The mode of cerebellar activation of neurons in the cat motor cortex: an intracellular HRP study.
Intracellular recordings and morphological identification of neurons by using intracellular HRP staining were performed in the cat motor cortex. By cerebellar stimulation, stellate cells in layers II-III, pyramidal cells in layer III and fast pyramidal tract neurons (PTNs) were activated with short latency and fast rising EPSPs, while pyramidal cells in layer II and slow PTNs showed a wide range of latency and slow rising EPSPs. This difference may be related to activation through the deep and superficial thalamocortical projections.
