Representative somatosensory-evoked responses. A Superimposed SSEPs and corresponding topography at 12, 18, and 24 ms for patient 1. B Early (9–18 ms) and late (18 and 24 ms) activation for patient 1 mapped onto her MRI. C Superimposed SSEPs and corresponding topography at 13, 18, and 24 ms for patient 2. D Early (9–18 ms) and late (18 and 24 ms) activation for patient 2 mapped onto her MRI. Stim., stimulus; L, left; R, right; A, anterior; P, posterior
