Functional recovery or sparing of function after damage to the brain has been a challenge to the doctorine of localization of function since it took over the view of mass action or equipotentiality. Several explanations such as 'diaschisis', 'vicarious function', 'hierarchical arrangement', 'behavioral substitution', or 'retraining' have since been offered, without anatomical and physiological foundation, to reconcile recovery and localization. In neurophysiological aspect, it is an unquestionable concept that the compensatory function of the brain can be ascribed to plastic changes in synaptic transmission or neuronal connection or both. Electrophysiological and morphological studies of recent years provided evidence for the occurrence of such changes during recovery after damage to the brain, although causal relation between each change and behavioral recovery is generally unclear. This article attempts to give some insight in the mechanisms of compensatory function from the standpoint of neurophysiology and neuroanatomy by reviewing reorganization of neuronal circuitries mainly in the cerebellum and related structures.
