Rats Revel in Driving Tiny Cars, Surprising Scientists

Researchers at the University of Richmond have taught rats to drive tiny cars, discovering that the rodents not only learn the skill but also enjoy it, showing excitement by revving the engine. The study, led by neuroscientist Dr. Kelly Lambert, explores how positive experiences and anticipation can impact brain chemistry, suggesting that rats in enriched environments learn faster and exhibit more optimistic cognitive styles. This research highlights the potential of 'behaviorceuticals'—experiences that alter brain chemistry similarly to pharmaceuticals.
