TLDR
P neurones constitute the direct T-C projection system mediating the superficial T- C response to the parietal cortex, and are concluded to constitute the basic type of the so-called recruiting response.Abstract:
1.
The cerebello-thalamo-cerebral projection system mediating the cerebellar-induced “superficial thalamo-cortical (T-C) response” (the basic type of the so-called recruiting response) to the anterior part of the middle suprasylvian gyrus was investigated electrophysiologically. Responses of thalamic neurones to stimulation of the cerebral cortex and the cerebellar nucleus (medial, interpositus and lateral) were recorded by microelectrodes.
2.
In the anterior portions of the ventral thalamic nuclear complex, presumably in and/or around the ventral anterior (VA) nucleus, there were found neurones responding antidromically to stimulation of the suprasylvian cortex and orthodromically to that of the interpositus and the lateral nucleus of the cerebellum. They were called P neurones. The neurones responding antidromically to stimulation of the anterior sigmoid cortex and orthodromically to that of the cerebellar nuclei located mostly caudo ventrolateral to the place of P neurones, presumably in and/or around the ventral lateral (VL) nucleus. These were called F neurones.
3.
The cerebellar excitation of P neurones was estimated on its latency to be monosynaptic and was usually followed by an inhibition lasting for more than 100 msec. Large unitary EPSPs were sometimes noted in P neurones on cerebellar stimulation as well as spontaneously. It was concluded that P neurones constitute the direct T-C projection system mediating the superficial T-C response (e. g., recruiting response) to the parietal cortex.read more

TL;DR: For example, this paper showed that autistic patients and patients with acquired cerebellar lesions were similarly impaired in a task requiring rapid and accurate shifts of attention between auditory and visual stimuli.

Thalamic relay nuclei for cerebellar and certain related fiber systems in the cat
TL;DR: Anterograde labeling techniques were used to define the terminal distributions in the thalamus of afferents arising in the deep cerebellar nuclei, entopeduncular nucleus and substantia nigra and none of the zones of termination of these fiber systems corresponds to commonly recognized cytoarchitectonic divisions.

Histochemical identification and afferent connections of subdivisions in the lateralis posterior-pulvinar complex and related thalamic nuclei in the cat
Ann M. Graybiel,David M. Berson +1 more
TL;DR: The finding of clear chemoarchitectural subdivisions in the lateralis posterior-pulvinar complex and adjoining regions has practical significance as a guide to thalamic organization and raises the possibility that some extrageniculate and related transthalamic pathways may be differentiated from one another by the neurotransmitters they employ in the thalamus.

A stereotaxic atlas of the cat brain
Ray S. Snider,William T. Niemer +1 more
TL;DR: There are excellent regional atlases for both the cat and the monkey, but these are the first to cover the brain stem and basal telenccphalon in such a complete fashion and should prove of particular value to people working in the caudal brain stem.

A study of thalamo-cortical relations

TL;DR: A topographical analysis of thalamo-cortical relations as revealed by alterations in the electrocorticogram induced by localized thalamic stimulation is presented, based upon the assumption that the complex spontaneous pattern of the cortex represents an aggregation of various sorts of activity.
