Abstract

Focal extracellular recording techniques were used to study nerve impulse propagation and the intermittent transmitter release mechanism in sympathetic nerve terminals of the guinea-pig vas deferens in vitro. In particular, the nature of impulse propagation in postganglionic nerve fibres was characterized following pre- or postganglionic stimulation. Conventional intracellular recording techniques were also used to study directly ganglionic transmission in cell bodies in the anterior pelvic ganglia. When brief electrical stimuli were applied to the hypogastric nerve trunk close to the prostatic end of the vas deferens, the nerve terminal impulses recorded extracellularly could be evoked eith..
