it messes with the serotonin in your brain
Why do you experience pleasurable feeling when taking Ecstasy?
Because MDMA (Ecstasy) causes a flood of serotonin in your brain. Serotonin is the chemical that creates a sense of well-being and balances your mood. Ecstasy causes all the serotonin in your brain to be released at once. That is why people often feel depressed and unhappy for a day or so after taking Ecstasy. All of the serotonin in their brain has been depleted, and it takes awhile for your brain to replace it.
What is the precursor for serotonin and how does it impact the production of this neurotransmitter in the brain?
The precursor for serotonin is the amino acid tryptophan. Tryptophan is converted into serotonin in the brain through a series of chemical reactions involving enzymes. The availability of tryptophan in the body can impact the production of serotonin, as higher levels of tryptophan can lead to increased serotonin synthesis.
How do antidepressants work like Prozac?
If you are depressed, it makes you feel normal again, but it takes 3-5 weeks to kick in.
What does serotonin do for depression?
Serotonin is a brain chemical which we all have in our brains. It has 3 actions in the brain: 1. It gives us self-confidence, a feeling of safety and security. 2. It causes us to feel sleepy. 3. It increases our appetites. The part of the brain where it does each of these 3 things is a different part of the brain from the part where the other 2 things occur. Thus, for example, increasing serotonin in the part of the brain where self-confidence is will increase your self-confidence, but not your sleepiness. Unfortunately, we have no medications to increase only the serotonin in one part of the brain. This explains why medications to increase serotonin in the brain can also cause increased appetite and sleepiness. Medications which increase serotonin in the brain (SSRI's such as citalopram, escitalopram, fluoxetine, paroxetine, and sertraline and SNRI's such as venlafaxine and duloxetine) give us more self-confidence, and a feeling of safety and security. By the way, serotonin also exists in our gastrointestinal tracts. In this location, it stimulates digestion. This is why such medications can cause gastrointestinal upset. But they can also help constipation.
How do drugs affect the levels of serotonin in the brain?
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.
Why does Ecstasy have a hard crash?
Because MDMA (Ecstasy) causes a flood of serotonin in your brain. Serotonin is the chemical that creates a sense of well-being and balances your mood. Ecstasy causes all the serotonin in your brain to be released at once. That is why people often feel depressed and unhappy for a day or so after taking Ecstasy. All of the serotonin in their brain has been depleted, and it takes awhile for your brain to replace it. So, there is a comedown, or crash, after taking Ecstasy, but it is not nearly as bad as the comedown you get from other drugs, like speed and especially cocaine.
Do drugs increase serotonin levels in the brain?
Yes, drugs can increase serotonin levels in the brain by either blocking the reuptake of serotonin or by mimicking its effects.
What is the chemical in your brain that keeps you from killing people?
One of the primary chemicals responsible for regulating aggressive impulses is serotonin. Low levels of serotonin have been associated with increased aggression and impulsivity. serotonin is involved in regulating mood, emotions, and behavior.
How do antihistamines affect serotonin levels in the body?
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.
What is function of serotin?
Im assuming you're meaning serotonin, which you most likely are. Here are some compiled facts about what serotonin is ,works ,functions and functioning.Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter in the brain that has an enormous influence over many brain functions. It is synthesized, from the amino acid L-tryptophan, in brain neurons and stored in vesicles. Serotonin is found in three main areas of the body: the intestinal wall; large constricted blood vessels; and the central nervous system. The most widely studied effects have been those on the central nervous system. The functions of serotonin are numerous and appear to involve control of appetite, sleep, memory and learning, temperature regulation, mood, behavior (including sexual and hallucinogenic behavior), cardiovascular function, muscle contraction, endocrine regulation, and depression.Of the chemical neurotransmitter substances, serotonin is perhaps the most implicated in the treatment of various disorders, including anxiety, depression, obsessive-compulsive disorder, schizophrenia, stroke, obesity, pain, hypertension, vascular disorders, migraine, and nausea.The linkage of serotonin to depression has been known for the past five years. From numerous studies, the most concrete evidence of this connection is the decreased concentration of serotonin metabolites like 5-HIAA (5-hydroxyindole acetic acid) in the cerebrospinal fluid and brain tissues of depressed people. If depression, as suggested, is a result of decreased levels of serotonin in the brain, pharmaceutical agents that can reverse this effect should be helpful in treating depressed patients. Therefore, the primary targets of various antidepressant medications are serotonin transports of the brain. Since serotonin is activated when released by neurons into the synapse, antidepressants function at the synapse to enhance serotonin activity. Normally, serotonin's actions in the synapse are terminated by its being taken back into the neuron then releases it at which point "it is either recycled for reuse as a transmitter or broken down into its metabolic by products and transported out of the brain." As a result, antidepressants work to increase serotonin levels at the synapse by blocking serotonin reuptake.According to other researchers, an even better way to raise serotonin levels would be to get daily exercise. The most effective way of raising the serotonin level is with vigorous exercise. Studies have shown that serotonin levels are raised with increased activity and the production of serotonin is increased for some days after the activity. This is the safest way of increasing the serotonin level and there are numerous benefits to be gained by regular exercise. In observing these findings, there is a basic understanding of serotonin and its functions. Serotonin is recognized as a very important neurotransmitter that has a profound effect on many aspects of behavior. Extensive research has been done, and is being continued, on the complex mechanisms by which serotonin operates. The most useful outcome of such studies is the introduction of pharmaceutical agents into the medical community. New studies are conducted everyday to learn more about the exact nature of serotonin and its widespread use throughout the human body.Sorry if this is too much information for the question, but the question is very complex.
What is the opposite of dopamine and how does it affect our brain's reward system?
The opposite of dopamine is serotonin. Serotonin plays a role in regulating mood and emotions, and when its levels are low, it can affect the brain's reward system by causing feelings of depression and decreased motivation. This can lead to a reduced ability to experience pleasure and satisfaction from activities that would normally be rewarding.
