In what seems like a debatable outcome of interest, our brain exemplifies one of its capabilites - plasticity. In multiple studies researchers compared the grey matter (neuronal cell bodies) as well as white matter (composed of dendritic processes of neuronal cell bodies, commonly referred to as nerves) of people actively training juggling and control groups who don’t. With magnet resonance imaging (MRI)[ voxel based morphometry, VBM for black matter and Diffusion Tension Imaging, DTI) the participants’ brains were assessed and screened for changes.
