THE INHIBITORY AND ACCELERATORY SYNAPSES IN A CRUSTACEAN HEART GANGLION.

Abstract

The purpose of the research is to elucidate the mechanism of inhibition and acceleration at the synapse in the nervous system. The heart ganglion of a stomatopod Crustacea supplies an excellent material for the study. The inhibitory and acceleratory axons are stimulated, and the potential changes are recorded from the postsynaptic cells with intracellular microelectrodes. It is concluded that the acceleratory effect is not mediated by the excitatory postsynaptic potential (EPSP) but is due to a direct action of the transmitter in the pacemaker membrance. (Author)
