Somatosensory cortical responses. (A) HD-EEG cap (64 channels) on the head of a patient with SSADHD (patient #1); (inlet panel) pneumatic stimulators attached to the distal, volar parts of the patient’s four digits (i.e. thumb, index, middle finger, and pinky). (B) Relative location of HD-EEG electrodes with respect to patient’s scalp and cortex (upper panel), and location of the virtual channel placed contralateral to the stimulation site’s primary somatosensory cortex (S1) (lower panel). (C) Averaged somatosensory-evoked cortical responses for all digits for this patient (upper panel) in μV and cortical responses (absolute values) at the virtual channel in contralateral S1.
