Ultra high-density, 4096-channel intraoperative neurophysiological brain mapping for functional localization of the human central sulcus.
OBJECTIVE Intraoperative localization of the central sulcus (CS) using somatosensory evoked-potential (SSEP) phase reversal is routinely performed with sparse subdural strip electrodes. We evaluated whether a multi-array, 4096-channel surface micro-electrocorticography (μECoG) configuration could provide dense two-dime...
