=====Limbic surgery===== The surgical targets that are utilized vary across institutions and involve lesions produced bilaterally in the anterior limb of the internal capsule ([[anterior capsulotomy]]), the supragenual anterior cingulate gyrus and cingulum (anterior cingulotomy), and the subgenual anterior cingulate gyrus and subcortical orbitofrontal white matter (subcaudate tractotomy) ((Greenberg BD, Price LH, Rauch SL, et al: Neurosurgery for intractable obsessive-compulsive disorder and depression: critical issues. Neurosurg Clin N Am 2003; 14:199–212)) ((Cosgrove GR, Rauch SL: Psychosurgery. Neurosurg Clin N Am 1995; 6:167–176)). The combination of bilateral cingulotomy and subcaudate tractotomy is known as limbic leucotomy
