Single-trial analysis of oddball event-related potentials in simultaneous EEG-fMRI.
There has recently been a growing interest in the use of simultaneous electroencephalography (EEG) and functional MRI (fMRI) for evoked activity in cognitive paradigms, thereby obtaining functional datasets with both high spatial and temporal resolution. The simultaneous recording permits obtaining event-related potentials (ERPs) and MR images in the same environment, conditions of stimulation,...
متن کاملAveraging techniques for single-trial analysis of oddball event-related potentials
More and more effort is done in BCI research to improve its usability for patients, with respect to its communication speed and transmission accuracy. In this contribution, we experiment with BCI speller based on P300 evoked potential. More precisely, the typical form of event-related potential (ERP) inspires us to devise classification methods based on the similarity/dissimilarity in the time ...
متن کاملAuditory event-related potentials and α oscillations in the psychosis prodrome: neuronal generator patterns during a novelty oddball task.
Prior research suggests that event-related potentials (ERP) obtained during active and passive auditory paradigms, which have demonstrated abnormal neurocognitive function in schizophrenia, may provide helpful tools in predicting transition to psychosis. In addition to ERP measures, reduced modulations of EEG alpha, reflecting top-down control required to inhibit irrelevant information, have re...
متن کاملAuditory event-related responses to diphthongs in different attention conditions.
The modulation of auditory event-related potentials (ERP) by attention generally results in larger amplitudes when stimuli are attended. We measured the P1-N1-P2 acoustic change complex elicited with synthetic overt (second formant, F2Δ=1000Hz) and subtle (F2Δ=100Hz) diphthongs, while subjects (i) attended to the auditory stimuli, (ii) ignored the auditory stimuli and watched a film, and (iii) ...
متن کاملChanges in Event-Related Desynchronization and Synchronization during the Auditory Oddball Task in Schizophrenia Patients
OBJECTIVE We studied differences in the spatiotemporal dynamics of cortical oscillation across brain regions of patients with schizophrenia and normal subjects during the auditory oddball task using magnetoencephalography (MEG) and electroencephalography (EEG). METHODS Ten right-handed male schizophrenia patients were studied. We used a newly developed adaptive spatial filtering algorithm opt...
