Sep 29, 2025 Dr. Poppy Crum, a neuroscientist and former Chief Scientist at Dolby, dives into the fascinating world of neuroplasticity and how sensory experiences retrain our brains. She shares insights on using smartphones and video games as tools to enhance learning and decision-making. Crum introduces the concept of 'digital twins'—dynamic representations of our environments and bodies that optimize health. With a focus on AI, she discusses its role in learning, revealing weaknesses, and improving cognitive skills without diminishing our ability to engage deeply.

Episode notes
Brain Maps Rewire With Experience
- Our brain allocates neural resources (maps) to tasks we practice, changing sensitivity and specificity.
- Neuroplasticity sculpts these maps based on active engagement and environmental statistics.
Environment Programs Sensory Thresholds
- Everyday technologies reshape our sensory thresholds and priors, such as hearing sensitivity tied to city noise.
- These environmental statistics bias perception and neural processing across the lifespan.
Absolute Pitch Shapes Everyday Perception
- Poppy describes noticing annoying hotel noises because her absolute pitch makes auditory cues salient.
- Her perfect/absolute pitch causes immediate sensitivity to pitch and room acoustics.
