille. So instead of a

20:09 map, we just think about It's quite difficult. Many buildings,

20:16 crossroads. This gives you a general , I'm in the brewery smell area

20:25 actually you could use this as an tool to support your senses to where

20:31 are located. Ah if you can , the map that you will have

20:39 the braille of the city is only good as you can touch things and

20:43 around the salads, but this is really valuable and I don't think it's

20:49 utilized right now. So when we about different things in neuroscience during this

20:54 and tell that you guys are gonna and make this happen, you're gonna

20:59 questions. So the map of spouse the blind of the buildings of the

21:07 of their environments so that they know they're walking in a that smell and

21:13 smell is that location. It's this . Is that? So think about

21:21 . So the person who has answered should take about the different molecules,

21:26 structures the uh eyes unversity R. . D. All of these things

21:37 ? The orientation is dr Luca The doctors, Luca Turin is a

21:44 god he's a physicist and he is scientist then develops the most expensive perfumes

21:51 the world and he's written a book The Secret of Sound. And so

21:55 recommend for you this is a pleasure secret of sent if you want to

22:02 how somebody actually designs a product that certain smells and why that product would

22:11 over others. So he has a system that's based on science both on

22:17 and on physics smells that resonance that . They have their own frequencies of

22:26 the cilia that there are resonant frequencies smells and mixing them, gives them

22:33 best success in in in in in job which is being a perfume

22:42 So now there's something really interesting about and I already may have eluded that

22:50 there's you can send a note, doubt voice mail digitally. You can

23:00 the picture literally picture from your you can touch somebody over distance because

23:11 have a remote control surgeries that have but you cannot send smell turning

23:23 Yeah, perfume industry knows about that may have done this extensively for every

23:34 . Almost every magazine unless it's like or something like that or something

23:39 News will have tabs for perfumes and open that tab and you smell that's

23:48 only thing but that's in print and is physical. It's not it's

23:53 it's not digital. Now imagine you coming up with another thing for the

24:01 little device, little devices like a but instead of ink and having these

24:10 in colors, it has different odorant of the storage, these different codes

24:18 you saw green, red, and you have these odorant molecules.

24:23 now somebody send you a message on computer and that message is I'm sending

24:31 a bouquet of roses and you click your message on the email and the

24:39 that is sitting on the computer, releases the smell of roses. The

24:45 of odor molecules and turbulence that reproduces of rose, You know this is

24:55 future 22nd century maybe. But on very interesting way again people that are

25:03 senses this becomes very important. So it's a station rather than the personal

25:08 , maybe it's a station where people come and smell different things and learn

25:13 smelling different things digitally. Uh So now these shorter molecules are the

25:23 carbon molecules and in the perfume industry called Tavernas, they usually reveal themselves

25:30 seconds to minutes. The longer molecules notes that last sentence two hours and

25:37 longest bottom known molecules last hours to . So most of the high end

25:45 that are expensive are designed to contain full complement top part of the bottom

25:52 , Campbell's that are expensive. You , typically I don't know $20 up

25:57 candles. A lot of times they describe tom bottom nodes or hard nodes

26:04 they're designed and so that there's smells around. The early smells are very

26:11 , usually citrusy smells and the late are very woody and very animalistic.

26:17 woody like other would would like uh smell almost like sweat skunk which is

26:27 used as a base in the perfume . Have you have you ever heard

26:31 ambergris that comes from Wales? It's stinky kind of gooey and very potent

26:39 substances. So we as humans And dogs actually can smell only carbon molecules

26:49 a 16 carbon long, we cannot molecules that are longer. So we

26:55 talk about medical cannabinoids of medical cannabis cannabis is notorious for having a really

27:02 smile. So you know if somebody cannabis, I'm not saying it's marijuana

27:09 because it's actually the same thing. you know that somebody has candidates and

27:15 even tell my kids that if it then you know what it is,

27:20 it doesn't and some white powder, really don't know what it is.

27:26 know? So cannabis has really strong , it has a lot of Turpin's

27:34 that's what smells in cannabis. Cannabinoid or 22 carbons or longer, so

27:40 cannot smell them and the dogs cannot Canavan resigned. So when the dogs

27:46 by police and law enforcement were trained find Canada's marijuana, they used to

27:53 trained to find a certain turpentine and european is also in all happy all

28:02 and that therapy this in fact is in hops and it's also enclosed.

28:08 you were here when dogs were being and said like, oh, false

28:13 with his false positive hit, that the dog smelled something a therapy in

28:18 says it's cannabis because it's trained But guess what? It's actually

28:24 which is legal or it's closed, is also legal because the same Turpin's

28:30 turbines will be in cannabis, the lavender terminals will be cannabis. So

28:36 why right now, for example, are not even being trained to Chicago

28:42 smell um Canada is because it's it's many over, too much overlap would

28:49 . Too much overlap with other So typically when you go to the

28:55 and you want to pick out And let's say you're picking out of

29:01 , the first thing you're gonna do you're gonna look at it, this

29:03 looks good, then you're gonna pick and you're gonna inspect it visually.

29:09 it have any bruises on it? it you know, cut someplace,

29:13 know, maybe you're going to look the texture of it. And then

29:18 thing that you are very likely to is smell it Well. Yeah,

29:22 tap it. Do you smell? then if you get it really

29:27 now this is part of the routine good in senior grocery basket. You

29:34 through the same routine, you tap then you lift it up kind of

29:38 smile, you put it back and go for the next one. One

29:45 we've been trained that things that are things that are smelled, they're

29:51 they're alive, they're natural. A example is Fresh Dill versus dr

29:59 Fresh Dill. A branch of fresh can smell up the whole house like

30:04 dried dill, you can have a full of dried dill City. It's

30:08 because a lot of these volatile molecules the drying process for the herbs for

30:14 vegetables, they evaporate, they're no there where they destroyed by whatever processing

30:22 involved. So typically better. And the fresher the flower, the fresher

30:27 fruit and it's also warning about Europeans, I'm not saying that we're

30:33 to Turpin's, there's a lot of that we're allergic to most of pollen

30:37 the biggest algorithm that is out But when we smell cut grass,

30:42 know that there's going to be pollen that cut grass and we're not gonna

30:46 over there, we're gonna stay on side of the street because we may

30:49 allergic to cut grass. So it's warning sign to it's also an

30:58 So were you attracted to circum fruit vegetables Because of their smile. You're

31:03 to certain people because of their smile choosing a maid. Sometimes this might

31:09 one of the most powerful, most things that smell. And a lot

31:16 times it is non conscious. So not something you're thinking about. But

31:21 me, if you are the person you don't like her is smell.

31:25 difficult. Despite under Damian's Yeah, hope you like this smells perfectly

31:37 And we were trained. You we're trying to like smell our family

31:41 stuff. It's like so many memories with smiles and smiles are not just

31:46 passive. So aroma sacrificial theology, psycho. It changes your psyche

31:56 I'm gonna relax. Is it the effect? Maybe it is a placebo

32:02 . But if you ask the guys pharmacology department, placebo effect accounts for

32:08 of a change. So give me placebo effect. I'll relax. 30%

32:13 maximum with lavender, you know, physiology. Why? Because its brain

32:20 , it's brain maps it's activity. decision making. You go to sit

32:24 the table, you're going to visit , you're gonna purchase this product

32:30 A lot of it is for but a lot of it is for

32:36 . How do you expose people to to fruits and vegetables? You

32:41 there's a whole system behind it. studies of behaviors and habits and and

32:49 economics is another very interesting. So are what I see are emerging new

32:55 that are related to processing or factory , aroma psycho physiology, your economic

33:03 . It's also very much tied with and new economics in general is about

33:10 decision to click or not to That is the question because once you

33:19 they got you They got the they got your $20 credit card

33:27 Maybe your age. It's huge. may spend $200 for you to make

33:35 clinic, you know that you probably . But that's why when you go

33:40 social media or facebook, like why these ads for some pine nuts because

33:46 I searched for violence two days ago now it's nothing but finance for the

33:51 two weeks on my as what does mean? That means somebody is paying

33:58 to show me the pilot pads And that if they spend $5 showing these

34:04 $10 strongly these as and I'll go click the button then purchase it for

34:10 or $20. If they make a of me, it's called customer acquisition

34:16 in the business language. How much it cost you to acquire that customer

34:20 them to make a decision to How do you get to that

34:27 Brave? How do you use the of what you've learned about neuroscience,

34:32 sensory systems, circuit processing outside environment really improving the world in many different

34:42 or making better sale numbers. But so these are, these are always

34:50 interesting concepts but actually today's lecture is little bit shorter. I was gonna

34:57 about taste at some point, I gonna taste it this portion of the

35:02 but I'm gonna leave it pretty compact and since it's a cozy classroom

35:08 probably the clothes, the coziest we . It's like everybody gets bonus points

35:14 the classroom. Don't tell some people have a question. Yeah. I

35:23 wanted to ask um what makes the smells smells good and some bad.

35:28 it more like brain stuff? Where it actually smell maps in the nose

35:32 are making it smell good? It's , It's environment. You grew up

35:37 a lot of business, you during, during the early sensor

35:42 you know, I have to tell that when you have people come from

35:47 lands or when you go to far . the first thing you notice like

35:53 you get off on the bus and taxi restaurant, hotel, wow,

35:58 sauce smells different, you know, sometimes it's this strange smell. You

36:11 , Nigerians will complain about french body and french will complain about Nigerian body

36:20 . And Nigerians would love, you , Nigerian body. Oh and and

36:26 and it's a collection of things, also part of your local environment.

36:29 whatever you can seal, digest your seeps through the skin. You

36:36 it's what you carry around you. bet you, you know like this

36:43 Houston is so international, it's so because we have so many different things

36:49 we actually, if you're here for few years which you grew up

36:53 you are very multicultural. For the part you're having a Vietnamese coffee in

37:02 morning or boba tea versus regular You know, you're having a taco

37:09 lunch, you know, and then finishing an evening with with the beer

37:15 the burger joint. It's it's it's a mix of all of the

37:20 and if you were to make think this actually, what does the Houston

37:26 map looks like complicated. There's a of different places actually. So if

37:35 move closely walk closer towards where Pasadena and the ship channels a lot of

37:42 smiles, it will have, I feel like since we have so

37:47 road we would have a lot of smell. Not so much a lot

37:51 cars smell, but then the tender by you, there's a sewage

37:58 there's trees, there's parks and then think about food. You know,

38:06 water burger, you don't have to or or you know, you're

38:11 oh my God, this smells like asian food. And you know that

38:15 like, that's probably didn't bel air if I didn't have vision, but

38:20 relied on smell maps. You when I would start smelling dumplings and

38:25 like that, I would say, , this is probably, you

38:28 these great restaurants in bel air. why do we perceive them differently?

38:35 also Anatomy. Some people have better of smell something you can train yourself

38:44 like looking at things or writing noticing , smelling things to people that so

38:52 for example, there's so many years is one of the selling points for

38:57 too. But the real experts and that sell perfumes, well, a

39:04 of it is my brand because people perfumes. But if you go to

39:08 sophisticated stores, you know, there be more attention to to you as

39:17 individual and how you perceive smells and we're all a little bit different,

39:23 little different subset of this color proteins we expressed to and maybe ah some

39:32 us complement each other with that. it's the opposites to attract, you

39:39 , there's a whole science behind fair of things that we we that we

39:46 by but we don't perceive them starts . I mean do we smell things

39:54 the way that some people taste things ? Like the whole cilantro. Some

39:59 think that it tastes like soap and like a genetic thing. Is that

40:01 same thing with smell as well? . So it's probably something about the

40:07 of this receptor cells and the proteins because as you saw the smiles with

40:13 by activating themselves. So yeah, you're missing that red color with that

40:19 color with not smelling. So you but maybe you're missing that receptor podium

40:26 is red. And then it smells smells like soap and something else smells

40:31 . So to. Mm hmm. . Yeah. I have two

40:38 How can like smells trigger migraines And do you like migraines increased hyper sensitivity

40:45 smells. I don't know much about triggering migraines. But if that is

40:52 thing then I will have to look general migraines. And seizures sometimes can

40:58 triggered by strong sensory experiences. And is potentially one of them. But

41:05 know that bright lights can trigger migraines sound a lot of noise to trigger

41:11 to. And the earth is a strong smell. The potential to contribute

41:17 . Or maybe somehow got them to that somehow over activates your olfactory bulb

41:25 of your individual expression of these receptor . So, ah I don't have

41:34 very good answer to that. But it seems to me that it's just

41:39 strong sense of experience that can evoke and sometimes even seizure activity to pick

41:47 sound with strobe lights flashing strobe Alright, so we'll end the gear

41:56 little earlier today. And I will you guys know for sure when we

42:03 each other about the cliffs. This , come on sarah plus get your

42:14
