However, the challenge of free-riders, who benefit without contributing, complicates the balance between effort and resource sharing. While previous studies have examined group characteristics and voluntary participation affecting free-riding, less is known about the intrinsic decision-making processes behind the emergence of participants and free-riders. To explore these dynamics, we conducted a 'risk-taking food retrieval' experiment with mice. Mice cohabitated with a spider robot in an arena and had to retrieve shared food placed on the robot. Using CBRAIN, we tracked neural activity in the mPFC, NAc, and BLA―regions associated with decision-making, reward, and fear.
