ADD, Depression & Chronic Pain, Etc, Etc Pt6 1/3 User Manual 4 Humans

excited to launch the sixth part 6 piece of user manual for humans and I'm always

amused when people what's the topic because then in their mind are going

over and saying well if it's such a topic that I'm interested but if it's

such a topic I'm not and then they really miss the point of holism because

everything that we talked about really is the same thing but we just use

different words and we're approaching it from different directions but there

really is just one topic in holism is how does the stuff work and how do we

make it work better and today we'll talk about AD depression and chronic pain etc

etc because that's that's just the tip of the iceberg there's so much more that

that is part of the same mechanism and what is the common denominator we'll get

to that in a few slides but just some brain basics we're going to talk about

brain cells and we'll go into a little bit more detail than we have before and

bear with me because that lays the foundation so that you understand the

bigger picture as we finish up brain cells were called neurons they make up

two percent of your body mass but they use twenty percent of your

energy twenty percent of the blood in the body is sent to the brain so that

means that the brain cells are doing a whole lot of work because that's the

purpose of blood is to provide energy for work so that means that the brain is

actually a very very busy bee that the brain cells are doing a whole lot more

work than the average cell and what is the work that they do they process

electrical signals that's what they do and we're going to call that we're going

to put a unit on it millivolts it's a current of electricity and we'll talk

about that in a bit so there's a few concept will cover their resting

membrane potential summation and inhibition and facilitation we'll get to

that so don't get scared by the fancy words some more brain basics at birth

the brain weighs about 340 grams that's 12 ounces and the adult brain weighs

about 1,450 grams or three pounds so from birth to adulthood the brain

increases in weight four times yet both have about a hundred billion

neurons they have the same number of brain cells at birth as we do as adults

so what's the difference well the you're born with all the neurons but then as

you start learning as you start behaving as you start interacting with your

environment those neurons are trying out your environment by trial and error

making synapses they're sending out little connections and as they make more

and more connections you start making neural networks and the difference in

weight is the synapses okay each brain cell makes bets on the next slide each

neuron makes about 4,000 to 10,000 connections and all of those connections

all those wires is what makes the difference in the weight so when people

talk about grey matter they're talking about the brain cell itself and when

they're talking about white matter they're talking about a white insulation

that covers those threads those wires because we're dealing with electrical

circuitry so we want to make sure that we have good insulation and that's what

the white matter is so if you think about this now every skill

that you have every habit that you have and everything that you will ever learn

or forget is a network of synapses so as you learn you make new synapses as you

as a skill falls out of favor as you stop doing something you just simply

stop reinforcing those synapses and if you don't use them you lose them but as

you acquire new skills it's through making new synapses and these

connections are ever changing throughout your life they're always changing you

can be 90 years old and you can still learn new things that's because you can

still make new synapses your brain can change regardless of your age and it

does this at any age next resting membrane potential so here we have to

understand something about brain cells this is an inherent property in brain

cells that over on the left side of the scale it says 50 and 60 those are

millivolts so let's say that the membrane potential the difference in

charge between inside and outside of the cell is 50 millivolts just like a

battery and if you get to 55 nothing will have

but once you get to 60 hypothetically speaking I just take that number then

everything breaks loose all at once it's an all-or-nothing response so that cell

has an action potential all the gates flood open and everything happens all at

once that's the only way you can get a brain cell to react before you reach

that level of action potential nothing happens so this is really really

important to understand and when you look at the next diagram number 5 so

this looks a bit complicated but I'll explain it to you so these are five

different cells five different brain cells ABCD and E in the middle and they

all have different synapses the little strand that looks like a why there

that's a synapse and a synapse can be inhibit inhibitive or facilitative it

means it can turn something on which means it contributes a plus or it can

inhibit something which means it's subtract and what is it subtract and add

to that resting membrane potential ok so the activity of a brain cell the

perception of a brain cell is determined by other brain cells and remember we

have a hundred billion of these and they each make about four to ten

thousand synapses so can you see that that can get pretty complex by the time

you add a few thousand connections so let's look at this we have cell number E

its resting membrane potential is 50 millivolts and we know that if something

makes it reach 60 then it's going to fire off an action potential before it

gets to see ste nothing happens so we have cell a cell a is an inhibitory sell

its NT minus 6 charge to that cell so now that cell is that is at 44 so it's

further away from firing so the responsiveness of cell II has been

dampened we look at selby it adds five so now we're on a net minus one and

we're at 49 so we're still a little bit further away and then we have cell C

which adds and we have Selvi which subtracts and then we have on the left

side we have an incoming signal and that represents an incoming signals from the

body so let's say that you stub your toe and

that represents a signal plus 10 now whether this brain cell receives the

message determine is determined by the other brain cells if the sum total adds

up to 60 or not makes sense so this is how the brain creates stability because

if a brain cell is really really close to firing then just about anything is

going to send it off and those are people who are hypersensitive to things

okay if the resting membrane potential is too low then that brain cell is very

unresponsive so that would be a person who is less responsive than they then

they need to be in many regards so the functioning nervous system font works to

automatically find the ideal level but in order for this to happen we need to

use the brain cells and we need to keep these networks active so that's where

chiropractic and exercise and activation of the system comes in

that's why I keep nagging about exercise and about doing things alright any

questions so far okay everything's making sense very good now we get to the

really cool stuff as it turns out in order to provide stability in the body

most of the
