Behavioral and Brain Sciences (​BBS) is an internationally renowned journal with an innovative format known as Open Peer Commentary. Particularly significant and controversial pieces of work are published from researchers in any area of psychology, neuroscience, behavioral biology or cognitive science, together with 20-40 commentaries on each article from specialists within and across these disciplines, plus the author's response to them. The result is a fascinating and unique forum for the communication, criticism, stimulation, and particularly the unification of research in behavioral and brain sciences from molecular neurobiology to artificial intelligence and the philosophy of the mind.
