47 reticulospinal neurons of the lamprey brain-stem were stained by intracellular injection of Procion yellow, so that their morphology and dendro-architecture could be determined. The vagal, bulbar, Mauthner, isthmic and mesencephalic groups could be distinguished by the shape and size of their somata and the distribution of their dendrites. However, they shared the following features: the somata of all these cells were relatively large (up to 80 micrometer largest diameter); the dendrites were extensively distributed in the brain-stem in an open-field arrangement; the initial segment expanded abruptly at the soma junction but tapered gradually to form a narrow axon, which joined the medial longitudinal fasciculus in the brain-stem.
通过向七鳃鳗脑干的47个网状脊髓神经元内注射普罗黄进行染色，从而确定它们的形态和树突结构。迷走神经、延髓、莫纳氏细胞、峡部和中脑组可根据其胞体的形状和大小以及树突的分布加以区分。然而，它们具有以下共同特征：所有这些细胞的胞体相对较大（最大直径可达80微米）；树突在脑干中呈开放场排列广泛分布；起始段在胞体连接处突然变宽，但逐渐变细形成一条细轴突，该轴突在脑干中与内侧纵束相连。
