Abstract In a dynamic environment, sensory systems must filter out irrelevant information to construct a stable percept. Animals who rely on smell need to identify and discriminate odors despite fluctuations in concentration, yet odor receptor activation is strongly concentration dependent.

Highlights • Auditory cortex is dispensable for discrimination of dissimilar pure tones in mice • Auditory cortex is involved in a sound discrimination requiring temporal integration • Focal cortical activations bias choices in cortex-dependent discriminations • Discrimination is faster for pure tones than for optogenetic cortical activations Summary Driving perception by direct activation of neural ensembles in cortex is a necessary step for achieving a causal understanding of the neural...
