> motivation=NEI don't think motivation is linked to anyone one brain chemical as it is a general term
for example, i believe i read once that "dopamine is responsible for the initiation of behaviours, norepenephrine is responsible for the continuation of behaviours, and serotonin is responsible for mood" ....
i know the nucleus accumbens is supposed to be responsible for reward, and it is effected by dopamine, serotonin, and norepenephrine ... though mostly dopamine, it would seem ... i mean we all know that different serotonin receptors have different effects on dopamine neurons (inhibitory or excitory) for example, 5HT2A receptors have an inhibitory effect on dopamine neurons in the nucleus accumbens
i also believe the emotion of "joy" is related to the globus pallidus, which is believed to be a dopamine-rich area...
