ADD, Depression & Chronic Pain, Etc, Etc Pt6 2/3 User Manual 4 Humans

an output is to turn things off its inhibitory because otherwise the system

would just kind of run rampant and and get out of control because brain cells

are designed to fire so we need to kind of keep them in check and develop some

balance therefore most brain cells are inhibitory the vast majority so what is

it that the brain inhibits and when we talk about rain we're talking about the

cortex that's the outer portion the stuff that looks like a walnut so the

four things that inhibits and this sounds like mumbo jumbo and we'll just

run through it and we'll get back to it there's four forms of inhibition number

one is it inhibits anterior flexor muscles above t6 that's basically the

middle of the body and it turns off inhibits posterior flexors below t6

secondly it inhibits the inhibition and I'll explain that of anterior horn cells

three it inhibits your mi ml that is your stress response fourth it inhibits

secondary stimuli okay so that just kind of outlined so you can have them in one

place and will cover each of them and why this is some of the coolest stuff

that you have ever seen so the first one inhibition of anterior flexors and

posterior flexors this is what allows us to be upright to be biped rather than

quadruple and this is one of the most recent

developments in in evolution if you will that humans have a different brain than

four-legged animals and that brain the cortex is more developed and most of

that negativity of that cortex actually goes to regulate how we function as

two-legged creatures so here's how it works if you look at and then this is

one of my favorite records by the way this is super tramp and they have this

illustration that I borrowed so when when something is bent forward and the

arms are turned in and back that that's a flexible flexor posture if you think

about how babies are born they are if you put a baby down do they lie straight

and flat or do they kind of pull up like a rubber band their legs fall out and

they pull up are their arms really nice and straight or are their arms kind of

pulled in right because they haven't developed these reflexes to inhibit that

and what happens to older people as their brain activity decreases then they

start getting more crooked and going back into this posture again okay so

what is inhibition of anterior flexors it basically means that it's the muscles

of the shoulder and arm that in order for them to hang straight and for you to

be up right then those need to be turned off what happens in a stroke

when someone has a physical brain lesion that just kills off a whole bunch of

brain cells so they lose that inhibition then that shoulder will pull in the arm

will bend and the hand will flex this is called a decorticate means you could

disconnect in the cortex decorticate posture and you can look at any sort of

report on on brain trauma and you'll see things like that so we can look at

someone's posture and we can see which part of the brain is is weaker if

someone is standing like this and their hand left hand turns in like that we

know that's the weaker side of their cortex because it doesn't have the same

strength to inhibit those those movements all right if someone also has

has 2 stroke what you see on the on the posterior portion is we lose the

inhibition of posterior flexors so their foot is going to turn out and they're

going to come stand like this so those those are the most subtle

thanks to that you can look for but basically that inhibition is what

determines our ability to be upright and walk around and this is also why posture

is so important because when you have a stress response then you're

disconnecting the cortex and you're having less inhibition so what do

wrestlers and boxers look like you okay they're in a defense mode so they turn

they activate their their flexors by turning off that inhibition so anyone

who's threatened is going to look like this anyone who is at peace will look

like this so that means when people get really tense they do this so that means

when you try to relax when you try to make your brain work better you can help

out by finding a better posture it works both ways alright next in the abisha of

the IML that's a fancy word stands for intermedia lateral cell column and that

is basically where all of the cell bodies that give that live they give

rise to the sympathetic nervous system so those are the actual physical things

that give rise to a stress response and the brain inhibits those cells so what

does that mean it means that whenever you have a stress response that's going

to kick in automatically to save your life because you don't have time to

think about it whenever something surprises you you go on full alert

immediately but with a high functioning cortex that can quickly turn off that

stress response and balance your again the week of rain will not be able

to turn that off so quickly so that's why a lot of people stay in a stressed

state for a longer period of time that's when we run the math test in here the

people that have the best functioning brain you do the math and you have you

tell them to relax and they settle the right back down but the the better the

brain works the faster you'll turn back off and if it's not working so well then

that stress response just goes on and on and on okay so there's a reason that we

do that stuff so basically obviously this is hugely important the ability to

turn off the stress response because that everything we've talked about in

previous sessions all the diseases your healing response your digestion blood

pressure cortisol all those things the brain ultimately the cortex is what

turns off that stress response okay it's wired to turn it off but first the brain

has to be strong and function and this is huge the wording is funny

inhibition of inhibition of anterior horn cells so what is the anterior horn

cell do that's in your spinal cord there's a place called an anterior horn

and in the anterior horn that's the cells that send out signals to your

muscles that determine muscle tone and because you don't want your muscles to

be in a spasm because you want some regulation there's a default inhibition

there's a built-in turn off in the spinal cord of those of those cells so

when we want to turn on those muscles the basic muscle tone then the cortex

turns off those cell that turn off the motor response so a minus and a minus

becomes a plus essentially the brain determines the muscle tone in your body

the cortex is what senses and regulates that basic muscle tone so what does that

mean basically at the simplest level the muscle tone determines your reaction

time so if someone is walking and stumbles if you have a good high muscle

tone you will catch yourself very very quickly if you have a really slow really

low muscle tone and a really slow reaction time your face is going to hit

the floor before you know it and this is why elderly have so many Falls that's

why they're so unstable because their brain reacts so slowly

that they don't know that they're falling because before they're halfway

to the ground okay and I've looked up some statistics from the center of

Disease Control and falls are the number one cause of injury death in people over

65 there's over 18,000 that's a year there's 2.2 million Falls going to the

emergency room every year out of those five hundred eighty-one thousand are

hospitalized
