Finally, we note that this component bears many similarities to the classic Contingent Negative Variation (CNV) and Readiness Potential (RP) and that our results point to a potential unifying account of these signals.

Redmond O'Connell @redmondoconnell.bsky.social · 26/02/2026
This suggests that the brain uses urgency signal not only to accelerate motor planning but also to hasten cognitive deliberation
100
Redmond O'Connell @redmondoconnell.bsky.social · 26/02/2026
But the signal is not itself directly tied to motor execution. When decision reports must be withheld until cued, this signal terminates alongside neural signatures of evidence accumulation and well before the final response.

Redmond O'Connell @redmondoconnell.bsky.social · 26/02/2026
This frontocentral ERP component builds as a function of time, but not evidence strength, and adapts to varying time pressure demands in a manner that closely tracks static and dynamic bound adjustments identified both by behavioural modeling and effector-selective motor preparation signals.
