Why is it that we can vividly remember a particular smell from years ago, but can’t remember where we put our keys a mere few hours prior? This month, we’re joined by renowned neuroscientist and author Dr Charan Ranganath to discuss how and why we remember. Charan is a Professor of Neuroscience and Psychology, and Director of the Dynamic Memory Lab at UC Davis, and has recently released his first book ‘Why We Remember’. Charan takes us on a journey through our own minds, and a forward look at the future of memory research.  Ri Science Podcast episodes are released on the last Wednesday of every month.
