Reproducible paired sources from concurrent EEG-fMRI data using BICAR.
We introduce BICAR, an algorithm for obtaining robust, reproducible pairs of temporal and spatial components at the individual subject level from concurrent electroencephalographic and functional magnetic resonance imaging data. BICAR assigns a task-independent measure of component quality, reproducibility, to each paired source. Under BICAR a reproducibility cutoff is derived that can be used ...
متن کاملNeurophysiological Mechanisms Involved in Auditory Perceptual Organization
In our complex acoustic environment, we are confronted with a mixture of sounds produced by several simultaneous sources. However, we rarely perceive these sounds as incomprehensible noise. Our brain uses perceptual organization processes to independently follow the emission of each sound source over time. If the acoustic properties exploited in these processes are well-established, the neuroph...
متن کاملFusing Concurrent EEG and fMRI Intrinsic Networks
Different imaging modalities are sensitive to different aspects of brain activity, and integrating information from multiple modalities can provide an improved picture of brain dynamics. Electroencephalography (EEG) and functional Magnetic Resonance Imaging (fMRI) are often integrated since they make up for each other’s limitations. FMRI can reveal localized intrinsic networks whose BOLD signal...
متن کاملfMRI and concurrent EEG in patients with focal epilepsy: Processing of EEG signals for fMRI analysis
Introduction Two ways of performing fMRI with concurrent EEG are possible: fMRI sequence triggered manually after identification of inter-ictal spikes [1] or continuous and simultaneous fMRI and EEG acquisition. First method suffers from arbitrary selection of waiting time between appearance of inter-ictal spikes and fMRI acquisition, nonuniform MR image contrast due to T1 saturation, possible ...
متن کاملfMRI neurofeedback of higher visual areas and perceptual biases
The self-regulation of brain activation via neurofeedback training offers a method to study the relationship between brain areas and perception in a more direct manner than the conventional mapping of brain responses to different types of stimuli. The current proof-of-concept study aimed to demonstrate that healthy volunteers can self-regulate activity in the parahippocampal place area (PPA) ov...
