Neural Correlates of Knowledge: Stable Representation of Stimulus
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 ...

... 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 ...

... 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 ...

P3b

The P3b is a subcomponent of the P300, an event-related potential (ERP) component that can be observed in human scalp recordings of brain electrical activity. The P3b is a positive-going amplitude (usually relative to a reference behind the ear or the average of two such references) peaking at around 300 ms, though the peak will vary in latency (delay between stimulus and response) from 250-500 ms or later depending upon the task. Amplitudes are typically highest on the scalp over parietal brain areas.The P3b has been a prominent tool used to study cognitive processes for several decades. More specifically, this ERP component has played a key role in cognitive psychology research on information processing. Generally speaking, improbable events will elicit a P3b, and the less probable the event, the larger the P3b. However, in order to elicit a P3b, the improbable event must be related to the task at hand in some way (for example, the improbable event could be an infrequent target letter in a stream of letters, to which a subject might respond with a button press). The P3b can also be used to measure how demanding a task is on cognitive workload.
