This is a method for studying subcortical structures, or parts of cortex in the medial surface of the cerebral hemispheres that are far away from the sensors. Based on the raw data, it removes the part of the signal subspace that comes from cortical sources while sparing subcortical data. Could be useful as a function on a raw object in the preprocessing stage.
