title: Contralateral and ipsilateral control of fingers following callosotomy.
abstract: The extent of ipsilateral control of the distal limbs is not documented. In this experiment visuo-motor control of fingers was investigated in two callosotomy patients. A substantial amount of ipsilateral control was evident, especially for the left hand fingers. Ipsilateral control of the right hand was evident for the thumb and index fingers, but not for the other fingers. Left hand fingers did not vary significantly in degree of ipsilateral control.
