Scientists have uncovered that the brain’s dopamine system doesn’t simply predict if a reward is coming, but also precisely when to expect it—offering fresh insights into motivation, addiction, and even artificial intelligence. This new study, led by researchers at the University of Geneva and published on June 9, 2025, fundamentally changes our understanding of how the brain’s reward circuitry times and values pleasurable experiences, opening new avenues for practical applications in health and education (ScienceDaily).
