Effects of diazepam were examined on the whine reaction elicited by LH stimulation and on unit activities in the LH and Abm in cats. The spontaneous firing frequency of Abm neurons was 5 to 30 spikes/sec and in all 6 neurons isolated the firing frequency increased by non-nociceptive and/or clap-stimulation. Diazepam decreased the spontaneous firing frequency of all Abm neurons isolated and the increased firing frequency elicited by non-nociceptive and/or clap-stimulation was also depressed by diazepam. The spontaneous firing frequency of neurons in the LH was 4 to 5 spikes/sec and all 6 neurons isolated firing frequency increased by non-nociceptive stimulation. Only one of 6 neurons, however, was activated by clap-stimulation. Diazepam decreased the spontaneous firing frequency of all LH neurons. Out of 6 neurons responsive to non-nociceptive stimulation, 3 were also depressed by diazepam. The other neurons were not affected by diazepam. These results suggest that depressed action of diazepam on the whine reaction elicited by the LH stimulation may be related to the decrease of firing in the Abm and/or the LH by diazepam.
