Reduction of motion-related artifacts in resting state fMRI using aCompCor.

abstract：:It is crucial to understand what brain signals can be decoded from single trials with different recording techniques for the development of Brain-Machine Interfaces. A specific challenge for non-invasive recording methods are activations confined to small spatial areas on the cortex such as the finger representation o...
