P300 Component of Event-Related Potentials in Passive Tasks
International Journal of Neuroscience, 1996Auditory 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 ...

Correlations between P300 Components and Neurotransmitters in the Cerebrospinal Fluid
Clinical Electroencephalography, 1998P300 and cerebrospinal fluid neurotransmitter metabolites and amino acids were examined in 10 patients with Alzheimer's disease, 9 patients with vascular dementia and 10 healthy controls. A negative correlation between P300 amplitude and MHPG concentration, negative correlation between P200 and N200 latencies and norepinephrine concentration, positive ...

Spectral components of the P300 speller response in and adjacent to the hippocampus
2012 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2012Recent studies have demonstrated that the P300 Speller can be used to reliably control a brain-computer interface via stereotactic depth electrodes (SDEs) implanted in and adjacent to the hippocampus. The superior bandwidth and spatial resolution of intracranial signals compared to scalp electroencephalography (EEG) may provide better insight into the ...

Components in the P300:Don’t forget the Novelty P3!
Psychophysiology, 2019AbstractThis study investigated stimulus‐response patterns of temporal principal components analysis (PCA)–derived event‐related potential (ERP) components in a classical auditory habituation paradigm with long interstimulus intervals. The skin conductance response (SCR) was included as the “gold standard” model of the Orienting Reflex.

The P300 component of event-related potentials in schizophrenic patients
Revue d&'apos;Electroencéphalographie et de Neurophysiologie Clinique, 1987In 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 ...

Abnormalities in P300 components in depression: an ERP-sLORETA study
Nordic Journal of Psychiatry, 2019Alterations in P300 components occur in depressed patients, but the brain regions contributing to these changes remain unclear.Thus, the aim of the present study was to examine the underlying neural activation of P300 components in patients with depression to explore brain regions related to depression.P300 components were evoked by an oddball auditory

The late positive component (P300) and information processing in sentences
Electroencephalography and Clinical Neurophysiology, 1975Averaged visual evoked potentials to sequentially flashed words comprising a sentence were recorded from vertex and left and right temporoparietal electrodes in 8 right-handed subjects. In condition 1 the sentence took the form: The -eel is on the shoe, in which the first grapheme was omitted from the second word, so that the subject did not know the ...

N200 and P300 component changes in Parkinson’s disease: a meta-analysis
Neurological Sciences, 2022Cognitive impairment can seriously affect the quality of life of Parkinson's disease (PD) patients. Although numerous studies showed that N200, P300 latency and amplitude are correlated with cognitive functions, there is a sufficient amount of controversial results.

Spectral components of the P300 speller response in electrocorticography
2011 5th International IEEE/EMBS Conference on Neural Engineering, 2011Recent studies have demonstrated that the P300 Speller can be used to reliably control a brain-computer interface via scalp-recorded electroencephalography (EEG) and intracranial electrocorticography (ECoG). However, the exact reasons why some disabled individuals are unable to successfully use the P300 Speller remain unknown.

p300, and p300-associated proteins, are components of TATA-binding protein (TBP) complexes.
Oncogene, 1993The transforming proteins encoded by the adenovirus E1A gene bind to a 300-kDa cellular product, p300, via the N-terminal E1A sequences. Residues important for p300 binding are required for the transformation function of E1A and for other E1A-mediated gene-regulating functions, including activation of cell cycle-regulated products and repression of ...
