Human cerebellar activity reflecting an acquired internal model of a new tool

Article Abstract:

It is possible that the cerebellum aids information processing in cerebral areas by supplying general internal models of extended controlled objects in the external world. Research involving human subjects learning to use a computer mouse with a novel rotational transformation indicated that two types of activity were involved. One was spread over wide areas of the cerebellum and was exactly proportional to the error signal that determines the acquisition of internal models during learning. The other was restricted to the area near the posterior superior fissure.

Internal model visualized

Article Abstract:

It has been possible to obtain a set of brain-imaging data that give the first evidence for motor learning model formation in the cerebellum. The internal-model concept for motor learning is reasonable if the known cellular mechanisms of the cerebellum are taken into account. The success of this research in visualizing an internal model in the cerebellum should provide valuable impetus to those working on ways of experimentally investigating computational and cognitive principles of the brain.

Body image as a visuomotor transformation device revealed in adaptation to reversed vision

Article Abstract:

Research is presented concerning the ability of individual people to adapt rapidly to visual field reversals which have been caused by prism spectacles. Visuomotor mapping is discussed.
