What happens to us when something… happens? How do humans make memories, and where do they go in our brains? Does the mind work like a filing cabinet, or is it more like your computer’s hard drive? And what happens to the brain when memory starts to fail? These are some of the questions we asked of two panelists at our lunchtime discussion, Think Science: Memory.
In the audio below, Dr. Isabel Muzzio shares her research into Declarative Memories, differentiating between Episodic (events) and Semantic (facts, subjects), and how the hippocampus plays an important role in filtering and sorting memories in our brains. She also talks about the way emotion plays an important role in the formation of core memories, and recounts the story of Henry Molaison, who in 1953 was unable to form new memories after an experimental brain surgery.
In Dr. Perry's portion of the presentation, you'll learn more about the physical changes that happen in the brain when diseases like Alzheimer's strike, the myths and facts about the disease, and ways to help ward off its onset.
