Modifies a noun

• synapse: Excitatory synapses have positive reversal potentials whilst inhibitory ones have negative reversal potential.

• neurotransmitter: Too many excitatory neurotransmitters released or too many of their receptors available can make this happen more easily.

• neuron: At least in theory, this will promote the chain reaction recruitment of excitatory, glutamatergic neurons outlined above.

• transmitter: Glutamate is present in abundance in brain tissue, and is the major excitatory transmitter in the central nervous system.

• acid: Glutamate One of the most important chemicals in the brain is the excitatory amino acid, glutamate.

• transmission: Since AMPA receptors mediate most excitatory transmission in the brain, then drugs acting at these receptors are likely to have physiological consequences.
