The biochemistry and electrochemistry of the neuron (starting with a drawing of the neuron). Draw a star-like structure and put a circle in it. The star-space is the <b>soma</b> ("body"). The nucleus is the brain of the neuron. Of of each of the points, draw a squigly line. These are the dendrites (branches). Put a bunch of dots on them. Those are the <b>receptor sites</b>. Then draw the axon. And then draw three mushroom-like structures. That's the axon terminal. So you have the soma, axon, and axon terminal. One of the little buds is known as either the "axon bud" or "button." There are vesicles in the axon terminal buds, and there are dots in the vesicles, they are neurotransmitters. The Myelin sheath is known as white matter, it's fatty and white, really soft and jell-oey, and it prevents two axons of nerves from crossing transmissions, kind of like touching two live copper wires and electricity jumping between them. It's an insulator. It's white. That means the nerves in the body are white. <b>Brain matter has no Myelin sheath.</b> Grey matter is for brains.

<br /><br />

Why do you not need the Myelin sheath in the brain?
<br /><br />

There are seven neurotransmitters that we will study: serotonin, dopamine, etc. You can "blend" neurotransmitters together, so there are several different ones. You can releave nerve impengement. There's the <b>"All or none law."</b> The nerve can only fire all the way or not at all. It cannot fire partially, it can't fire a quarter of the way, it fires all the way when it is going to fire, it's like pulling a trigger on a gun.

<br /><br />
The neuron has a <b>refractory period</b>- 15 ms. Every nerve has the "all or none law" and a refractory period. The refractory period can be changed, so it can fire faster in certain situations. The axon terminal can occassionally gain new buds with new vesicles.

Insert some information here about synesthesia, hallucinogens, tripping, LSD/acid, etc.<br /><br />

- tryptophan<br />
- cocaine blocks dopamine receptors<br />
- so there's this rise in dopamine in metabolism and brain functions, flood of dopamine<br />
- serotonin is responsible for moods, if you don't have enough you're depressed<br />
- <u>we can't yet manufacture neurotransmitters</u><br />
- We give you Prozac if you don't have enough serotonin, which means that the gap floods with serotonin

Chemical composition of your neuron<br />
- Potassium deficiencies means that your neurons tell your muscles to contract. So the muscles contract. The way to fix this is to get more potassium. Bioavailable potassium. Bannanas do not have potassium that is immediately usable. See the old Buckley notes on myocytes and potassium.<br />
- Saline<br />
- 

<br /><br />
<h2>Nerve impulse</h2>
Potassium, calcium, saline, and then there are some deficiencies that lead to nerve disorders if you don't have a healthy diet. Your mycoytes do not function well when neurons aren't functioning well.
