Abstract

Alligator Purkinje cells generate action potentials in the peripheral dendritic tree, after synaptic depolarization via superficial parallel fibers. These action potentials are inhibited at the dendrite level by preceding parallel-fiber volleys at close intervals. We conclude that this inhibition is produced by the activation of the inhibitory interneurons of the molecular layer, the stellate cells, which establish synaptic contacts with the dendrites of the Purkinje cells.

摘要

短吻鳄浦肯野细胞在通过浅表平行纤维进行突触去极化后,在外周树突中产生动作电位。这些动作电位在树突水平受到紧密间隔的先前平行纤维群峰的抑制。我们得出结论,这种抑制是由分子层抑制性中间神经元(即星状细胞)的激活所产生的,这些星状细胞与浦肯野细胞的树突建立突触联系。
