You must remember this

For many of us our memories are a diary of our lives. They are mental movies of where we've been, what we did, and who we are. However memories aren't as neat and tidy as photos in an album or videos on a flash drive. Our memories change every time we remember them and what we recall always has an account of times past imprinted in it. Out of necessity, our brain remembers as a way to predict the future, but it is never a static process.

Sometimes memories can disrupt our lives. Memories of traumatic events can lead to PTSD. Some researchers are investigating ways to eradicate those through a kind of chemical memory surgery and they are having some success in the laboratory doing so.

To dig deep into the mine of our minds and find our how we really remember we speak with neuroscientist Dr. Sheena Josselyn who studies memory systems at the Hospital for Sick Children. We also sit down with Dr. John Peever, a neurobiologist at the University of Toronto who studies sleep and explores its relationship to memory on the show. We're then enlightened about the differences between computer and human memory systems by former MIT visiting scholar, hacker and bioentrepreneur Connor Dickie. Finally, our last word comes from Carl Schoonover, the neuroscientist and authour of Portraits of the Mind who we also feature this week on the Brainiac book club.
