Abstract

We used intrinsic signal optical imaging to obtain maps of human somatosensory cortex during electrocutaneous stimulation of the face during a neurosurgical procedure for epilepsy. We found that human face somatotopy is organized like the macaque or cebus monkey, with peri-orbital skin located medial to peri-buccal skin, and that cortical magnification in the human is comparable to that in non-human primates. This study demonstrates that intrinsic signal imaging can be performed on humans during operative procedures with sufficient spatial resolution to reveal high-resolution topographic maps.
