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.

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 Potentials in Stutterers and Nonstutterers

Journal of Speech, Language, and Hearing Research, 1997
This study investigated possible differences between adult stutterers and nonstutterers in the P300 event-related potential. Responses to tonal stimuli were recorded from electrodes placed over the left (C3) and right (C4) hemispheres. The two groups exhibited different patterns of interhemispheric activity.

P300 event-related potentials in children with dyslexia

Annals of Dyslexia, 2016
To elucidate the timing and the nature of neural disturbances in dyslexia and to further understand the topographical distribution of these, we examined entire brain regions employing the non-invasive auditory oddball P300 paradigm in children with dyslexia and neurotypical controls.

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.

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 ...

P300 event-related potential in abstinent methamphetamine-dependent patients

Physiology & Behavior, 2015
Substance use and abuse are characterized by biases in the attentional processing of substance-related stimuli. There are no event related potential (ERP)-based studies of attentional bias for substance-related cues among methamphetamine (MA) dependent patients.

BCIs That Use P300 Event-Related Potentials

2012
Event-related brain potentials (ERPs) in electroencephalography are manifestations at the scalp of neural activity that is triggered by, and is involved in, the processing of specific events. This chapter focuses on brain-computer interfaces (BCIs) that use P300, an endogenous ERP component.

Seizure frequency affects event-related potentials(P300) in epilepsy

Journal of Clinical Neuroscience, 2001
To analyse the effect of epilepsy an P300 event-related potentials we studied 27 patients with idiopathic generalized epilepsy (IGE), 13 patients with temporal lobe epilepsy (TLE) and 60 normal controls. The prolongation of P300 latencies was highly cor related with increasing age in controls but not epileptic patients.

Long latency event-related potentials (P300) in gifted children

Brain and Development, 1993
In children, P3 latency decreases with increasing age. This decrease could be linked with the maturation of cognitive processes. According to this hypothesis, event-related potentials P3 were recording in gifted children to research an electrophysiological correlation with the mental precocity.
