Non-invasive single-trial detection of variable population spike responses in human somatosensory evoked potentials

Non-invasive electroencephalography during peripheral nerve stimulation provides functional information about central stimulus processing. In particular, the clinically established low-frequency EEG (<100Hz) mainly reflects cortical postsynaptic potentials, i.e., the input of neuronal computation (Okada et al., 1997). In contrast, somatosensory evoked potentials (SEPs) contain an additional oscillatory high-frequency EEG burst (≈600Hz), denoted here as 'σ-burst', which is concomitant with the first cortical low-frequency component (the post-synaptically generated 'N20' for median nerve stimulation) and can be isolated by high-pass filtering above 400 Hz (Cracco and Cracco, 1976; Eisen et al., 1984).
