• P300 event-related brain potentials (ERPs) were recorded using auditory stimuli from 8 patients with confirmed left (4) or right (4) unilateral damage to the temporo-temporal junction. 6 normal control subjects were matched to each patient with respect to age and sex. P300 latency, but not amplitude, shows significant differences between control and pathologic groups. This kind of results does not permit to establish critical relations between temporo-parietal junction and P300 generators.
