plz expound upon behavior traits of ppl lacking enough serotonin, dopomine, other neurotransmitters...?

Question:

i wish layman's terminology in explaining to me how neurotransmitters such as serotonin, etc. work in the brain and body, what behaviors are affected by too much or too little of them, how balances of all are achieved, and how to know if you have certain imbalances of any or a combination of same...?

Answers:
Well, bio-psychology is a soft science mostly.
Dopamine, serotonin, and norephinephrine are the three major neurotransmitters (also called monomines) believed to be responsible for many mental illness.

They are chemicals that are released from brain cells (neurons) and passed to another cell sort of like a message or code that tells the other cell what to do. When too much of this chemical is released, it excites the cell and sends it firing off electric signals everywhere. This might happen when we get excited or kiss our lover. They make you feel an abundance of joy. Yes, chemicals are responsible for our emotions, feelings, behaviors, and much more.

When there is too little of these chemicals released, the person feels depressed and unstimulated by most thing that normally would make them feel good.

There is physical evidence of the chemicals imbalances because they use F(MRI) Functional Magnetic Resolution Imaging machines to look inside of the human brain and see the electric reactions and where they take place in the brain. Usually there is a lack or abundance of activity in certain areas of the brain believed to be responsible for our emotions and moods in people with bipolar disorder. Also, they are able to measure the amount of the enzyme released from certain neurotransmitters by doing spinal taps and urine test.

Although most people can not afford these tests, most just are evaluated by a Psychiatrist and diagnosed.

Most common neurotransmitters that regulate emotions are Serotonin, Dopamine and Epinephrine (Adrenaline). In the absence of the above 3, Depression appears.
Epinephrine:
higher than normal: AD/HD
extremly high: Panic Dissorder
Dopamine:
higher than normal: Mania
extremly high: Schizophrenia

Serotonin: Serotonin syndrome may result when drugs that release
the neurotransmitter are mixed. For example Amphetamine
and MDMA (aka Ecstacy)
