Figure 3. Deliberative action-selection.

Figure 3

(A) Anatomy of the deliberative action-selection system in rat (left) and human (right). (B) Deliberation can be conceptualized as a serial search through future possibilities, including expectations of potential situations (E[S]) and valuations performed online of those expecations (E[V]). (C) Computationally, this requires a forward model to search over. (D) In practice, this computation takes time and produces pausing and VTE behavior. As shown in the video (Supplemental Video S1), deliberative behavior is visible as pausing and head swings. Diagrams correspond to laps 2 and 4 shown in the video.
