Does recurrent inhibition exist in the paraventricular magnocellular neurosecretory cells in the male rat?
Extracellular recordings were performed from the paraventricular (PVN) neurosecretory cells in the anesthetized male rats. After sub- and suprathreshold stimulations to the neural stalk, two of 38 neurons showed inhibitory phases and eleven of the remaining 36 neurons showed inhibitory responses after suprathreshold stimulations. These results indicate that the recurrent inhibitory system exists in the PVN.
