In this episode, Gianluca and Jared discuss the neurobiology of predictive processing, the role of dopamine in reward signalling, satisfaction, and human desire. They also touch on the relation of reward to reinforcement learning and artificial intelligence.
The podcast then shifts to discuss the clinical manifestations of the predictive brain, including the computational psychiatry of depression, autism-spectrum-disorder, and schizophrenia, and how top-down prediction, and precision-weighted prediction error explain central aspects of these conditions.

This week’s episode of Bit of a Tangent is a continuation of our 3 part series on Predictive Processing - a fascinating neuroscientific account of the way our brains come to understand the world. If you haven’t already listened to part 1 (episode 028), check that out first!
In this episode Gianluca and Jared discuss the importance of sensory precision, the circular causality of prediction and action, how action comes about in a counterintuitive way from high confidence predictions, the way in which prior expectations can bias sensory sampling, and how this could lead to self-fulfilling spirals that would make your life either much worse or much better!

It's here. It's finally here! The first in a series of three episodes diving into the predictive processing theory of brain function! Jared and Gianluca discuss top-down versus bottom-up perception, Bayesian Brain hypotheses, the logic of caring only about prediction error, and the phenomenology of visual illusions!
