The study of brain anatomical and functional connectivity is one of the major issues of neuroscience, aiming at better understanding the organization and functioning of the brain, whether in healthy or diseased individuals. Anatomical connectivity is generally studied with diffusion MRI sequences.
Functional connectivity is usually investigated via functional MRI sequences (fMRI).
