On the way today from the campsite to the Tim Hortons (my PEI office) I listened to an excellent discussion of memory on the CBC Radio program Think About It. It's worth a listen. It nicely responds to the (very incorrect) 'stored picture' and 'brain as disk drive' concepts of memory, describing and explaining how memories are created as activations of neural systems, the impact of context (via emptional and other physical states) on memory, and the role of sleep. Host Roberta Walker talks with neuroscientist Sheena Josselyn who studies memory systems at the Hospital for Sick Children, John Peever, a neurobiologist at the University of Toronto, former MIT visiting scholar, hacker and bioentrepreneur Connor Dickie, and  Carl Schoonover, neuroscientist and authour of Portraits of the Mind
