MEG data Overlaid on a 3-D Brain

MEG overlay animation

The animation above demonstrates MEG results overlaid on the corresponding brain structures and how the software can visualize the 3-dimensional reconstruction of the brain from numerous vantage points. The convolutions in the cerebral cortex create a complex 3-D geometry that is used to constrain MEG source localization analyses. Shown here is the interface between grey matter (brain cells) and white matter (connecting fibres between brain cells), which make the brain to look more concave in these reconstructions. The majority of brain activity measured by MEG takes place in the cortex (the outer layer of the brain).

The 3-dimensional brain structures are obtained from anatomical Magnetic Resonance Imaging (MRI). The anatomical MRI is obtained at UNF (Unité de neuroimagerie fonctionelle) de l'Université de Montréal).

Note to those with a slow Internet connection: each of the 4 frames will take a few seconds to load but once this is done, the animation will repeat at the intended rate.
