    There are many different ways to classify neurotransmitters. Dividing them into amino acids, peptides, and monoamines is sufficient for some classification purposes.

    Major neurotransmitters:

    Amino acids: glutamate, aspartate, serine, γ-aminobutyric acid (GABA), glycine

    Monoamines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, serotonin (SE, 5-HT), melatonin

    Others: acetylcholine (ACh), adenosine, anandamide, nitric oxide, etc.

    In addition, over 50 neuroactive peptides have been found, and new ones are discovered regularly. Many of these are "co-released" along with a small-molecule transmitter, but in some cases a peptide is the primary transmitter at a synapse.

    Single ions, such as synaptically released zinc, are also considered neurotransmitters by some, as are some gaseous molecules such as nitric oxide (NO) and carbon monoxide (CO). These are not classical neurotransmitters by the strictest definition, however, because although they have all been shown experimentally to be released by presynaptic terminals in an activity-dependent way, they are not packaged into vesicles.

    By far the most prevalent transmitter is glutamate, which is excitatory at well over 90% of the synapses in the human brain. The next most prevalent is GABA, which is inhibitory at more than 90% of the synapses that do not use glutamate. Even though other transmitters are used in far fewer synapses, they may be very important functionally—the great majority of psychoactive drugs exert their effects by altering the actions of some neurotransmitter systems, often acting through transmitters other than glutamate or GABA. Addictive drugs such as cocaine and amphetamine exert their effects primarily on the dopamine system. The addictive opiate drugs exert their effects primarily as functional analogs of opioid peptides, which, in turn, regulate dopamine levels.

    Milly is happy and dopey all rolled into one, she's always happy, yet she's a little dopey, but she is chocolate after all...LOL Amy is grumpy, l'm sure the older she gets the grumpier she gets, although it might just be Alfie that's making her grumpy!!! Alfie is sleepy, he runs around like a lunatic then falls asleep, normally on me! Best thing about having a dog in my life....there's not just one thing, it's everything about them.
