” Decoding How Dopamine Shapes LearningTo uncover those insights, the group collaborated with engineers and neuroscientists at the Champalimaud Centre for the Unknown to develop a novel “closed loop” system that might connect specific actions by mice to real-time dopamine release. They not only increased the frequency of the target action, however likewise of similar actions and those that happened a couple of seconds before the dopamine release. Over time, this refinement became more exact, with the mice progressively focusing on the precise action that led to dopamine release.The study also analyzed how mice discover a series of actions, revealing a crucial process comparable to rewinding time to comprehend what leads to a reward. When actions activating dopamine occurred further apart, the mice found out more slowly. In essence, actions right before the benefit are rapidly understood and enhanced upon, while earlier actions are refined more slowly.

In essence, actions right before the benefit are quickly understood and enhanced upon, while earlier actions are fine-tuned more slowly.
