Description
Hania Köver and Shaowen Bao proposed that brain flexibility stores our prior expectations in PLOS ONE in 2010. Perception blends fresh sensory input with what past experience predicts. Ambiguous signals get pulled toward the expected reading. How neurons physically keep those priors was unknown. Other theorists had suggested changing response patterns that shift over time. The authors advanced cortical plasticity, lasting change in cortex connections, as the storage mechanism.
If priors live in plastic connections, learning literally rewires perception. That would explain why expectations are stable yet updatable. The idea connects a math theory of perception, Bayesian inference, to brain hardware. It suggests experiments that track connection change as priors form. Theory papers like this steer the next round of experiments.
