Event-related potentials (P300) in myotonic dystrophy
Acta Neurologica Scandinavica, 1989The 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.

Wavelet Filtering of the P300 Component in Event-Related Potentials [PDF]
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006 This paper presents an application of wavelet filtering to single-trial P300 component analysis. The objective of this study is to introduce a new method for analyzing the P300 component, when performing a given cognitive task, in this case, a two-choice reaction time task.

On the neural generators of the P300 component of the event‐related potential
Psychophysiology, 1993AbstractThe triarchic model of P300 amplitude (Johnson, 1986, 1988a) postulated that the overall amplitude of the P300 recorded at any given electrode site represented the summation of activity from different neural generators, each related to the processing of a different type of information.

BCIs That Use P300 Event-Related Potentials [PDF]
, 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.

BIS/BAS Sensitivity and the P300 Event-Related Brain Potential
Journal of Psychophysiology, 2007Abstract. Both a reduced amplitude of the P300 event-related potential component and a highly impulsive personality are known to be strong predictive markers for substance abuse and related psychiatric disorders. Because of this common link to externalizing psychopathology, a significant negative association between the P300 amplitude and personality ...

No Effect of Chronic Fenfluramine on the P300 Component of the Event-Related Potential
International Journal of Neuroscience, 1987Five autistic children were administered a visual version of the oddball paradigm under both drug (chronic fenfluramine) and placebo conditions. The P300 component of the event-related potential (ERP) was not affected by fenfluramine, although the drug significantly lowered blood concentrations of serotonin.

P300 Event-Related Potentials in Stutterers and Nonstutterers
Journal of Speech, Language, and Hearing Research, 1997This 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, 2016To 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.

P300 Event-Related Potentials in Epileptic Children
Clinical Electroencephalography, 1994To 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.
