[The characteristics of the recovery of the manipulative habit in white rats depending on the side of the neocortical damage and of the initial motor preference].

It was shown that unilateral lesions of the left and right sensorimotor cortex in male Wistar rats led to similar deficit in manipulatory ability to perform the reaching task. Recovery rate depended on the side of lesion, i.e., damage of the right hemisphere was compensated sooner than that of the left one. This difference was significant in ambidextrous rats while in sinistrals and dextrals it was not pronounced.
