What Does Serotonin Do? Te following figure shows the serotonin pathways through brain. Te primary function of serotonin is to transmit nerve impulses across nerve cells and neurons. I should be noted that neurons is responsible for raw data from different parts of body organs to the brain. Aain, ater processing the information brain gives instructions to body organs through the same neuron. I short, nuron activity is important in keeping all bodily activities intact. Wen variations occur in serotonin content in our body, cmmunication between brain and may not work properly.

Dpression is mainly seen among females even though it is common among males also. Mdical science was confused about this discrepancy in the occurrence of depression among males and females. Hwever, rcent studies have shown the reasons. “cientists from the Karolinska Institutet, Seden, sowed that the brain's serotonin systems in males and females are different. Tey think they might have found one of the reasons why more women are affected with depression and chronic anxiety than me” Do? Aart from Serotonin, dpamine, nrepinephrine, mlatonin, isulin are some other chemicals which affect mood and emotions.

Dpamine is also an aromatic compound in organic chemistry. I is a kind of neurotransmitter which controls the movement of emotional responses. Dpamine deficiency can cause not only depression, bt also other disorders such as schizophrenia, Prkinson’s disease etc. “harmacological treatments support the idea that an overactive dopamine system may result in schizophrenia: Mdications that block dopamine receptors, secifically D2 receptors, rduce schizophrenia symptoms. Te brain regions known as the thalamus and the striatum are affected by dopaminergic activity” Te dopamine (DA) and the dopaminergic neurones play an important role in schizophrenia and Parkinson's disease (PD).

Adecrease in DA in the substantia nigra of the brain has been implicated as the cause of PD. B contrast, i is argued that a functional excess of DA or oversensitivity of certain DA receptors is one of the causal factors in schizophrenia. Tese factors are reflected in the treatment of both conditions; dugs aimed at increasing DA. ..
