How to Learn Skills Faster | Huberman Lab Podcast #20

Neural Mechanisms

Understanding the neural mechanisms involved in skill learning is crucial for effective acquisition. Andrew Huberman explains that lower motor neurons in the spinal cord are responsible for muscle activation, while upper motor neurons communicate with central pattern generators (CPGs) to control rhythmic movements 1. These CPGs, located in the spinal cord, manage repetitive actions like walking or cycling, even in the absence of higher brain functions 2. Huberman emphasizes the importance of sensory perception, movement, and proprioception in skill learning, noting that proprioception allows us to sense limb positioning subconsciously 3.

CPGs are amazing, and they control a lot of our already learned behavior. When you're really good at something, CPGs are controlling a lot of that behavior.

These insights underscore the complexity and efficiency of our nervous system in mastering skills.

   

Open vs. Closed-Loop

Skill acquisition can be categorized into open-loop and closed-loop processes, each with distinct characteristics. Andrew Huberman describes open-loop skills as those where feedback is received after the action, such as throwing darts, while closed-loop skills involve continuous feedback, like adjusting stride during a run 4. Recognizing whether a skill is open or closed-loop is essential for optimizing learning strategies. Huberman also highlights the role of post-training mental rehearsal, where the brain replays sequences to consolidate motor skills more rapidly 5.

You should always know before you try and learn a skill, whether or not it's open loop or closed loop.

This understanding aids in tailoring practice sessions to enhance skill development effectively.
