neurotransmission


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

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

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.

These reductions correlate with behaviors related to depression, which could indicate a decrease in GABAergic neurotransmission because parvalbumin is one of the proteins present in GABAergic interneurons (Leussis, Freund, Brenhouse, Thompson, & Andersen, 2012).
As the above results suggest, propofol medicates GABAergic neurotransmission through pre- and post-synaptic pathways and etomidate regulates GABAergic neurotransmission through a postsynaptic mechanism.
Of particular importance is the high prevalence of drug abuse of combined MA and morphine among polydrug addicts; whether DAergic and 5-HTergic neurotransmission in the NAc play critical roles in addiction to co-administered MA with morphine still awaits elucidation.
