title: Electrophysiological properties of cortical synaptic inputs of rubro-spinal neurons.
abstract: Excitatory postsynaptic potentials (EPSPs) of the red nucleus neurons evoked by stimulation of the cerebellar nucleus interpositus as well as the sensorimotor and association parietal regions of the cerebral cortex were studies in acute cats. As for the first two structures, a monosynaptic connection of the association cortex with rubro-spinal neurons was shown to exist. The analyses of the time characteristics of the unitary EPSPs suggested a localization of synapses of fibers from the association cortex closer to the soma when compared with those which originated from axons of the sensorimotor cortical cells.
