Abstract

âº MEG can track the afferent information flow along thalamo-cortical fibers. âº Deep thalamic sources can be localized by MEG with an accuracy of ~2 cm.âº Thalamo-cortical volleys present an inhomogeneous conductivity velocity. âº Functional fiber tracking can identify the brain reorganization in lesion patients.
