P300 amplitude is insensitive to working memory load in schizophrenia

BMC Psychiatry, 2011
Background Working memory (WM) tasks usually elicit a P300 ERP component, whose amplitude decreases with increasing WM load. So far, this effect has not been studied in schizophrenics (SZs), a group that is considered to have an aberrant brain ...

Real-time feature extraction of P300 component using adaptive nonlinear principal component analysis

BioMedical Engineering OnLine, 2011
Background The electroencephalography (EEG) signals are known to involve the firings of neurons in the brain. The P300 wave is a high potential caused by an event-related stimulus.

p300 is a component of an estrogen receptor coactivator complex. [PDF]

Proceedings of the National Academy of Sciences, 1996
The estrogen receptor (ER) is a ligand-dependent transcription factor that regulates expression of target genes in response to estrogen in concert with other cellular signaling pathways. This suggests that the mechanism by which ER transmits an activating signal to the general transcription machinery may include factors that integrate these diverse ...

Enhanced effective connectivity from the middle frontal gyrus to the parietal lobe is associated with impaired mental rotation after total sleep deprivation: An electroencephalogram study

Frontiers in Neuroscience, 2022
Sleep deprivation impairs cognitive functions, including attention, memory, and decision-making. Studies on the neuro-electro-physiological mechanisms underlying total sleep deprivation (TSD) that impairs spatial cognition are limited.

Test-Retest Reliability of ERP and Auditory Steady State Response in Patients With Disorders of Consciousness

IEEE Transactions on Neural Systems and Rehabilitation Engineering
To identify the optimal auditory evoked strategy for assessing the level of consciousness in patients with disorders of consciousness (DoC) based on event related potentials (ERP) and amplitude modulation auditory steady state response (ASSR) and its ...

An N100-P300 Spelling Brain-Computer Interface with Detection of Intentional Control

Computers, 2016
A brain-computer interface (BCI) is a tool to communicate with a computer via brain signals without the user making any physical movements, thus enabling disabled people to communicate with their environment and with others. P300-based ERP spellers are a

Systematic review and meta-analysis of late auditory evoked potentials as a candidate biomarker in the assessment of tinnitus.

PLoS ONE, 2020
Subjective tinnitus, the perception of sound in the absence of any sound source, is routinely assessed using questionnaires. The subjective nature of these tools hampers objective evaluation of tinnitus presence, severity and treatment effects.

3D Input Convolutional Neural Networks for P300 Signal Detection

IEEE Access, 2020
P300 signal is an endogenous event related potential component. It is mostly elicited from the frontal to parietal brain lobes. Electroencephalography is used for acquiring P300 signal from scalp. P300 signal is used for brain-computer interface systems.
