Objective. To quantify latency, amplitude and topographical differences in event-related potential (ERP) components between multiple sclerosis (MS) patients and controls and to compare ERP findings with results from the paced auditory serial addition test (PASAT). Methods. Fifty-four subjects (17 relapsing remitting (RRMS) patients, 16 secondary progressive (SPMS) patients, and 21 controls) com...

In a double blind, crossover study of the response of autistic subjects to fenfluramine, event-related potentials (ERPs) were recorded from 7 subjects on an attention-demanding auditory choice reaction time task (ACRT). ACRT, IQ and biochemical measures were taken after 5 months placebo and 5 months fenfluramine treatment. After fenfluramine treatment blood serotonin levels fell, urinary catech...

Abstract Introduction The mechanism underlying the development of excessive daytime sleepiness (EDS) in obstructive sleep apnea (OSA) remains unclear. Thus, we characterised association between architecture and EDS individuals with without OSA. Methods 1876 suspected OSA patients reporting underwent in-lab polysomnography next-day multiple latency test (MSLT). We investigated characteristics (a...

Nowadays, the mechanisms involved in the genesis of event-related potentials (ERPs) are a matter of debate among neuroscientists. Specifically, the debate lies in whether ERPs arise due to the contribution of a fixed-polarity and fixed-latency superimposed neuronal activity to background electroencephalographic oscillations (evoked model) and/or due to a partial phase synchronization of the ong...

Cues to pitch include spectral cues that arise from tonotopic organization and temporal cues that arise from firing patterns of auditory neurons. fMRI studies suggest a common pitch center is located just beyond primary auditory cortex along the lateral aspect of Heschl's gyrus, but little work has examined the stages of processing for the integration of pitch cues. Using electroencephalography...

Twenty-six native English Speakers identified auditory (A), visual (V), and congruent and incongruent auditory-visual (AV) syllables while undergoing electroencephalography (EEG) in three experiments. In Experiment 1, unimodal (A, V) and bimodal (AV) stimuli were presented in separate blocks. In Experiment 2, the same stimuli were pseudo-randomized in the same blocks, providing a replication of...
