Automated intraoperative central sulcus localization and somatotopic mapping using median nerve stimulation

Abstract: Objective: Accurate identification of functional cortical regions is essential in neurological resection. The central sulcus (CS) is an important landmark that delineates functional cortical regions. Median nerve stimulation (MNS) is a standard procedure to identify the position of the CS intraoperatively. In this paper, we introduce an automated procedure that uses MNS to rapidly localize the CS and create functional somatotopic maps. Approach: We recorded electrocorticographic signals from 13 patients who und… Show more

“…Moving posteriorly to channels 209, 210, 212, and 215, which are expected to be located posterior to the central sulcus, the waveform reflects a P followed by the N peak, which aligns with the literature 3 , 24 . Similar to the posterior channels, slight SSEP timing and amplitude variations are observed.…”

“…Intraoperatively neurophysiology (ION) techniques are the gold standard for monitoring brain function and spatial mapping of brain areas. During surgery, procedures for generating somatosensory evoked potentials (SSEPs) are often carried out as they provide essential spatial information about the somatosensory cortex and the central sulcus (CS) 3 , 23 , 24 . Mainly, they are used to prevent any postoperative neurological deficits due to the resection of functional anatomical regions 25 .…”
