Excitatory Neurotransmitters Amino Acid Therapy

An excitatory synapse is a synapse in which an action potential in a presynaptic neuron increases the probability of an action potential occurring in a postsynaptic cell. Neurons form networks through which nerve impulses travel, each neuron often making numerous connections with other cells. These electrical signals may be excitatory or inhibitory, and, if the total of excitatory influences exceed… WebHistorically, the most compelling evidence that glutamate and aspartate function as neurotransmitters came from the observation that at low concentrations they excite virtually every neuron in the CNS.
