Why we act when we act: How brain, body, and environment interact
... How does the brain decide when to act, or whether to act in the first place, when decisions are not dictated by immediate external imperatives? The mechanisms that govern so-called “self-initiated” decisions-to-act remain poorly understood. The simplest, and perhaps most naïve, view of decision maki ...
