How has our understanding of the mysterious tissue between our ears changed in the past 50 years? In her Totally Cerebral episodes onTransistor, neuroscientist Wendy Suzuki introduces us to scientists who have uncovered some of the deepest secrets about how our brains make us who we are.
Imagine that every time you met someone new, the moment they left the room you forgot you had ever spoken to them, and when they returned it was as if you had never seen them before. Imagine remembering your childhood, your parents, the history you learned in school, but never being able to form a new long term memory after the age of 27.
Most amnesic patients can’t learn or remember that particular things happened in at a particular time or in a particular place. In fact, patients with severe amnesia are no longer able to learn or remember anything about what has happened to them. However, Neal Cohen and Larry Squire showed that the same amnesic patients could learn and remember how to do things, like work a lock, or solve a puzzle with blocks, or swing a racquet.
Scents and tastes are powerfully evocative — one whiff of perfume or cooking aromas can transport you back to a particular moment, a particular place, a particular person. Because the things we smell reach two brain structures called the hippocampus and amygdala in just one synapse, scents can almost immediately stimulate the key brain areas for memory, emotion, and location.
A story of movement, memory, and mentors. Dr. Wendy Suzuki introduces us to Dr. Marian Diamond, whose lively classes ushered Wendy into a career in neuroscience. And Wendy shares how she came to study how exercise profoundly affects the brain, not just the body.
