What does the lowly laboratory rat have to teach about being human? To behavioural neuroscientist Kelly Lambert, a whole lot. Her 25-year career conducting experiments that involve rats has led her to a somewhat surprising conclusion: through their adaptive life strategies, these unassuming and sometimes even reviled little rodents demonstrate the central secrets of how humans can lead successful lives. Generous with fascinating findings and quirky observations and informed by the passion of a researcher at the top of her game, Lambert sheds light on rats - and humans.
