14-year-old male with intractable seizure and previous right frontal lobectomy status. Selective callosotomy was planned because patient complained of repeated seizure attacks. Yellow fibers indicate commissural fibers between bilateral sensory-motor cortex, which were preserved after callosotomy, while other callosal fibers were disconnected (thick arrow at frontal fibers and thin arrows at splenial fibers).
