Topic: memory-based behavioural decisions

To guide memory-based behavioural decisions, the hippocampus needs to discriminate between distinct sensory environments. Before reaching the hippocampus, sensory information is initially processed in sensory cortices. We hypothesised that primary sensory cortices provide a faithful representation of the sensory environment to distributed brain regions, whereas the hippocampus produces a cognitive map weighted according to the behavioural relevance of sensory inputs. To test this hypothesis, we aimed to determine how complex sensory stimuli differentially depend on the behavioural context in t
