Abstract

Single cell recordings were made from neurons in the lateral tegmental field of the medulla (LTFM) during electrical stimulation of the hypothalamic defense area (HDA) of the rabbit. Fifty-four cells were inhibited by HDA stimulation; 23 of these cells received barosensory input. Twenty-two LTFM cells showed an increase in firing rate during HDA stimulation; 10 of these cells received barosensory input. The results of this study provide evidence that the hypothalamic defense area makes functional connections with cardiovascular-influenced neurons in the LTFM.
