TL;DR: Electrical stimulation mapping with currents below the threshold of afterdischarges showed somatotopic organization of supplementary motor cortex with the lower extremities represented posteriorly, head and face most anteriorly, and the upper extremities between these two regions.

TL;DR: The anatomic generators of human median nerve somatosensory evoked potentials were investigated in 54 patients by means of cortical-surface and transcortical recordings obtained during neurosurgery and suggest that the ipsilateral potentials are generated by transcallosal input from the contralateral hemisphere.

TL;DR: These results provide the first direct evidence that the detrimental effect of emotional distracters on ongoing cognitive processes entails the interaction between a dorsal neural system associated with “cold” executive processing and a ventral system associatedwith “hot” emotional processing.

TL;DR: Current knowledge of SEPs generated in cerebral cortex by stimulation of the median nerve is summarized, with the conclusion that these potentials are generated in contralateral somatosensory cortex in areas 3b and 1, in contrast to the conclusion of many previous studies that SEPs recorded from the frontal scalp aregenerated in motor cortex and other frontal lobe areas.

TL;DR: The results suggest that discrete regions of inferior extrastriate visual cortex, varying in location between individuals, are specialized for the recognition of faces.
