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… WebWhen activated by slow synaptic inputs, behavior of AH-type neurons is much like that of S-type neurons and may be confused as such, if the AH-type neurons happen to be in an activated state due to ongoing release of the transmitter. Postspike hyperpolarization in AH-type neurons is suppressed during slow excitatory neurotransmission.
