EEG-P300 Potential in Methadone Subjects based on Parietal and Frontal Channels with Different Image Stimulus

SummaryEleven retired sportsmen, who had a career in contact sports (three boxers, four footballers, four wrestlers) and one cyclist with a history of several falls from a bicycle and had been diagnosed with a cerebrovascular trauma, were investigated with auditory cognitive P300. The age range was aged between 26 and 63 years. Ten out of the twelve presented cognitive wave latency between 512 msec and 928 msec. This finding made us conclude that repetitive minor head injuries (mHI) that they inevitably had experienced during their carrier has led to cognitive problems in older age.

Arbitrary Decision

This study investigated the hypothesis that neural markers associated with arbitrary decision-making are present in higher order, deliberate decisions. Furthermore, the study aimed to investigate the effect of higher order decision content on neurophysiological markers such as the readiness potential and the P300 potential. An experiment was designed to measure, evaluate, and compare these electroencephalographic potentials under both arbitrary and deliberate choice conditions. Participants were presented with legal cases and had to convict and acquit criminal offenders. Distinct readiness potentials and P300 potentials were observed for both arbitrary and deliberate decisions across all participants. These findings support the hypothesis that the readiness potential and the P300 potential are present in the neurophysiological data for higher order deliberate decisions. The study also showed initial findings of how the readiness potential may inherently relate to decision content. Increased readiness potential amplitudes were observed for participants with previous exposure to violent crime when they had to acquit or convict criminals accused of violent crimes.

ABSTRACT Objective To determine the prevalence of obstructive sleep apnea (OSA) in children with attention deficit/hyperactive disorder (ADHD) and compare amplitude and latency of the P300 potential among children with and without OSA. Method Sixty-one children with ADHD underwent oddball auditory attention tests for detection of P300 (ERPs) followed by an all-night polysomnography. The children were divided in two groups, those with and without OSA. Results Significant decreased amplitude of the P300 potential was observed in children with OSA when compared with children without OSA. Conclusion The study showed that sleep fragmentation as a result of OSA can exacerbate the attention disorder that characterizes ADHD, and highlights the importance of assessing the presence of OSA in the differential diagnosis of children with attention deficits.
