The effects of chronic exposure to xylene on cognitive ability were studied in a group of 35 medical workers occupationally exposed to low-level concentrations of xylene for at least five years by using event-related potentials (ERPs), and compared with a control group of 21 subjects. The exposure to xylene was confirmed through determination of m-methylhippuric acid, a reliable biological indi...

Haishan Liu, Gwen Frishkoff, Robert Frank & Dejing Dou Department of Computer and Information Science, University of Oregon, USA NeuroInformatics Center, University of Oregon, USA Language Imaging Laboratory, Medical College of Wisconsin, USA Introduction: We describe an ontology-based method for representation and integration of neuroscience data, with an application to event-related brain pot...

Event-Related Potentials have been found to be related to subjective experience of experimental pain. But how are they related to the subjective experience of clinical pain? The current study investigated the predictive value of the pain ERP for the subjective experience of clinical pain. Event-Related Potentials in response to experimental pain were measured in 75 chronic low back pain suffere...

In this paper we present a simple and straightforward approach to the problem of single-trial classification of event-related potentials (ERP) in EEG. We exploit the well-known fact that event-related drifts in EEG potentials can well be observed if averaged over a sufficiently large number of trials. We propose to use the average signal and its variance as a generative model for each event cla...

Emotions are necessary to understand the behavior of an individual. andrealistic decision-making. Since number of techniques can be used for emotion recognition such as voice, facial expression of an individual but these channels can be faked. In this paper, main emphasis is given toward the acquisition of EEG signal emotion evoking picturesprovided by International Affective Picture S decompos...

The feasibility of recording event-related potentials (ERP) during functional MRI (fMRI) scanning was studied. Using an alternating checkerboard stimulus in a blocked presentation, visually evoked potentials were obtained with their expected configuration and latencies. A clustered echoplanar imaging protocol was applied to observe the hemodynamic response due to the visual stimulus interleaved...

There has been plenty of research concerning the representation of voluntary action in the human brain. However, the question of how we represent the voluntary omission of an action has been largely neglected. Therefore this study aimed at investigating the representation of intentionally not doing something by means of event-related potentials (ERPs). Free-choice nonactions elicit similar evok...

incapability in face perception and recognition is one of the main issues in autism spectrum disorders (asd). event related potential (erp) studies have revealed controversial insights on autistic brain responses to faces and objects. the current investigation examined the erp components of young children with asd compared to a typically developing (td) group when looking at the upright and inv...

background and aim: auditory p300 is an event-related potential. cognitive factors like attention are involved in the generation of p300. it seems that normative variation of p300 is necessary for clinical purposes. thus, the current study was designed to establish preliminary normative variation of p300 amplitude and latency at fz and cz sites in adults. methods: this cross-sectional study was...

Background Electroencephalogram (EEG)-based neurofeedback (NF) allows reward of desired brain activity in milliseconds. Compared to frequency power-based approach during resting state EEG, event-related potentials (ERPs) based NF a task is technically challenging because the cost computation over time window. We have previously established that left-frontal memory-related discriminate normal co...
