It may sound pedantic or philosophical to worry about definitions of “behavior,” “control,” and “understanding.” But for a field as young and diverse as neuroscience, dismissing these foundational discussions can cause a great deal of confusion, which in turn can bog down progress for years, if not decades. Unfortunately for today’s neuroscientists, we rarely talk about the assumptions that underlie our research.By these definitions, we don’t currently “understand” the brain
