Thank you We sneak in and his you're shmoop du

00:04

jour brought to you by sensory stimuli like appearance odor

00:09

taste touch and hearing thie effects of which can increase

00:12

tenfold with the presence of a single cobbler there All

00:16

right the process by which the brain can turn sensory

00:19

stimuli from the outside world into electrical signals that it

00:23

can process is called what And here are potential answers

00:28

adaption had situation transected i was starting from the top

00:32

let's to find a sensory adaptation otherwise known as neural

00:36

adaptation This is when century receptors change their sensitivity to

00:41

a specific stimulus over time An example of this would

00:44

be that if a toddler happened to spit right in

00:47

your hand yeah initially you'll feel that sticky gross potentially

00:50

snotty spit right in your hand but after a few

00:54

seconds despite the spit still being there you'd stop really

00:57

feeling the spit as much as you did in the

00:59

first initial seconds So while you can think sensory adaptation

01:03

for saving you from prolonged lu gi suffering this is

01:07

not the answer we're looking for But seriously go wash

01:09

your hands that's just gross Similarly if that toddler screeched

01:13

as loudly as possible you'd probably react in one way

01:16

or another Rage tears a looky right back at him

01:20

on that show it's really up to you But if

01:22

he kept screeching over and over again you'd eventually stop

01:25

responding to it Well this is described a century have

01:28

pichu ation like you get in the habit of not

01:30

responding to it which in simpler terms is when an

01:32

organism learns to stop responding to a stimulus once it's

01:36

deemed irrelevant Tell that to us when a car alarm

01:39

goes off at four a m though it go skinny

01:41

for the early darn relevant no matter how long it's

01:43

going off anyway Useful Sure it's still not our answer

01:46

So say you finally convinced the kid to give you

01:49

some quiet time While you're basking in the peace and

01:52

quiet you begin to notice him sniffling every so often

01:55

snowed out related to that loopy from earlier Well at

01:59

first he tried to ignore it but for long all

02:01

you can focus on is that Yeah That's called sensitization

02:08

It's When you experience an increased response in this case

02:11

annoyance or anger or a burning desire to destroy things

02:15

to repeated stimulus in this case those terrible awful insufferable

02:18

sniffles terrible you know but also not our answer And

02:22

at least we know our four am car alarm Rage

02:24

is justified Well let's check our remaining option c and

02:27

eat We all know what electrocution is It's What happens

02:31

when you stick metal objects in an electrical socket It's

02:34

definitely not what our brains do on the daily So

02:36

cross out See that just leaves us with e trans

02:40

duck hsi in the process of converting outside stimuli and

02:42

converting or trans deuce ing it into electrical signals that

02:46

we can understand For instance your eyes gather a series

02:49

of light waves that the cells in your eyes then

02:52

convert into the perceived colors shapes and sizes that formed

02:56

the meal you just cooked as it flies directly from

02:59

the toddlers hands into your face Well hey better the

03:03

meal than the looky right So is the answer And

03:06

now if we could only find the right way to

03:08

deal with sensory stimuli overload caused by that car line

03:11

Well we're pretty sure it's not hitting the car with

03:13

a hammer But don't knock it till you try it
