The human brain is undoubtedly one of the true marvels of nature. But many of the neural mechanisms that evolved to keep our ancestors alive over thousands of years are now leaving us feeling dissatisfied, anxious and depressed thanks to the rapid advances in technology and culture we now find ourselves faced with. The simple fact is, we’re living in an environment that our brains were not built to survive in. In this episode, we’re joined by Dr Paul Goldsmith, an evolutionary neuroscientist, author and visiting professor at Imperial College London, to talk about his latest book, The Evolving Brain – An Ancient Tool in a Modern World. He tells us how the pressures and goals many of us are now confronted with are vastly different from the challenges faced by our ancestors, the huge impact this is having on our mental wellbeing by excessively triggering our natural stress responses and shares some advice from neuroscience we can all use to navigate the trials of modern life more healthily.
