Rapid emergence of latent knowledge in the sensory cortex drives learning.

ABSTRACT: Rapid learning confers significant advantages to animals in ecological environments. Despite the need for speed, animals appear to only slowly learn to associate rewarded actions with predictive cues^1-4. This slow learning is thought to be supported by a gradual expansion of predictive cue representation in the sensory cortex^2,5. However, evidence is growing that animals learn more rapidly than classical performance measures suggest^6-8, challenging the prevailing model of sensory cortical plasticity. Here, we investigated the relationship between learning and sensory cortical representations. We trained mice on an auditory go/no-go task that dissociated the rapid acquisition of task contingencies (learning) from its slower expression (performance)⁷
