Positron emission tomography imaging-directed stereotactic neurosurgery.

abstract：:Subacute and chronic continuous electrical stimulation at the epileptic focus in the hippocampus or parahippocampal cortex at 130 Hz, 0.21-1.0 ms, 2.5-3.5 V (about 200-300 microA) induces a decrease in focal EEG epileptic interictal activity and also in the occurrence of clinical seizures. This may represent an altern...
