Intraoperative Brain Microdialysis to Assess Neuroinflammation in Epileptic Tissue Immediately Prior to Surgical Resection.

Our current standard practice is to use a lateral approach through the middle temporal gyrus to place 3 depth electrodes targeting the hippocampus for intraoperative verification of pathological epileptiform activity prior to resection. Our research protocol will add one FDA approved electrode that has a central cannula for insertion of a microdialysis probe.
