Answer 2

From what I've been reading doing a project about neurons and their ability of transporting information, there should be 4 major systems of neurotransmitters, they are:
* The dopamine system.
* The norepinephrine system.
* The cholinergic system.
and
* The serotonin system.
Each system have different targets and thereby different effects, it might be worth to look at the generally tendency of the systems.

Answer 3

I believe it's a mix. Each neuron has the capability to many different things, usually, so based on which neurotransmitter in which concentration, it'd probably be different. I think some may be specialized to a single neurotransmitter, and some may have several, a mix of every possible combination, if you know what I mean.
