Abstract Synopsis

  • The paper discusses how dopamine in the brain is thought to encode reward predictions, traditionally seen as a single number representing the expected reward, but the authors propose that it might actually represent a whole distribution of possible future rewards.
  • Inspired by recent AI research, the authors suggest that the brain might process multiple potential outcomes at once, rather than just the average, which could explain more complex reward learning.
  • Their experiments with mice support this idea, showing neural activity consistent with the brain representing a distribution of future rewards, giving us a new way to understand how dopamine helps with learning and decision-making.]
