Abstract
The present study reports on a 23-year-old male patient with somatosensory dysfunction of the left hand following cortical contusion. His somatosensory dysfunction recovered to a nearly normal state at 6 months after injury. Functional MRI results demonstrated that the contralateral primary sensorimotor cortex centered on the primary somatosensroy cortex was activated during touch stimulation of the patient's right hand and either hand of control subjects. By contrast, the anterior area of the lesion centered on the precentral knob in the right hemisphere was activated during touch stimulation of the left hand. These findings show that the somatosensory function of the affected hand appears to have been recovered by the somatosensory cortex reorganizing into the anterior area of the contused primary somatosensory cortex.
