Aaron Nelson began his Learning & the Brain session by telling a tale on himself regarding memory. If you’ve ever left home on a car trip and wondered if you turned off the coffee pot or the stove or some other gadget, Nelson’s tale of forgetting his child’s blanket and returning home only to discover that he had left the keys to their other car in that car, which was parked in the driveway and running, will resonate! He went on to describe the components of memory, which consist of “multiple memory systems” as explained by Larry Squire and his memory schema. Scroll to the third page and notice that the diagram, which references long term memory, shows memory as residing in multiple areas of the brain.
The bulk of Nelson’s talk focused on how the brain and memory change with age. Did you know that “memory starts to decline between 25 and 30 years of age in normal situations.” He explained a bit about what scientists think happens in the brain in terms of aging and memory, further explained the concept of “cognitive reserve”, and then discussed ways to optimize memory. No doubt one reason his talk was well attended is that every last attendee had an aging brain, and a number most likely also have parents who are well ahead in the aging arena!
I took a lot of notes and was persuaded by the practical nature of Aaron’s talk to then purchase his book, The Harvard Medical School Guide to Achieving Optimal Memory.
Of particular interest was Aaron’s description of Yakov Stern and his study of cognitive reserve. SharpBrains has an informative interview with Dr Stern entitled Build Your Cognitive Reserve. I referenced cognitive reserve, or the brain-reserve hypothesis in my prior post on Ken Kosik’s talk.
As with many of the books I read, an entry or two about Aaron Nelson’s book will eventually wind up posted here. Meanwhile, I leave you with this teaser from his book:
