6 Key Concepts
Neuroplasticity
The nervous system's incredible ability to change itself, even through conscious decision, allowing for directed changes in brain function and behavior. It is a capacity for change, not an end goal in itself, and should be directed toward specific desired outcomes.
Short-Term Plasticity
Any kind of temporary shift in brain state or behavior that one wants to achieve in the moment or day, but not necessarily hold onto forever. An example is using a tool to become more alert for a specific early morning task, with the expectation of discarding that need later.
Long-Term Plasticity
Changes that result in the brain reflexively working differently, making learned skills or behaviors automatic without conscious thought. This is often the ultimate goal when people talk about optimizing the brain, such as learning a new language or skill to the point of automaticity.
Go/No-Go Circuit
A neural circuit involving the forebrain and basal ganglia that facilitates or suppresses action. The 'Go' pathway, triggered by dopamine binding to D1 receptors, promotes action, while the 'No-Go' pathway, involving dopamine binding to D2 receptors, suppresses action. This balance is crucial for focused work and learning.
Creativity (Two-Part Phenomenon)
Creativity is a state of mind that involves taking existing elements and rearranging them in novel ways. It has two parts: a 'creative discovery mode' for playful exploration and novel associations, and a 'linear implementation mode' for robustly and concretely developing the conceived idea.
Pre-Sleep Alertness Blip
A natural, brief peak in alertness and wakefulness that occurs about an hour before bedtime, driven by the circadian clock's output. This phenomenon, often mistaken for insomnia or anxiety, is believed to have historically helped humans prepare for a night's sleep.
10 Questions Answered
Plasticity itself is not the goal; it's merely the capacity for the nervous system to change. The true goal is to figure out how to access plasticity and then direct it toward specific desired changes or goals.
The trigger for plasticity and learning occurs during states of high focus and alertness, but the actual rewiring and reconfiguration of brain connections happen during non-sleep deep rest (NSDR) and deep sleep.
It depends on your level of autonomic arousal. If you are very alert, silence is best for focused learning. If you are tired or low arousal, some background noise can help elevate alertness and focus.
Exercising early in the day not only helps with waking up but also triggers the release of neuromodulators like epinephrine, creating a neurochemical context that heightens arousal and mental acuity for the late morning and afternoon.
Fasted states and low-carbohydrate intake generally increase alertness, while ingesting large amounts of food, especially carbohydrate-rich meals, tends to promote calmness and sleepiness by diverting blood to digestion and stimulating tryptophan release.
Creativity involves a 'creative discovery mode' for exploring novel configurations of existing elements, often in a relaxed or playful state, and a 'linear implementation mode' for robustly and concretely developing the conceived idea.
Yes, it is normal. The circadian clock signals a peak in alertness and wakefulness about an hour before bedtime, a natural blip that typically passes after 45-60 minutes and is believed to have historically helped humans prepare for sleep.
Visualization can be effective if one can maintain a very linear, deliberate, and focused approach during the visualization. However, for many, the mind drifts too easily, limiting its utility for performance improvement.
Waking up periodically during sleep is normal and often indicates that one's natural bedtime, aligning with sunset, was much earlier than when they actually went to sleep. Modern artificial light use often pushes bedtimes later, causing melatonin to subside earlier in the night.
It's advisable not to trust anything you think about when waking up in the middle of the night, as that period is generally not conducive to creative thinking or linear implementation. Instead, consider using non-sleep deep rest protocols to fall back asleep.
29 Actionable Insights
1. Plasticity Goal Setting
Understand that plasticity is not the goal, but a capacity for the nervous system to change. Define specific end goals (e.g., learning a language, improving focus, reducing stress) to direct this plasticity effectively.
2. Leverage Plasticity for Change
If you are happy or unhappy with an aspect of your life and wish to shift it positively, leverage neuroplasticity mechanisms, which are available at any stage throughout the lifespan.
3. Trigger, Consolidate Plasticity
Trigger learning and brain changes during states of high focus and alertness. The actual rewiring and reconfiguration of brain connections then occur during non-sleep deep rest (NSDR) and deep sleep.
4. Observe Your Internal System
Become an observer of your own system to understand what works for you, recognizing your position on the autonomic arousal scale (alert vs. calm) and matching tools and activities to your specific goals.
5. Slot In Brain Optimization
Integrate brain optimization segments of about 90 minutes (one or two, or more, per day) into your schedule, anchoring them to your natural biological rhythms like peak alertness or post-NSDR calm.
6. Morning Light Exposure
Get sunlight in your eyes in the first 30 minutes of the day (or use a bright light if natural light is unavailable) to help wake up, prime connections between melanopsin cells and the circadian clock, and reinforce cortisol release for increased alertness.
7. Delay Morning Caffeine
Delay caffeine intake for the first two hours after waking to allow natural cortisol release to occur and keep adenosine receptors unoccupied, preventing a mid-morning crash and enhancing caffeine’s later effect on alertness.
8. Hydrate Immediately Upon Waking
Drink water first thing in the morning to prevent dehydration, which can cause headaches and increase vulnerability to migraines.
9. Exercise Early for Energy
Exercise early in the day (within an hour, no later than three hours after waking) to bias towards earlier waking, trigger the release of neuromodulators like epinephrine, and create a neurochemical context for increased energy and mental acuity throughout the day.
10. High Alertness for Strategy
Utilize states of high alertness for tasks that involve strategy implementation, where you already know how to do something and need to execute, such as linear tasks, calculations, or responding to emails.
11. Silence for High Alertness
If you are feeling very alert or ‘keyed up,’ work in complete silence and eliminate background noise (e.g., turn off internet, phone) to quiet autonomic arousal and suppress distractions, which is optimal for focused learning and linear tasks.
12. Background Noise for Focus
If you are experiencing low arousal, tiredness, or sleepiness, some background chatter or noise can help elevate your level of autonomic arousal and alertness by engaging the salience network.
13. Fasted/Low-Carb for Alertness
Utilize fasted states and low-carbohydrate states to increase alertness, as carbohydrates tend to induce sleepiness, while fasting promotes a state of wakefulness.
14. Consider Salt Intake
If you drink a lot of caffeine or are fasting, consider drinking water with a little bit of sea salt or typical table salt to prevent low sodium, which can cause shakiness, inability to think, or headaches (consult a doctor, especially if you have hypertension).
15. Low-Carb Lunch for Focus
Eat a low-carbohydrate meal (e.g., meat, salad, nuts, fats, fruits, vegetables) for lunch to maintain focus and alertness throughout the afternoon.
16. Avoid Hot Lunch
Avoid eating hot food for lunch if you want to maintain alertness, as hot food can cause post-lunch sleepiness.
17. Shift Work for Afternoon
Around 2-3 p.m. when feeling groggy, shift from tasks requiring high cognitive load and linear analysis to more mundane tasks that require less cognitive effort and can be done out of sequence, like answering emails.
18. Afternoon Non-Sleep Deep Rest
Perform a non-sleep deep rest (NSDR) protocol (e.g., 10-30 minute yoga nidra or hypnosis) in the afternoon to restore cognitive and physical energy, enhance plasticity, and aid in falling asleep later, rather than relying on more caffeine.
19. Creative Work in Calm
Engage in creative work, such as exploring novel configurations of existing elements or brainstorming ideas, in the afternoon when in a clear, calm, and focused regime, often after an NSDR session, as this state facilitates creative discovery.
20. Separate Creative Stages
Recognize creativity as a two-part process: creative discovery (facilitated by relaxed or slightly sleepy states) and linear implementation (requires high alertness). Conceive ideas in relaxed states, but revisit them later for deliberate, linear implementation during highly focused states.
21. Evening Light Exposure
Get light exposure in the evening (by going outside or using bright artificial lights) to slightly delay your circadian clock, which helps prevent waking up too early and maintains a regular 24-hour sleep-wake cycle.
22. Dim Lights for Sleep
Minimize bright light exposure, especially overhead, in the evening (from about 10 p.m. to 4 a.m.) by dimming lights and screening off devices to promote falling asleep and ensure a good night’s sleep.
23. Carbohydrate-Rich Evening Meal
Eat a more carbohydrate-rich evening meal (e.g., pasta, rice, vegetables, eggs, fish, or chicken) to facilitate calmness and sleepiness, stimulate tryptophan release, and replenish glycogen if you exercised earlier in the day.
24. Anticipate Late-Night Alertness
Anticipate a natural peak in alertness and activity about an hour before bedtime, which is a normal circadian blip, rather than confusing it with insomnia or anxiety; use this time for mundane tasks or organizing for the next day.
25. Don’t Trust Late-Night Thoughts
If you wake up in the middle of the night with looping thoughts, do not trust any thinking that occurs during those wee hours for creative insights or linear implementation.
26. NSDR for Mid-Night Waking
If anxious or experiencing looping thoughts after waking in the middle of the night, use a non-sleep deep rest (NSDR) protocol, such as a hypnosis app or yoga nidra script, to help turn off the thinking and fall back asleep.
27. Leverage Autonomic Tools
Use tools like cold showers, ice baths, or super oxygenation breathing (e.g., Wim Hof type breathing) to increase alertness when needed, and warmer baths to promote calmness (always research and understand associated cautionary notes).
28. Vitamin D3 K2 Supplement
Consider supplementing with Vitamin D3 K2, as D3 is essential for brain and body health, and K2 regulates cardiovascular function and calcium, with many people being deficient in D3 even with sun exposure.
29. Black Coffee/Mate for Focus
Drink black coffee or mate (a high-caffeine drink) after the two-hour delay from waking to enhance alertness and focus.
6 Key Quotes
Plasticity is not the goal. Plasticity is never the goal. Plasticity is simply a state or a capacity for our nervous system to change.
Andrew Huberman
The trigger for plasticity and learning occurs during high focus, high alertness states, not while you're asleep. And the focus and alertness are both key because of the neurochemicals associated with those states. But the actual rewiring and the reconfiguration of the brain connections happens during non-sleep deep rest, which we'll talk more about as always, and deep sleep.
Andrew Huberman
When you are very alert, the best situation for learning is going to be silence. It's going to be complete quiet. If you are low arousal and you're tired and you're kind of sleepy, a lot of people find that having some background chatter and some background noise can help elevate their level of autonomic arousal.
Andrew Huberman
Creativity is a very interesting state of mind in which we're taking existing elements, things that we already know, and rearranging them in ways that are novel.
Andrew Huberman
I don't trust anything I think about when I wake up in the middle of the night, any of it.
Andrew Huberman
The word midnight was literally supposed to mean midnight. We, meaning all of us, were meant to go to sleep and wake up with the setting and arising of the sun.
