Brain connectivity: An opening window into addiction

摘要

Almost twenty years ago, brain connectivity based on brain-imaging data (or alternatively, mapping of the macro-connectome) was introduced to the field (1). Since then, we have learned a lot about methodology, imaging approaches, and brain health and disease using approaches based on connectivity. Approaches range from univariate correlation between targeted regions of interest (1) to data-driven multivariate approaches like group independent component analysis (2). In this commentary, I touch on three topics: (1.) the prevalence of studies of connectivity in the area of substance use disorders, (2.) the information brain connectivity can provide us, and, (3.) some future directions in brain connectivity.
