Summary
Recordings from 19 epilepsy patients showed the brain manages ongoing decisions by blending multiple goal-directed strategies in real time, rather than flipping between simple either-or choices.
A joystick prey-pursuit task paired with computational modeling found the hippocampus tracks current and future task states, helping plan upcoming actions as conditions change.
The study also mapped a three-part network: the anterior cingulate cortex acts as a meta-controller shifting priorities, while the orbitofrontal cortex encodes the value of available options.
Published in Nature, the findings challenge the long-standing view of the hippocampus as mainly a memory center and broaden its role in moment-to-moment decision-making.
