Gray Matter: Gray matter refers to the regions of the brain that primarily consist of cell bodies and synapses. Changes in physical structure can involve alterations in gray matter volume.
White Matter: White matter refers to the parts of the brain that primarily consist of myelinated axons. Changes in physical structure can also involve modifications in white matter connectivity.
