Use of Spatial Deconvolution to Compensate for Distortion of EEG by Volume Conduction

EEG waves recorded with electrode arrays on the brain surface give spatial patterns of cortical neural activity that are smoothed by the volume conductor properties of brain tissue. If the geometry of the EEG generators is known, the smoothing process can be described quantitatively, and the spatial patterns of underlying neural activity can be restored within limits imposed by noise and instrumental imprecision.
