Detailed explanation-1: -Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine. Inhibitory. Inhibitory neurotransmitters block or prevent the chemical message from being passed along any farther. Gamma-aminobutyric acid (GABA), glycine and serotonin are examples of inhibitory neurotransmitters.

Detailed explanation-2: -Glutamate is the major excitatory neurotransmitter in the mammalian brain. Fast transmission mediated by this neurotransmitter accounts for synaptic excitation of most, if not all, brain neurons (Kandel et al. 2000), and thus glutamate is found throughout the brain.

Detailed explanation-3: -Four neurotransmitters come under the chemical classification of biogenic amines. These are epinephrine, norepinephrine, dopamine, and serotonin.
