Discovery of differences in the brains of rats classified as workers vs. slackers

Neurologists have uncovered a network of regions in the brain that are involved in determining the choice of being a ‘hard-worker’ or a ‘slacker.’ Understanding how the brain makes such decisions is one of the most fundamental questions in neuroscience and psychology, and sophisticated animal behavioral testing, coupled with advance brain imaging and stimulation techniques are shedding light on this important process.
