简介：
Overview
This protocol outlines a behavioral assay, specifically the attentional set shifting task (AST), to evaluate cognitive flexibility mediated by the prefrontal cortex in mice. The procedure involves training mice to associate a food reward with specific contextual cues and subsequently altering these cues to assess their adaptability.
Key Study Components
