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