How does the brain perceive? Does it use the information coming in through the various senses, such as our eyes and ears, and build up a perception of the world outside from the bottom up? Or is it doing something quite different? New thinking in neuroscience suggests that the brain builds models of whats out there and uses these models to interpret the incoming sensory dataan idea that goes back to Plato, Kant and most recently to German physicist and physician Hermann von Helmholtz. Perceptionof any sort, including perception of our bodyis inherently an inference on the causes of the information impinging on our senses. According to this predictive processing hypothesis, the brain is always making informed predictions, and its these predictions that we perceive at all times.
A panel of scientists and writers will discuss the predictive brain from multiple perspectives. Celeste Kidd, professor of psychology, will discuss the predictive brain in the context of a developing childs brain. Computer scientist Christos Papadimitriou will share his thoughts on the intersection of these ideas with computer science. Neuroscientist Bruno Olshausen will shed light on visual perception and the predictive brain. Michael Pollan, author of How To Change Your Mind, will speak about his experiences with psychedelics and how psychedelic hallucinations tie in with current ideas of perception as prediction. Anil Ananthaswamy, author of The Man Who Wasnt There, will moderate the discussion and share ideas about how neuropsychological conditions such as schizophrenia are being understood from the point of view of the predictive brain.
