Transitive movements in a deafferented man.
It has not been determined if the performance of transitive movement requires sensory feedback from the limb to the brain. We tested a deafferented patient's ability to pantomime, imitate, and use actual objects in both eyes open and eyes closed conditions. Although his performance deteriorated when his eyes were closed, the major error made by this patient was the inability to correctly orient the instrument (or pretended instrument) toward the object of the instrument's action.
