用尼氏染色和Bodian染色的连续横切切片研究了美西蝾螈（Ambystoma mexicanum）脑干的室沟型和细胞结构。纵沟、下正中沟、腹中间沟、界沟、背中间沟、上级正中沟和中脑外侧沟共6条。第七个沟，沟峡，明显偏离其他沟的整体纵向模式。虽然大多数神经元胞体包含在弥漫性室周灰质，19个细胞团可以划定：其中7个是初级传出或运动核，4个是初级传入或感觉中心，4个核被认为是网状结构的组成部分，其余4个细胞团可以解释为“中继”核。
The ventricular sulcal pattern and the cellular structure of the brain stem of the axolotl Ambystoma mexicanum have been studied in transversely cut Nissl and Bodian stained serial sections. Six longitudinal sulci, the sulcus medianus inferior, the sulcus intermedius ventralis, the sulcus limitans, the sulcus intermedius dorsalis, the sulcus medianus superior and the sulcus lateralis mesencephali could be distinguished. A seventh groove, the sulcus isthmi, clearly deviates from the overall longitudinal pattern of the other sulci. Although most neuronal perikarya are contained within a diffuse periventricular gray, 19 cell masses could be delineated: seven of these are primary efferent or motor nuclei, four are primary afferent or sensory centers, four nuclei are considered as components of the reticular formation, and the remaining four cell masses can be interpreted as “relay” nuclei.
