Performance-gated deliberation: A context-adapted strategy in which urgency is opportunity cost
Fig 6
Comparing neural urgency and collapsing decision boundaries.
(A) Top: Rising belief (blue) meets collapsing decision boundary (black dashed) in belief space. Middle: Falling commitment cost (blue) meets rising deliberation cost (black-dashed) in cost space. Bottom: Belief/commitment cost is encoded (blue) into a low-dimensional neural manifold, with the addition of an urgency signal (orange) (c.f. Figure 8 in [8]). The decision (red circle) is taken when the sum passes a fixed threshold (black-dashed). (B) Deliberation cost maps onto the urgency signal extracted from zero-evidence conditioned cell-averaged firing rate in PMd (200ms time steps).
