There are probably also costs & benefits involved in synthesizing, transporting and recycling various neurotranmitters in the differing chemical mileus of the brain.

Both glutamate and GABA are synthesized in the brain from the Krebs citricacid molecule alpha-keto glutarate — a reaction known as the

the rate-limiting enzyme in serotonin synthesis ..

The current state of knowledge about serotonin syndrome is mostly limited to case reports. Full understanding of its molecular biologic mechanisms is probably a number of years away. It is currently surmised that serotonin syndrome occurs when brain synapses are flooded by high levels of the endogenous neurotransmitter serotonin.[1] This only occurs through the action of serotonergic drugs.

High-estrogen contraceptives may have contributed to depression bylowering serotonin levels in the brain.

Serotonin concentration in the brain is far moresensitive to the effects of diet than any other monoamine neurotransmitter —and can be increased up to 10-fold by dietary supplementation in laboratoryanimals.

The site of greatest acetylcholine synthesis in the brain is the interpeduncular nucleus (located near the substantia nigra in the midbrain).

Melatonin is synthesized from serotonin in a 2-step process that takes an acetyl group from acetyl-CoA and a methyl group from by (S−Adenosyl Methionine).

The effectiveness of these neurotransmitters against depression seems to be due to both decreased functional activity of beta-postsynaptic norepinephrine receptors and increased activity of type−2 serotonin receptors in the limbic regions of the brain.
