Abstract

The present authors recently examined the motor and cognitive functions in a right-handed male patient (J.S.) with transection of the anterior two-thirds of the cerebral corpus callosum. Among the functions examined was the patient’s ability to acquire and retain the tactuo-spatial motor learning required for mastery of finger maze tasks (Figure 1). It was observed that even though J.S. demonstrated better acquisition performance with his nondominant left hand, transfer of learning to an identical maze from that hand to his dominant right was less efficient than transfer in the opposite direction (Table 1). Patient J.S.’s findings, in conjunction with results from a study investigating finger maze acquisition and transfer in intact subjects (Ward et. al., 1987), served as the basis for a preliminary functional model for cerebral cortical areas and information pathways that might be involved in tactuo-spatial finger maze learning and performance.
