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.
利用极微量注射L-谷氨酸（25 nl中含0.5 nmol或10 nl林格液中含0.1 nmol）的方法，已在兔中绘制出延髓尾端腹外侧部血管减压神经元的精确分布图。血管减压神经元离散地位于外侧网状结构的一个限定区域内，在疑核的腹侧和腹外侧，从闩尾端0.5毫米至2.5毫米处。结果表明，延髓尾端腹外侧部的血管减压神经元局限于一个相对有限的区域，与任何明确的核团均不对应。
