Circuit basis of simple auditory judgements

We are using auditory discrimination tasks in rodents, together with large-scale cortical population recordings and theory, in order to study the circuit basis of simple sensory judgements. We focus on several aspects of this problem, such as the population structure of trial-to-trial variability in auditory cortex and its relationship to behavioral accuracy, the way in which external sensory evidence is combined with prior expectations in local auditory cortical circuits, the role of different, genetically-identified cell types, in shaping the overall dynamics of spontaneous activity and evoked auditory responses, and the functional role of such dynamical, time-varying activity patterns in the context of auditory categorizations.
