Med SN - 09607560 KW - Stimulus-response interval KW - P3 waveform KW - oddball KW - movement N2 - A cognitive potential called P3 wave was tested as a possible reflection of movement triggering processes. Target and non-target visual stimuli were presented to 14 epileptic patients during the standard visual oddball task. A microswitch button was pressed in response to every target stimulus. The intracerebral EEG signal was obtained from various sites of the brain. Correlation between the P3 peak latency and the SRI was calculated for each site. Two main types of P3 waves were found: A type with no correlation, 79 sites (61%) of all 14 subjects; B type with a statistically significant correlation (p<0.01, r=1), 30 sites (23%) of 9 subjects. The rest of P3 waves revealed an ambiguous degree of correlation. We showed that the peak latency of some P3 waves correlated with the SRI and thus, were temporally linked to the movement onset. We suggest that some neuronal processes represented with the P3 waves are somehow engaged in the movement triggering. ER -
