In this podcast episode, we dive into the fascinating functions of the nervous system, including sensation, perception, emotions, thoughts, and actions, and how they all connect. A key focus is on neuroplasticity, the brain's remarkable ability to adapt, which is shaped by neuromodulators like dopamine and serotonin. Neuroplasticity unfolds in two stages: first, through concentrated effort and attention during learning, and then through consolidation during sleep and deep rest. To enhance learning and optimize nervous system function, it's important to understand and leverage 90-minute ultradian rhythms in both sleep and wakefulness. Additionally, mastering the balance of the autonomic nervous system—navigating between alertness and calmness—is crucial for regulating these rhythms and boosting neuroplasticity.
