Enhance Your Learning Speed & Health Using Neuroscience Based Protocols | Dr. Poppy Crum

About this video

Neuroscientist Dr. Poppy Crum argues that human brains are much more plastic than most people realize, in conversation with Huberman. Dr. Crum discusses how technology might accelerate neuroplasticity and learning, including wearables and emerging hearable technologies that Huberman describes as able to infer states from voice and adjust home or work environments to support focus, relaxation, and connection. Dr. Crum shares discovering perfect pitch at a young age and how it shaped her worldview. She also describes using dynamically cooling and heating sleep technology, saying heating toward the end of the night increased her REM sleep while cooling at the beginning increased deep sleep. Huberman raises a gap in the field: sleep states are well named, while distinct awake states for different kinds of work remain poorly defined, limiting what technology can optimize.

Key takeaways

• Dr. Crum argues brains are much more plastic than people typically realize in daily life.
• Dr. Crum describes sensor and AI systems that could adjust environments to support focus and relaxation.
• Dr. Crum says temperature changes across the night affected her deep sleep and REM sleep differently.
• Huberman argues neuroscience has poorly defined distinct states of wakefulness compared with sleep states.
• Dr. Crum provides a step-by-step protocol for building a custom AI tool to improve at a chosen skill.
