The P300 component of event-related potentials in schizophrenic patients

Revue d&'apos;Electroencéphalographie et de Neurophysiologie Clinique, 1987
In a pilot study, the P300 component of the ERP subsequent to competitive visual stimulation was examined in 12 schizophrenic patients (paranoid hallucinatory schizophrenia in partial remission, neuroleptic medication). In the competitive stimulation with a varying information content of the non-target stimuli, healthy probands showed a distinct ...

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 ...

Auditory P300 event-related potential in tobacco smokers

Journal of Clinical Neuroscience, 2009
The aim of this study was to elucidate the chronic effects of tobacco smoking on the P300, a neurophysiological index of cognitive function. Prospective study participants were recruited from a family medicine polyclinic. We selected 32 right-handed smokers who had smoked more than 15 cigarettes per day, by inhalation, for more than 2 years.

THE P300 EVENT RELATED POTENTIAL COMPONENT IN THE DIAGNOSIS OF DEMENTIA

Australian and New Zealand Journal of Medicine, 1988
AbstractSeveral studies have suggested that delays in the latency of the P300 ERP component are highly sensitive and specific to dementia and that ERP measurements may become a useful clinical tool in aiding diagnosis. This study examines the sensitivity of P300 measurements to dementia and addresses several methodological issues that limit previous ...

Auditory event-related potentials (P300) in epileptic patients

Neurophysiologie Clinique/Clinical Neurophysiology, 2001
Auditory event-related potentials (AERPs) were recorded during an auditory oddball paradigm in 108 epileptics and in 32 healthy controls. P300 latency varied in relationship with age only in controls. Symptomatic epileptics had significantly prolonged P300 mean latency compared to those without detectable brain lesion(s) on MR scan.

Slow Movement Execution in Event-Related Potentials (P300)

Perceptual and Motor Skills, 2002
We examined whether slow movement execution has an effect on cognitive and information processing by measuring the P300 component. 8 subjects performed a continuous slow forearm rotational movement using 2 task speeds, Slow (a 30–50% decrease from the subject's Preferred speed) and Very Slow (a 60–80% decrease).

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.

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.

An application of the P300 event-related potential as a biometric

2014 40th Annual Northeast Bioengineering Conference (NEBEC), 2014
The use of brain wave patterns as a biometric is highly resistant to fraud. The ease of collecting P300 event-related potentials from most subjects also makes it a potential biometric for the general public. This paper proposes a method to use topological plots typical to the study of P300 as a biometric in individual identification and authentication.

Effect of transcranial magnetic stimulation on P300 of event-related potential

2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
When the odd stimulation is presented, the positive component of electroencephalograph is induced at around 300 ms after the odd stimulation. This positive component is called P300. Many studies suggest that P300 may result from the summation of activity from multiple generators located in widespread cortical and subcortical areas.
