Perception is uncertain. Repeated presentations of the same stimulus elicit variable perceptual impressions. To robustly guide behavior, the neural circuits that mediate perception must therefore extract both feature estimates and feature uncertainty from sensory inputs. How they do so is not well understood. We addressed this question using an approach that combines three components. First, a rich stimulus set which varies in feature value and uncertainty. Second, observation of neural population activity in a sensory circuit that represents these features. And third, a maximum likelihood dec
