A team of researchers at the University of Richmond have taught rats to drive mini-cars - and not only are the rodents good at it, they enjoy it too. [...]
The study found that the rats actually felt more relaxed after driving, with heightened levels of dehydroepiandrosterone (DHEA), the hormone that counteracts stress. [...]
That result was reinforced when the rats were given ‘passengers’, with researchers noting that only the animals actually driving the car saw a decrease in stress.
