RL Debates 4: Adam “I literally measured value in the brain” Lowet

In our 4th RL Debates presentation, Adam presented broad topics on RL and the brain, including his distributional RL paper.

• Paper: An opponent striatal circuit for distributional reinforcement learning
• Slides: Drive link
• Presenter: Adam Lowet

Adam’s talk covered a lot of ground. He presented his recent work on distributional RL, which provides causal evidence that the brain computes a full probability distribution of value rather than a single number. He showed evidence for an opponent circuit in the striatum that could perform this function. He then placed this finding within a broader discussion of the open challenges in linking RL theory to complex, real-world brain function and behavior.
