We present the first EIT images of evoked physiological activity in the primary somatosensory cortex (S1) obtained with intracranial planar electrode array. Images were validated using intrinsic signal optical imaging (ISOI) and current source-sink density analysis (CSDA). Detailed high-resolution spatiotemporal connectivity of the brain cortex was reconstructed with ≤200μm and ≤2ms.
