Visual event-related potential (P300): a normative study.
UNLABELLED The P300 component of the Event-Related Potential (ERP) is a general measurement of "cognitive efficiency". It is an index of the ability of an individual's Central Nervous System (CNS) to process incoming information. OBJECTIVE To develop a normative database for the visual P300. METHODOLOGY 30 right-handed individuals (same number of each sex), between 20 and 30 years of age, h...

UNLABELLED The P300 component of the event-related potential (ERP) is a general measurement of "cognitive efficiency". It is an index of the ability of an individual's central nervous system (CNS) to process incoming information. OBJECTIVE To compare the neuromodulatory effects of caffeine and bromazepam on the visual ERP (P300), in relation to a P300 normative database. METHOD 15 right-han...
متن کاملVisual event-related potentials to moving stimuli: normative data.
Visual cognitive responses (P300) to moving stimuli were tested in 36 subjects with the aim to find the normal range of P300 parameters. Concomitantly, the circadian intra-individual variability of the P300 was studied in a subgroup of 6 subjects. Visual stimuli consisted of either coherent (frequent stimulus) or non-coherent motion (random stimulus). The oddball paradigm was applied for record...
متن کاملBcis That Use P300 Event-related Potentials
27 of visual evoked potentials (i.e., VEPs) have been used as signal 28 features for BCIs. The design and operation of BCIs that use 29 endogenous ERP components differ both in principle and 30 practice from those of BCIs that use exogenous ERP compo 31 nents. This chapter focuses on BCIs that use P300, an endoge 32 nous ERP component. Chapter 14 discusses BCIs that use 33 exogenous VEP compo...
متن کاملEEG P300 event-related markers of hypnosis.
Barabasz, Barabasz, Jensen, Calvin, Trevisan, and Warner (1999) showed that, when subjects are stringently selected for hypnotizability and responses are time locked to events, robust markers of hypnotic responding emerge that reflect alterations in consciousness that correspond to subjects' subjective experiences of perceptual alteration. To further test the Barabasz et al. (1999) hypothesis, ...
