Lynn and John are joined by Matthew Cobb on Cool Science Radio. Cobb has written The Idea of the Brain, the Past and Future of Neuroscience. For thousands of years, philosophers and scientists have tried to understand what the brain, with its 86 billion neurons, connected in infinite ways, does. Yet, despite the astonishing discoveries of science, we still have only the vaguest idea of how the brain works. We will speak with Matthew about the history of brain science but more importantly what current research on the human brains is telling us.
