Cerebellar learning of internal models for reaching and grasping: adaptive control in the presence of delays

The cerebellum provides a paradigm for motor control in which adaptive circuitry modulates control systems rather than being embedded within the motor control circuitry itself. We exemplify this by a model of the role of cerebellum in adaptation to the effects of wearing prism glasses on throwing at a target. The cerebellum is viewed as a set of modules (cerebellar microcomplexes), each of which can be added to a control system to improve smooth coordinated movement, with improvements continuing and improving over time. Moreover, context information can be injected into a module which enables it to change modes. We close with a brief discussion of the implications of work on cerebellar modeling, noting that cerebellar modules can be linked to coordinate different control systems.
