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.

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.

On the value of P300 Event-Related Potentials in the Differential Diagnosis of Dementia

British Journal of Psychiatry, 1984
SummaryThe possible value of event-related potentials (ERPs) in the differential diagnosis of dementia was investigated in a group of 42 demented elderly patients, 29 non-demented elderly patients, and 10 healthy young controls. The auditory evoked potentials were elicited by using target and non-target auditory stimuli.

P300 Component of Event-Related Potentials in Persons With Asperger Disorder

Journal of Clinical Neurophysiology, 2014
In the present study, we investigated auditory event-related potentials in adults with Asperger disorder and normal controls using an auditory oddball task and a novelty oddball task. Task performance and the latencies of P300 evoked by both target and novel stimuli in the two tasks did not differ between the two groups.

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.

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 ...

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.

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.

P300 event-related potentials in probable dissociative generalized amnesia

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 1999
1. To investigate whether abnormalities in objective neurophysiologic measures are observable in patients with probable dissociative generalized amnesia, the P300 and N100 event-related potentials were evaluated in six such patients in both acute stage and after recovery from amnesia.

The effect of jogging on P300 event related potentials.

Electromyography and clinical neurophysiology, 1999
Physical exercise has beneficial effects not only on cardiovascular system and fat metabolism, may also directly effect the cognitive process. We studied the effect of physical exercise on cognitive processes by measuring the P300 event related-potential (ERP) after jogging. Seven well-trained joggers were enrolled in this study and the P300 potentials
