Estimation of Brain Electrical Sources Using Multilevel Source Space Model

This paper describes a proposal for a new source space model called the multilevel source space model for the efficient and precise estimation of brain electrical activities. Unlike conventional source models, the proposed one generates both high- and low-resolution brain models which represent gray matter of a human cerebral cortex. The model can then be used to estimate brain electrical sources in a multiresolutive way. The usefulness of the proposed model has been verified using realistic simulations with real brain noise and anatomy
