Event-related potential (P300) in epilepsy

Acta Neurologica Scandinavica, 1990
The P300 component of auditory event-related potential was studied in 39 patients with temporal lobe epilepsy (TLE), 26 with idiopathic generalized epilepsy (IGE) and 28 controls. The age-corrected P300 latencies were significantly longer in TLE patients compared with those in IGE patients and controls.

P300 Event-Related Potentials in Epileptic Children

Clinical Electroencephalography, 1994
To evaluate the cognitive function of epileptic children, we examined P300 in 50 patients, 32 with idiopathic generalized epilepsy (IGE) and 18 with temporal lobe epilepsy (TLE), and 39 normal children. There were significant negative correlations between age and P300 latencies at Pz and Cz in normal controls.

Event-related potentials (P300) in myotonic dystrophy

Acta Neurologica Scandinavica, 1989
The P300 component of the auditory event-related potential in 8 patients with myotonic dystrophy was studied and compared with that of 13 healthy controls. Abnormalities of P300 (prolongation of the latency and/or decrease of the amplitude) were observed in 6.

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

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).

Cerebrovascular accident alters P300 event-related potential characteristics

Electroencephalography and Clinical Neurophysiology, 1986
P300 event-related potentials to counted (target) and uncounted (background) visual stimuli were recorded from subjects who had sustained either a right or a left middle cerebral artery cerebrovascular accident (CVA) and from appropriate normal control subjects. Subjects were asked to count target stimuli and to ignore non-target stimuli.

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.
