Abstract

Features of action potentials and synaptic potentials as obtained by intracellular recordings from the sympathetic ganglion cells in the superior cervical ganglion of both the rat and the guinea-pig are described. Time-constant, imput resistance and capacitance of the ganglion cell membrane were also measured. Rheobasic currents and chronaxies are evaluated from strength-latency recordings. Single stimulating shocks applied to pre-ganglionic fibres produce repeated activation in the sympathetic ganglion cells and neuron response appear to be dispersed over a considerable length of time. Simultaneous recordings of extracellular post-ganglionic discharge and intracellular response from single ganglion units showed that pre-ganglionic fibres with different conduction velocities converge on the neurons. This convergence can fully justify the temporal dispersion of the ganglion cell responses. © 1970 Springer-Verlag.
