There are two kinds of neurotransmitters - INHIBITORY and EXCITATORY. Excitatory neurotransmitters are not necessarily exciting - they are what stimulate the brain. Those that calm the brain and help create balance are called inhibitory. Inhibitory neurotransmitters balance mood and are easily depleted when the excitatory neurotransmitters are overactive.
Glutamic acid (glutamate) is probably the most abundant excitatory transmitter. Others can be excitatory, such as acetylcholine, and some peptides. Aspartate is also excitatory. Finally, serotonin is often found to be exctitatory.
Fatigue decreases the excitatory level of the spinal cord
Glutamate is the primary excitatory neurotransmitter in the central nervous system. It enhances the transmission of signals between neurons by promoting the depolarization of postsynaptic neurons.
