In a unique and surprising study, researchers designed a rodent car out of a plastic cereal container, allowing rats to drive towards a Froot Loop treat. Rats in enriched environments learned to drive faster than those in standard cages, supporting the idea that complex environments enhance neuroplasticity. The project went viral and evolved into new, improved rat-operated vehicles, similar to a rodent version of Tesla’s Cybertruck. Further research on anticipation and positive experiences showed that rats trained to wait for rewards exhibited optimistic cognitive styles. Observing tail posture in rats revealed emotional expression and enjoyment of both the journey and the rewarding destination. This study sheds light on the importance of positive experiences in shaping brain function.
