A classification of the parietal corticofugal neurons was performed in cats under Nembutal anesthesia. Eighty-eight neurons were identified with antidromic activation by the pontine stimulation. Thirteen neurons were furthermore identified with intracellular HRP staining. In these neurons, we found the close correlation between morphological features and conduction velocities. The faster conducting group of the neurons had relatively large somata, sparsely spinous apical dendrites, tap root basal dendrites and wide apical dendritic fields. The slower group had small somata and numerous dendritic spines.
在戊巴比妥麻醉下对猫的顶叶皮质传出神经元进行了分类。通过脑桥刺激以逆向激活的方式鉴定出88个神经元。另外通过细胞内辣根过氧化物酶染色鉴定出13个神经元。在这些神经元中，我们发现形态特征与传导速度之间存在密切关联。传导速度较快的神经元组具有相对较大的胞体、稀疏有棘的顶端树突、细根状的基底树突以及宽广的顶端树突野。传导速度较慢的神经元组具有较小的胞体和大量树突棘。
