How Your Nervous System Works & Changes
Andrew Huberman・55 minutes read
The Huberman Lab Podcast hosted by Andrew Huberman provides science-based tools for everyday life, focusing on the parts list of the nervous system and its impact on experiences. The nervous system governs all biological systems, communicates through electrical activity, and is influenced by factors like sleep quality and neuromodulators, shaping perception, memory, and emotions.
Insights
- The nervous system, encompassing the brain, spinal cord, and organ interactions, forms a vital communication loop that governs all biological systems and is influenced by them.
- Neurons, the building blocks of the nervous system, communicate through synapses via electrical activity, encoding perceptions, experiences, and memories as patterns of electricity, shaping our sensations, thoughts, emotions, and actions.

- The nervous system encompasses the brain, spinal cord, connections, and organ interactions.
- It forms a continuous loop of communication between the brain, spinal cord, and body.
- The nervous system governs all biological systems and is influenced by them.
- Neurons, discovered in the early 1900s, are the building blocks of the nervous system.
- Neurons communicate through synapses, where chemicals are exchanged.
- The nervous system functions through electrical activity between neurons.
- Perception and experiences are encoded as patterns of electricity in neurons.
- Memories are stored as patterns of electricity in neurons.
- The nervous system's discoveries were influenced by wartime injuries revealing brain functions.
- Brain regions control specific functions like memory, speech, and facial recognition.
- Neurons can be activated by specific stimuli, leading to unique responses.
- The brain is a map of experiences, shaped by electrical activity in neurons.
- The nervous system governs sensation, perception, feelings, thoughts, and actions.
- Sensation involves sensory receptors perceiving external stimuli.
- Perception interprets and focuses on sensations, shaping our experiences.
- Attention acts as a spotlight, directing focus on specific sensations or perceptions.
- Thoughts are like perceptions, drawing on past experiences and future anticipations.
- Actions are crucial as they create a record of our existence and shape our behaviors.
- Movement is controlled by reflexive and deliberate pathways in the nervous system.
- Deliberate actions require top-down processing and effort to control reflexive responses.
- Emotions and feelings are influenced by neuromodulators like dopamine and serotonin.
- Neuromodulators bias neuron activity, affecting emotions and behaviors.
- Adaptive plasticity allows the brain to change in response to experiences.
- Neuroplasticity is the brain's ability to rewire and change connections.
- Neuroplasticity is triggered by neuromodulators and occurs during rest and sleep.
- Sleep and deep rest are crucial for consolidating learning and shaping the nervous system.
- The autonomic nervous system regulates alertness and calmness, influencing focus and relaxation.
- Ultradian rhythms, like 90-minute cycles, govern focus and attention throughout the day.
- Understanding sleep quality, timing, and ultradian rhythms can optimize learning and neuroplasticity.
- Mastering the autonomic nervous system and ultradian rhythms can enhance focus and learning.
- The podcast will delve deeper into sleep, rest, and optimizing brain function in future episodes.
