摘要
The precise distribution of vasodepressor neurons in the caudal ventrolateral medulla has been mapped in the rabbit using very small injections of l-glutamate (0.5 nmol in 25 nl or 0.1 nmol of 10 nl of Ringer solution). The vasodepressor neurons are discretely located in a circumscribed region of the lateral reticular formation, ventral and ventrolateral to the nucleus ambiguus, from 0.5 mm to 2.5 mm caudal to the obex. The results indicate that the vasodepressor neurons in the caudal ventrolateral medulla are confined to a relatively limited region, not corresponding to any defined nucleus. © 1990.
