Stereotactic and functional neurosurgery
-
The use of functional neuroimaging holds the promise of improving neurosurgical outcomes by providing preoperative localization of critical brain functions. The brain representation of somatosensory function can be effectively localized using magnetoencephalography (MEG) in both normal subjects and in patients with tumors, vascular malformation, and epilepsy. This study investigates the pattern of somatosensory localization in 45 patients. ⋯ Results showed that this peak localized either to the central or postcentral sulcus of the somatosensory cortex. We found that neither age nor the presence of brain pathologies had significant effect on the recognition of the somatosensory cortex. Patients who underwent surgery after presurgical planning using MEG suffered no new somatosensory deficits, indicating the valuable role of pre-surgical mapping using MEG in the surgical planning.

Long-term efficacy of stereotactic bilateral anterior cingulotomy and bilateral anterior capsulotomy as a treatment for refractory obsessive-compulsive disorder.
To investigate the long-term efficacy and adverse effects of stereotactic bilateral anterior cingulotomy (BACI) and bilateral anterior capsulotomy (BACA) as a treatment for refractory obsessive-compulsive disorder (OCD) patients. ⋯ The BACI and BACA were effective for the treatment of refractory OCD, and no significant adverse effects on long-term follow-up were found.
