This paper investigates how the auditory cortex drives rapid learning and slower performance improvements in mice during an auditory go/no-go task, revealing two distinct higher-order signals involved in these processes.

This study shows that cholinergic basal forebrain axons send non-habituating, stimulus-specific sensory signals to the auditory cortex, independent of local tonotopy and modulated by slow cholinergic activity.

The paper shows that knowledge acquisition and expression can be dissociated by using probe trials without reinforcement, revealing that performance variability stems from testing context rather than inherent ability.
