Jun 1, 2003 · Magnetoencephalography (MEG), a tool for describing spatial and temporal activity of the brain, is extremely useful in studies on P300 because, in contrast with the EEG [6], it can eliminate electrical signal interference by tissues surrounding the brain. In addition, MEG is able to produce precise estimations of the locations of ECDs.

The P300 (P3) wave is an event-related potential (ERP) component elicited in the process of decision making. It is considered to be an endogenous potential, as its occurrence links not to the physical attributes of a stimulus, but to a person's reaction to it.

Jan 1, 1998 · Based on recent research that indicated that P300 scalp topography varies as a function of task and/or information to be processed, this study examined scalp-recorded magnetic fields correlated with the P300 by means of whole-head magnetoencephalography.

Dec 1, 2023 · We showed that P300 is indeed linked to alpha rhythm, according to all four predictions. Our results provide an unifying view on the interdependency of evoked responses and neuronal oscillations and suggest that P300, at least partly, is generated by the modulation of alpha oscillations.

To assess the role of P300 in patients with temporal lobe epilepsy (TLE) with unilateral hippocampal sclerosis (HS) using magnetoencephalography (MEG) based auditory and visual oddball tasks, and to assess its correlation with neuropsychological tests.

Alternatively, the P300 response occurs at around 300ms in the oddball paradigm, for example, regardless of the type of stimulus presented: visual, tactile, auditory, olfactory, gustatory, etc.

Nov 20, 2020 · We used the P300 oddball auditory paradigm, known for its reduced amplitude in schizophrenia with AVH, and recorded high-density electroencephalography (HD-EEG, 256 channels), twice for each patient: pre-rTMS and 1 week post-rTMS treatment.

Our findings suggest that the thalamus plays an important role in generating P300 activity specific to color discrimination processing, and that in children the source is not consistent during development.

Purpose: To assess the role of P300 in patients with temporal lobe epilepsy (TLE) with unilateral hippocampal sclerosis (HS) using magnetoencephalography (MEG) based auditory and visual oddball tasks, and to assess its correlation with neuropsychological tests.

Changes in patterns of performance for the cognitive functions of memory, processing speed, and focused attention are expected in old age. The main goal of this systematic review was to analyze the use of ERP in healthy elderly in studies evaluating the P300 components.
