Abstract

Prefrontal cortex (PFC) is thought to support the ability to focus on goal-relevant information by filtering out irrelevant information, a process akin to dimensionality reduction. Here, we find direct evidence of goal-directed data compression within medial PFC during learning, such that the degree of neural compression predicts an individual's ability to selectively attend to concept-specific information. These findings suggest a domaingeneral mechanism of learning through compression in mPFC.
