neu·ro·hu·mor·al trans·mis·sion

a process by which a presynaptic cell, on excitation, releases a specific chemical agent (a neurotransmitter) to cross a synapse to stimulate or inhibit the postsynaptic cell.
Synonym(s): neurotransmission


When a neurotransmitter, or chemical agent released by a particular brain cell, travels across the synapse to act on the target cell to either inhibit or excite it.


see nerve impulses.
