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
Drugs can affect serotonin levels in the brain by either increasing or decreasing the amount of serotonin that is released or by changing how the brain processes serotonin. This can lead to changes in mood, behavior, and overall brain function.
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.
Cacao contains compounds that can increase serotonin levels in the brain. Serotonin is a neurotransmitter that plays a role in regulating mood and emotions. Consuming cacao may help boost serotonin levels, potentially improving mood and overall well-being.
Alcohol does not affect the cerebrum...rather it affects the cerebellum of the brain.
Yes
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...
Antihistamines work by blocking the action of histamine, a chemical involved in allergic reactions. Some antihistamines can also affect serotonin levels in the body by blocking the reuptake of serotonin in the brain, leading to increased levels of serotonin. This can result in side effects such as drowsiness and changes in mood.
Several chemicals affect emotions in the brain. The ones noted most in science are dopamine, nor-epinephrine, and serotonin.
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.
Oversleeping can disrupt the body's natural serotonin levels, which can lead to imbalances in the brain. This imbalance can trigger headaches as serotonin plays a role in regulating pain perception and mood.
Intoxication temporarily affects the operation of the brain.
No, but it will affect the decomposition of the human brain.
