Your brain physically reroutes its communication lines based on how confused or certain you feel.

Frontoparietal Hub Connectivity Integrates Information from Multiple Sources

The Takeaway
Brain hubs are not fixed 'wires' but dynamic systems that rewire themselves based on uncertainty (entropy). This allows the brain to optimize how it integrates information specifically for the level of confusion in a given task.
From the abstract
Frontoparietal connector hubs are thought to support information integration across the brain, but this role has largely been inferred from static connectivity, leaving unclear how computational processes shape inter-regional connectivity during behavior. Here, we address this question using a model-based functional connectivity approach in fMRI data from 38 human participants (male and female). Participants performed a task requiring the integration of sensory evidence with an internally mainta
