What does the substantia nigra do?

What does the substantia nigra do?

A lot!: Whole chapters in neuroanatomy are dedicated to the substantia nigra, but a short answer would be: it is indirectly involved with our muscle control including eye movement, and also the reward seeking/addictive, and learning aspects to our brain. When this part of the brain is damaged it causes parkinson's disease.

What makes stimulating the substantia nigra cause depression?

What makes stimulating the substantia nigra cause depression?

Dopamine: Stimulation (presumptively by amphetamines) causes a release of dopamine. If this is "supraphysiological" - i.e., more than the body would normally account for - you can end up with a Dopamine deficit. This is the same think as Cocaine addicts have after a run on cocaine, or crank or meth addicts have after a run. The good news is that the body can and will build it back up if allowed to.

Can I smoke??

Can I smoke??

No. Of course not.: Not a good thing to do. The intentional habit of inhaling burning organic material, combined with various chemicals used in the growing and manufacturing of that material (regardless of whether it is tobacco, marijuana, or any other plant) is bad for the body. Just think about it. Who would intentionally start something burning and inhale the stuff over and over and over?

Is lead safe?

Is lead safe?

Not if inside us...: Lead is naturally occurring on earth. Outside of our bodies, lead is not a problem. If we eat or drink too much of it, it becomes a toxic contaminant inside our bodies. Lead is everywhere in our industrialized world, which means one shouldn't worry too much about it, but be sure our families are not eating or drinking things containing lead, nor using lead-contaminated containers or toys.

How to get fat?

How to get fat?

See below: First of all, I don't suggest getting "fat" as it brings about many hazards. But if you are underweight and want to gain weight, do so by increasing your calorie intake. You need to consume more calories than you burn. Don't do this by eating a lot of junk food. Make sure you're getting all your essential nutrients. Also, you can gain muscle mass by weight lifting or other activities like that.
