Abstract

Intact mossy terminals observed in the granular layer of rat cerebella, two weeks after complete transection of all cerebellar peduncles, were identified as the endings of the intracerebellar nucleo-cortical afferents. A quantitative study of synaptic vesicle size spectra revealed clear differences between nucleo-cortical and true extracerebellar mossy afferents. These differences suggest that the nucleo-cortical afferents are recurrent collaterals of the projective nucleofugal fibers.
