Single-Trial EEG-fMRI Reveals the Generation Process of the Mismatch Negativity
2019
Frontiers in Human Neuroscience
Preserved Fulltext
In this study, we used a single-trial electro-encephalography (EEG)-functional magnetic resonance imaging (fMRI) coupling method which can analyze neural activity with both high temporal and high spatial ...
