Pre- and postsynaptic effects of taurine and GABA in the cockroach central nervous system.

Taurine resembles GABA in its synaptic effects in the cockroach cercal nerve giant fiber synapse where it exerts a depressant action upon synaptic transmission. Both taurine and GABA produce an increased conductance of pre- and postsynaptic membranes through changes in the permeability of chloride ions.
