The Westend Lectures on Brain and Cognition with Uta Noppeney
How the brain forms a representation of the world across the senses

Our senses are constantly bombarded with a myriad of diverse signals. Transforming this sensory cacophony into a coherent percept of our environment relies on solving two computational challenges: First, we need to solve the causal inference problem - deciding whether signals come from a common cause and thus should be integrated, or come from different sources and be treated independently. Second, when there is a common cause, we should integrate signals across the senses weighted in proportion to their sensory reliabilities. I will present our recent research at the behavioural, computational and neural systems level that investigates how the brain addresses these two computational challenges in multisensory perception.
