An approach to estimation of EEG of deep regions and visualization of brain activity, based on source derivation method

摘要

Generally, it is difficult to know three-dimensional brain activity from the data of EEG recording. But making use of Source Derivation(SD) method, it is possible to estimate the EEG from deep regions of brain. Therefore it may be possible to know a brain activity of upper hemisphere. In this paper, we evaluate SD method for EEG recording, and we propose the system for visualization of a three-dimensional brain activity by taking potential data of shallow and deep regions. we also evaluate this system.
