摘要
Actions of thyrotropin-releasing hormone (TRH) on submucous neurons of the guinea-pig ileum were examined with intracellular electrophysiological methods. TRH evoked excitatory responses in S/type 1 and AH/type 2 neurons. The responses consisted of slowly activating membrane depolarization, augmented excitability and an increase in input resistance that resulted from a decrease in potassium conductance. The results suggest a neuromodulatory/neurotransmitter function for TRH.
