TLDR
The rostral dorsal accessory olive contains a detailed somatosensory map of the entire contralateral body surface and it is demonstrated that the sensory somatotopy of rDAO aligns with the motor somatOTopy of NIA.Abstract:
The rostral dorsal accessory olive (rDAO) contains a detailed somatosensory map of the entire contralateral body surface. The rDAO projects to the anterior interpositus nucleus (NIA) directly as well as indirectly by way of Purkinje cells in cerebellar cortex. NIA maintains a topographic relation to different levels of the spinal cord through a relay in the magnocellular red nucleus (RNm) and, thus, contains a motor somatotopy. By using bidirectional transport of WGA-HRP, we demonstrate that the sensory somatotopy of rDAO aligns with the motor somatotopy of NIA. It is likely that rDAO information supplied to the cerebellum from a specific part of the body is used to influence movements restricted to that same body part.read more

Feature Article: Distributed Modular Architectures Linking Basal Ganglia, Cerebellum, and Cerebral Cortex: Their Role in Planning and Controlling Action
James C. Houk,Steven P. Wise +1 more
TL;DR: The motor system includes structures distributed widely through the CNS, and a scheme for how they might cooperate in the control of action is presented, including interconnections among the basal ganglia, cerebellum, and cerebral cortex.

Does the nervous system use equilibrium-point control to guide single and multiple joint movements?
TL;DR: The hypothesis that the central nervous system generates movement as a shift of the limb's equilibrium posture has been corroborated experimentally in studies involving single- and multijoint motions and can now be investigated in the neurophysiological machinery of the spinal cord.

Does the nervous system depend on kinesthetic information to control natural limb movements
Simon C. Gandevia,David Burke +1 more
TL;DR: In this paper, the authors draw together two groups of experimental studies on the control of human movement through peripheral feedback and centrally generated signals of motor commands, concluding that subjects can perceive their motor commands under various conditions, but that this is inadequate for normal movement.

The representation of egocentric space in the posterior parietal cortex.
TL;DR: The posterior parietal cortex is the most likely site where egocentric spatial relationships are represented in the brain and does not seem to contain a "map" of the location of objects in space but a distributed neural network for transforming one set of sensory vectors into other sensory reference frames or into various motor coordinate systems.

On the specific role of the cerebellum in motor learning and cognition: Clues from PET activation and lesion studies in man
TL;DR: The cerebellar output extends even to what has been characterized as the ultimate frontal planning area, the “prefrontal” cortex, area 46, and the cerebellum may be involved in context-response linkage, and response combination even at these higher levels.

A Theory of Cerebellar Cortex
TL;DR: A detailed theory of cerebellar cortex is proposed whose consequence is that the cerebellum learns to perform motor skills and two forms of input—output relation are described, both consistent with the cortical theory.

A Theory of Cerebellar Function
TL;DR: It is demonstrated that, in order for the learning process to be stable, pattern storage must be accomplished principally by weakening synaptic weights rather than by strengthening them.
