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
