Retinal Information

The cerebellar cortex is a crystal-like structure consisting of an almost endless repetition of a canonical microcircuit that applies the same computational principle to different inputs. The output of this transformation is broadcasted to extracerebellar structures by way of the deep cerebellar nuclei. Visually guided eye movements are accommodated by different parts of the cerebellum. This review primarily discusses the role of the oculomotor part of the vermal cerebellum [the oculomotor vermis (OMV)] in the control of visually guided saccades and smooth-pursuit eye movements. Both types of eye movements require the mapping of retinal information onto motor vectors, a transformation that is optimized by the OMV, considering information on past performance. Unlike the role of the OMV in the guidance of eye movements, the contribution of the adjoining vermal cortex to visual motion perception is nonmotor and involves a cerebellar influence on information processing in the cerebral cortex.

Kinesthetic Feedback

Hooded rats were pre-exposed to circles and triangles in an otherwise visually sparse environment where opportunity to manipulate the forms was varied for the early experience groups. Although early experience with these stimuli enhanced their later discriminability over that shown by control animals who received no early experience, opportunity to manipulate the forms produced no additional gain in perceptual learning relative to Ss not allowed to manipulate the pre-exposed shapes. The findings restrict the generality of the tactual-kinesthetic feedback hypothesis.
