Neural Correlates of Knowledge: Stable Representation of Stimulus
... with a cue stimulus (e.g., a rain cloud). The cue is followed by presentation of two choice stimuli, from which the subject must identify the stimulus that has been paired with the cue (e.g., an umbrella). To perform correctly the subject must access their knowledge of the stimulus pairing at some t ...

... component properly includes its "scalp distribution" (i.e. the pattern of relative amplitudes the component has across all recording sites). The "latency" of a peak is usually defined as the time point where the component reaches its largest amplitude. Thus a frequent convention for labelling peaks ...

Contributions of temporal-parietal junction to the human
... to temporal dispersion of the P3, since no P3 was observed to subaverages of correctly detected stimuli with the fastest RTs and smallest R T variance in the temporal group (block 4, Expt. 1 = 489 + 63 ms). Similar results were obtained in Expt. 2. P3b and P3a amplitudes at Pz were comparable for co ...

Responses to Rare Visual Target and Distractor Stimuli Using Event
... Previous studies have found that the P300 or P3 event-related potential (ERP) component is useful in the diagnosis and treatment of many disorders that influence CNS function. However, the anatomic locations of brain regions involved in this response are not precisely known. In the present event-rel ...

Visually Induced Ocular Torsion
... visual scene enriched with spatial clues important for maintaining posture was found to induce significantly more torsion compared to a scene without spatial clues. The degree of stimuli tilt had no significant effect, nor the stimuli periphery. In the second study, torsional response was shown to d ...

A simultaneous ERP/fMRI investigation of the P300 aging effect
... distractors could be as high as 64 seconds. The average was approximately 20 seconds, and approximately 70% of trials occurred between 8 and 22 seconds. All stimuli were presented on a gray background and participants were asked to maintain fixation on a white cross presented at the center of the sc ...
