Fabrizio Musacchio🍬🐁 🧠 New paper by Gong et al: Larger rewards can make #mice learn much faster than standard low-reward protocols suggest.
Across navigation, motor-skill & #DecisionMaking tasks, reward magnitude improved #learning efficiency by increasing learning rate, sustaining task engagement & helping carry improvements across sessions. Larger rewards also produced stronger, longer striatal #dopamine responses, & #optogenetic DA boosting reproduced part of the effect.
