Abstract：
:Using the in vitro hamster hypothalamic slice preparation, the effects of GABA and 80% chloride (Cl-) reduced medium on the single unit activity of SCN neurons was investigated. GABA 10(-4) M produced inhibitory responses in 55% of the 69 SCN neurons examined. No statistically significant day-night difference was observed in either the percentage of SCN units responding to GABA, or in their threshold response. During the day 80% Cl- reduced medium had an excitatory effect on SCN neurons; however, following the return to normal Cl- concentrations a transient, but significant inhibition was observed. During the night, 80% Cl- reduced medium produced an excitatory response similar to that observed during the day, but no inhibition following return to the medium containing normal Cl- concentrations. Only during the night was Cl- reduced medium found to initiate activity in a dose-dependent manner in some silent cells. No significant day-night difference in response to 80% Cl- reduced medium occurred in neurons of the paraventricular nucleus of the hypothalamus. These results indicate that SCN neurons whose activity is mediated by Cl- may be involved in the control of circadian rhythms.
