BIS/BAS Sensitivity and the P300 Event-Related Brain Potential

Journal of Psychophysiology, 2007
Abstract. Both a reduced amplitude of the P300 event-related potential component and a highly impulsive personality are known to be strong predictive markers for substance abuse and related psychiatric disorders. Because of this common link to externalizing psychopathology, a significant negative association between the P300 amplitude and personality ...

Clinical application of the P300 event-related brain potential

Physical Medicine and Rehabilitation Clinics of North America, 2004
The P300 brain potential can provide information about cognition that is quantitatively comparable to other clinically used biomedical assays. Causes of P300 variability with respect to task and biologic determinants have been well characterized so that refinement of ERP methods for clinical applications is possible.

The P300 Wave of the Human Event-Related Potential

Journal of Clinical Neurophysiology, 1992
The P300 wave is a positive deflection in the human event-related potential. It is most commonly elicited in an "oddball" paradigm when a subject detects an occasional "target" stimulus in a regular train of standard stimuli. The P300 wave only occurs if the subject is actively engaged in the task of detecting the targets. Its amplitude varies with the

Classification of P300 event related potentials with Discrete Wavelet Transform

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
Brain Computer Interfaces (BCIs) are the systems that enable users who lost their motor capabilities due to neuromuscular diseases to communicate with their environment through the analysis of brain activity. P300 event related potential is one of the widely used signals in BCI applications.

Reprint of: Stuttering treatment control using P300 event-related potentials

Journal of Fluency Disorders, 2011
Positron emission tomography studies during speech have indicated a failure to show the normal activation of auditory cortical areas in stuttering individuals. In the present study, P300 event-related potentials were used to investigate possible effects of behavioral treatment on the pattern of signal amplitude and latency between waves.

P300 event‐related potential heritability in monozygotic and dizygotic twins

Psychophysiology, 1997
AbstractThe present study examined the heritability of the P3 waveform and the N1, P2, and N2 components by assessing the visual event‐related potential (ERP) of 30 monozygotic (MZ) and 34 dizygotic (DZ) twin pairs. Electroencephalogram activity was recorded from Pz, P3, and P4 scalp sites while individuals performed a reaction time task involving two ...

P300 event-related potential in euthymic patients with bipolar disorder

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2009
Auditory P300 event-related potential (ERP) and performance on Sustained Attention were evaluated in 24 euthymic bipolar patients and 38 healthy volunteers. There were no significant differences between groups, and performance in sustained attention had no significant influence in the P300 responses.

Wavelet Filtering of the P300 Component in Event-Related Potentials

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
This paper presents an application of wavelet filtering to single-trial P300 component analysis. The objective of this study is to introduce a new method for analyzing the P300 component, when performing a given cognitive task, in this case, a two-choice reaction time task.

P300 event-related potentials and cognitive function in social phobia

Psychiatry Research: Neuroimaging, 2004
The aim of the study was to investigate abnormalities of event-related potentials (ERPs) in social phobia patients indicating deficits in speed and amount of perceptual and cognitive resources as well as relationships between ERPs and cognitive functioning.

Effects of Self-Evaluation on the P300 Event-Related Potential

Perceptual and Motor Skills, 2005
The effects of self evaluation on the P300 event-related potential (ERP) were explored with 56 participants (16 men, 40 women; M age = 23.4 yr., SD = 1.2) across three conditions. The conditions included (1) a standard ERP auditory oddball discrimination between a random target (15% occurrence) and standard stimuli (85% occurrence), (2) the oddball ...
