Why are some people driven to dangerous risks, while others shun danger? Why do some people seem to be born optimists, while others are more prone to worry and pessimism? Drawing on her own groundbreaking research and the research of many other scientists from around the world, Elaine Fox helps answer why. With a compelling mix of science and anecdotes, Rainy Brain, Sunny Brain addresses Why optimism is more difficult than pessimism How innocent stimuli can become triggers for terror The emergency brain: how our ancient neural circuits take over our thoughts and memories New techniques for counteracting fear and anxiety disorders Dangerous minds: the psychology of risk Perhaps most important, Rainy Brain, Sunny Brain shows how malleable our minds really are. There is increasing evidence that we can learn to change our brain states. It is possible for people trapped in pessimistic and negative mindsets to take their more “rainy” brain to a sunnier one with real change that’s reflected at the level of neurons within their brains.
