Topic: visual decision-making

During decision-making, sensory input is integrated with internal priors to produce appropriate action. Theoretical work has proposed a hierarchical implementation of this process in visual cortex (Rao & Ballard 1999), but it remains unclear whether and how networks of visual cortical neurons might encode priors in a predictive manner. To investigate this, we trained mice on a standardised behavioural platform for visual decision-making (The International Brain Laboratory, 2023): mice turned a wheel to indicate whether a visual grating appeared on the left or the right, with prior probabil
