This is an incredibly broad question. The basic theory is that many drugs force there to be an excess of serotonin in the synapse of a neuron, by either stopping the re-uptake of it (antidepressants) or by other complex actions (amphetamines). The addicts nervous system begins to take note of this and not produce/release as much serotonin, this leads to a state of low level endogenous serotonin production, thus leading to withdrawal and craving. By taking said drug again, the patient is able to feel normal again. It should be noted that this is an extremely simple explanation of this, and that addiction is a VERY complex topic.. Dr. Dan
I'm not a doctor but from what I understand they have a kind of "tug of war" relationship (dopamine and serotonin , Adderall works primarily on dopamine). One (dopamine) stimulates, the other (serotonin) inhibits or"calms". I believe adderall may initially boost serotonin a bit along with dopamine and norepinephrine but eventially depletes it.(Hence the real irritability on the comedown)SSRI's can reduce this effect a bit.Anyway I'm researching the same thing so that's the best I could come up with so far. Good luck on your recovery.
Alcohol raises serotonin levels in the short term, but repeated usage lowers serotonin levels, because alcohol causes the brain to eventually run out of serotonin.
They affect GABA, NMDA, opiod, adrenergic, histamine and acetylcholine receptors in your brain. Depressants can effect other parts of your brain aswell, these are just the parts of it that actually cause the depressant effects of the drugs. Alcohol for example effects the GABA, NMDA, acetylcholine and serotonin receptors but it's effect on the serotonin receptor doesn't cause any depressant effect but rather adds to the euphoric effects of alcohol.
Some animal studies have shown that MDMA can negatively affect the serotonin system in the brain and damage neurons
Alcohol does not affect the cerebrum...rather it affects the cerebellum of the brain.
Yes
Several chemicals affect emotions in the brain. The ones noted most in science are dopamine, nor-epinephrine, and serotonin.
Most drugs are similar in structure to neurotransmitters, and mimic their effect in the brain. Others will inhibit neuro transmitters as well. Alcohol -> GABA LSD -> Serotonin Cocain -> adrenalin morphine - endorphine etc...
Zoloft is an SSRI (selective serotonin reuptake inhibitor). Tramadol is a painkiller with SNRI (serotonin and noadrenalin reuptake inhibitor) properties. This means that both Zoloft and tramadol have an effect on the neurotransmitter serotonin in the brain. This can result in too much serotonin in the brain. This is called Serotonin Syndrom, a very dangerous condition. Never mix multiple drugs that affect serotonin.
Intoxication temporarily affects the operation of the brain.
No, but it will affect the decomposition of the human brain.
Alcohol is an anesthetic so it numbs your brain, and it is also toxic, so it destroys your brain cells. Whatever you were, after alcohol you're less.
It temporarily slows the operation of the brain.
