Paw-reaching, sensorimotor, and rotational behavior after brain infarction in rats.

Abstract

In contrast to amphetamine-induced rotation and sensorimotor behavior, the paw-reaching test provides a stable behavioral parameter after a middle cerebral artery occlusion. Moreover, the lesion-induced deficit in paw-reaching is highly correlated to the extent of the infarct, suggesting that this test is useful in evaluating treatment effects for a longer period of time.
