The mammalian auditory system is remarkably adaptable, allowing animals to flexibly respond to sensory information in dynamic environments. Flexible behaviors, such as perceptual learning, involve the engagement of various neural circuits including top-down regions such as frontal areas. However, how multiple brain areas communicate to support learning is unclear. Here, we investigate how frontal and sensory cortical areas interact to enable flexible behavior. We used high-density silicon probes to record single-unit responses simultaneously from auditory cortex (AC), and a downstream region i
