Topic: latent decision variable

Signals related to self generated movements are broadcast to non-motor brain regions, and can be detected across wide regions of the forebrain in mice. Indeed, it has been observed that, even during the performance of a task, incidental movements, or ‘fidgets’, account for much more variance in neural activity than task-related movements and task-related variables. Some bodily movements or expressions, such as those of the face, reflect biologically significant expressions of internal state, that is, emotions, which have important relationships with ongoing cognitive processes such as decision
