简介：
Overview
This protocol outlines a method for whisker-signaled eyeblink conditioning in head-fixed mice, allowing for precise whisker stimulation while enabling ambulation on a cylindrical treadmill. The approach facilitates the investigation of the neurobiological basis of learning and memory through associative learning paradigms.
