Abstract
Somatosensory evoked fields (SEFs) following median nerve stimulation can be recorded from the contralateral primary sensorimotor cortex (SMI), from the second somatosensory cortex (SII) bilaterally and from contralateral posterior parietal cortex (PPC) [1],[2]. At SMI, the response can be divided into distinct N20m, P35m and P60m deflections, while SII responses are biphasic with peaks at 80–100 ms and about 150 ms. The latency of the PPC response is usually 80–100 ms.
