Emotions. They're a pain, aren't they? If only we were all a little less emotional and a lot more rational, we wouldn't get ourselves into half the scrapes we do. But is that a fair synopsis? Are emotions really some form of cognitive appendix that we'd be better off without? Or do they serve a deeper purpose? In 'The Emotional Brain', Dean Burnett investigates all these questions - and many more besides. Combining in-depth research with expert analysis, the end result is an account of the science underlying our emotional lives.
