Event related evoked potential P300 in frontotemporal dementia

Neurobiology of Aging, 2000
There are no studies on event-related cognitive potentials in frontotemporal dementia (FTD). In order to evaluate the aptitude and usefulness of the event-related P300 potential in this disease, we prospectively examined 60 cases: 11 patients with FTD diagnosed according to the Lund and Manchester criteria and Neary consensus criteria, 33 patients with

P300 Component of Event-Related Potentials in Passive Tasks

International Journal of Neuroscience, 1996
Auditory P300 components were recorded in two kinds of passive tasks (a sequence task and a novel task) and were compared to that in a standard oddball task. The P300, the amplitude of which was largest at Pz, was elicited in the two passive tasks. The P300 amplitude in the two passive tasks was not significantly smaller than that in the oddball task ...

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

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 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 ...

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).

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.

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.
