Orbitofrontal see‑saw decisions

Intracranial recordings in human orbitofrontal cortex show risk–reward choices emerging from two localized patches that antagonize one another like a see‑saw, rather than from a single accumulating signal. These dynamics can predict a person's choice roughly half a second before they act in an immersive risk/reward task. — If risk decisions are encoded as opposing local signals in OFC, that affects debates about neurolaw (predicting and attributing choice), behavioral interventions (targeting specific computations for nudges), and how AI should model human decision heuristics.
