Identification of a negative bitemporal component (N300) of the event-related potentials demonstrated by noncephalic recordings.
We studied the scalp distribution of auditory event-related potentials (P300), using simultaneously a cephalic (linked ears) and a noncephalic (balanced sternovertebra) reference. The recordings with noncephalic reference showed that infrequent, attended auditory stimuli evoke a negative bitemporal component (N300) as well as a positive vertex component (P300).
