Document Summary

Serotonin because when people are depressed, they have fewer serotonin receptors. Tend to see lower levels of serotonin in the brain and we believe that this is. Originates in (cid:498)older(cid:499) parts of the brain, evolutionary speaking. That"s why drugs keep serotonin in the same synapse longer so that the few receptors there are can pick up that serotonin, there"s more time to pick up the serotonin. This however is a hypothesis textbook will say it"s a fact. Researchers suspect that there are abnormal levels of serotonin in the brain hypothesis not fact. as if you are drunk). Think that there are low levels of norepinephrine in depression and abnormally high levels in mania. Depression has issues with reward processing, so possible relations of low dopamine in depressive people. *neuro transmitters hard to study in mood disorders. The claim that depression is a chemical imbalance in brain is bogus. May be true for some patients not others.
