Post-tetanic depolarization in sympathetic neurones of the guinea-pig

AUTOR(ES)
RESUMO

1. Repetitive intracellular stimulation at a frequency of 5-30 Hz for 1-10 s evoked in neurones of the isolated inferior mesenteric and superior cervical ganglia of the guinea-pig three types of post-spike membrane potential changes: (i) hyperpolarization, (ii) hyperpolarization followed by a slow depolarization, and (iii) a second hyperpolarization following the initial two responses.
