Huberman Lab Essentials; Neuroplasticity (0s)
- Neuroplasticity is an incredible feature of the nervous system that allows it to change itself, even in ways that we consciously decide, making it unique compared to other tissues like the liver and spleen (24s).
- The cells in other tissues can make changes, but the nervous system has the ability to direct its own changes in ways that we believe or are told will serve us better (47s).
- The goal of optimizing the brain is not to achieve plasticity itself, but to figure out how to access plasticity and then direct it toward particular goals or changes that we would like to achieve (1m36s).
- Andrew Huberman, a professor of neurobiology and Ophthalmology at Stanford School of Medicine, will share his typical routines and tools for optimizing the brain, as many have asked for concrete examples of what he does and when (1m17s).
- The discussion will focus on answering common questions about how to optimize the brain and what it means to optimize the brain (1m4s).
- The brain's ability to change itself through conscious thought or feedback from another person is a key aspect of neuroplasticity (29s).
- The nervous system's ability to change itself is not limited to unconscious changes, but can also be directed through conscious thought and decision-making (51s).
Types of Neuroplasticity (1m50s)
- There are several forms of neuroplasticity, which can be categorized into short-term, medium-term, and long-term plasticity (2m8s).
- Short-term plasticity refers to temporary changes that an individual wants to achieve in the moment or day, but not necessarily hold on to forever, such as using a protocol like coffee or breathing to become more alert at an unusual time of day (2m28s).
- Examples of short-term plasticity include waking up earlier than usual to catch a flight and using a protocol to become more alert, with the expectation of discarding the need for this change when returning home (2m57s).
- Medium-term plasticity involves changes that an individual wants to make for a short period, such as learning routes and towns while on vacation, with the intention of discarding the information afterwards (3m1s).
- Long-term plasticity is the most common goal when optimizing the brain, involving changes that people want to make so that their brain reflexively works differently, such as learning a new language or skill (3m23s).
- Long-term plasticity is often the "Big Goal" that people strive for, such as wanting to know how to speak a language, perform a skill, or feel a certain way (3m29s).
Autonomic Arousal, Sleep (3m46s)
- Neuroplasticity and optimizing the brain rely on a deeper foundation of autonomic arousal, which governs plasticity and all aspects of life, including the cycle of being asleep and awake for parts of the 24-hour cycle (3m46s).
- The trigger for plasticity and learning occurs during high focus and high alertness states, not while asleep, due to the associated neurochemicals (4m8s).
- Focus and alertness are key for triggering changes in the brain, while the actual rewiring and reconfiguration of brain connections happen during non-sleep deep rest and deep sleep (4m19s).
- The autonomic arousal system, a network of neurons in the brain and body, plays a crucial role in waking and alertness, and accessing this system is necessary for optimizing the brain and accessing plasticity (4m39s).
- Inability to access the autonomic arousal system or sleep well can hinder access to plasticity and the ability to rewire the brain, as the actual configuration of brain connections occurs during rest and sleep (4m50s).
- Waking up feeling tired and groggy can be due to not matching one's hardwired needs of going to bed and waking up at optimal times, but neuroplasticity can help optimize wakefulness with the right tools (5m8s).
- Exposure to sunlight in the first 30 minutes of the day helps wakefulness by affecting the connections between melanopsin cells, which detect bright light, and the circadian clock, which are plastic throughout the lifespan (5m48s).
- The circuit between the circadian clock and the adrenals triggers the release of cortisol in the morning, helping to wake people up, especially when combined with viewing light (6m22s).
- Delaying caffeine intake for the first two hours after waking allows the neural circuit between the circadian clock and cortisol release in the adrenals to be reinforced, and then caffeine can be used to get a natural lift in alertness and focus (6m37s).
- Hydrating first thing in the morning is essential, as even slight dehydration can cause headaches, photophobia, and increased vulnerability to migraines, and drinking water before consuming caffeine is recommended (7m18s).
- Drinking water, black coffee, or a high-caffeine drink like mate can be done two hours after waking up, allowing the circuits between the eye, circadian clock, and adrenals to function in a particular way before adding caffeine for extra alertness (7m46s).
Alertness, Morning & Work Bout (8m11s)
- People who wake up quickly and feel alert can immediately start their learning or work bout, but this is not the case for everyone, as some individuals take time to become alert and focused in the morning (8m13s).
- The brain functions best in states of high alertness for strategy implementation, which is ideal for tasks that require focus and a well-rested mind (8m36s).
- High alertness levels are beneficial for tasks that involve implementing a strategy that is already known, rather than learning new information (9m9s).
- For individuals who are not naturally alert in the morning, it may be more effective to use this time for organizing thoughts and getting ready for the day, rather than responding to emails or performing calculations (9m15s).
- Mid-morning is typically when many people achieve their peak alertness and focus, making it an ideal time for tasks that require concentration and mental clarity (9m31s).
- When feeling too keyed up, silence and quiet are helpful for learning, as a particular circuit related to the basal ganglia, called the "Go" circuit, gets triggered more easily, promoting action over rational thought and planning (9m55s).
- The basal ganglia are involved in a reciprocal loop of communication with the cortex, facilitating "go" or action, and the molecule dopamine triggers the activation of "go" by binding to the D1 receptor, making us biased toward action (10m41s).
- The "nogo" pathway, which suppresses action, involves dopamine binding to the D2 receptor, and it's not possible to consciously decide which receptors to activate, but rather, it's influenced by states of mind and body (11m7s).
- There are three levels of autonomic arousal or alertness that bias us toward "go" or "nogo", and being very alert can make us prone to action but not good at suppressing action, while being low arousal and tired can make background noise helpful for elevating autonomic arousal (11m31s).
- The best situation for learning is silence when very alert, but for most people, 3 hours after waking is the period when they're most alert, and background chatter and noise can be helpful when feeling tired and sleepy (12m29s).
- The D1 and D2 receptors are involved in the "go" and "nogo" pathways, respectively, and understanding how they work can help in facilitating or suppressing action, and ultimately, in optimizing learning and creativity (11m12s).
- Exercising early in the day triggers the release of epinephrine and other neuromodulators, leading to heightened levels of arousal and mental acuity in the late morning and afternoon (13m13s).
- Early morning exercise biases individuals towards waking up earlier and sets a neurochemical context that triggers activation of the "go" pathway, making it easier to engage and take action (13m39s).
- Exercising within an hour of waking, or no later than 3 hours after waking, can provide more energy throughout the day (13m49s).
- A morning routine that includes early morning exercise, delayed caffeine consumption (2 hours after waking), and morning light exposure can be beneficial for focused learning (14m4s).
- This routine involves exercising in the first hour or ideally within the first three hours of waking, followed by a focused learning session (14m6s).
- Typically, eating a meal, especially a low-carbohydrate meal with choline content, helps maintain focus throughout the day, with the first meal usually eaten around midday (14m22s).
- Around 2:00 or 3:00 p.m., a natural dip in alertness occurs, making it more suitable for tasks that require less cognitive load and can be done out of sequence, such as answering emails (14m48s).
- To combat the afternoon dip, hydrating and doing a non-sleep deep rest (NSDR) protocol, such as a 10- or 30-minute Yoga Nidra type protocol, is beneficial, usually done around 4:00 p.m. (15m18s).
- Engaging in NSDR helps avoid disrupting sleep schedules and allows for a second bout of learning or work, which can involve linear analysis, numerical work, or learning something new (15m53s).
- The second learning bout is different from the morning one, as it falls under the clear common focus regime, and is often used for creative type work, without ingesting caffeine to ensure a good night's sleep (16m35s).
Creativity: Exploring vs. Implementation (16m37s)
- Creativity is a state of mind where existing elements are rearranged in novel ways, and it consists of two parts: creative discovery mode and linear implementation mode (16m37s).
- In creative discovery mode, individuals shuffle things around in a relaxed way, being playful or exploring different configurations, which is facilitated by being relaxed and almost sleepy (16m52s).
- The linear implementation mode involves taking an idea or design and creating something robust and concrete, which is a more structured and goal-oriented process (17m2s).
- Substances are often used to access creative states, but they can be problematic as they may help with creative brainstorming mode but hinder linear implementation mode (17m42s).
- The state that favors creativity and creative learning may vary from person to person, with some people being more creative in the morning and others in the afternoon or later (18m21s).
- Alertness is generally associated with good linear implementation, goal pursuit, and strategy implementation, while a more relaxed state is better suited for novel configurations of existing elements, which is creativity (18m32s).
- The non-sleep deep breath mode or sleep can be a good time for creativity, as it allows for a more relaxed and sleepy state that facilitates novel configurations of existing elements (18m50s).
- Psychedelics can cause sensory blending, where people report being able to smell colors or hear trees, but this is not a creative process in itself (19m6s).
- The essence of a creative process involves new ways of configuring things that lead to a deeper or novel understanding, which sensory blending alone cannot accomplish (19m26s).
- There are clinical trials underway that leverage psychedelics towards particular clinical goals, such as treating depression and trauma, under the supervision of a psychiatrist (19m45s).
- Psychedelics may have important roles in a clinical context, provided they are used legally and safely, but they are not considered a primary tool for accessing creative states (20m4s).
- The creative process is a two-stage process, involving a period of nonlinear expansion of concepts, followed by deliberate linear implementation (20m21s).
- Nonlinear expansion of concepts is best done in a relaxed state, while deliberate linear implementation requires high levels of alertness and focus (20m52s).
- Creative works can be conceived during relaxed states, but their implementation requires high levels of alertness (20m59s).
- Getting sunlight in the evening accomplishes two things: it ensures not waking up too early and helps maintain a regular 24-hour cycle, which is important for optimizing learning and performance by providing predictability to how the mind works (21m14s).
- Morning light advances the body's clock, making the system want to get up earlier, while evening light delays the clock, allowing for a consistent sleep schedule (21m47s).
- To maintain a consistent circadian rhythm, it's essential to get both morning and evening light, which helps the body want to go to sleep and wake up at the same time every day (21m54s).
- In the evening, it's recommended to minimize light exposure, especially overhead bright light, from around 10:00 p.m. to 4:00 a.m. to favor a good night's sleep (22m24s).
- A carbohydrate-rich evening meal can facilitate calmness and sleepiness by stimulating the release of tryptophan and replenishing glycogen (22m41s).
- Carbohydrate-rich foods can help achieve a state of calmness and sleepiness, which is beneficial for a good night's sleep, whereas fasting and low-carbohydrate states facilitate alertness (22m52s).
- The peak output of the circadian clock for wakefulness occurs very late in the day, with a brief blip of release of peptides and other substances from the sleep centers in the brain signaling the peak of alertness and wakefulness about an hour before bedtime (23m57s).
- This peak in alertness can often lead to stress and worry about not being able to sleep, but anticipating this peak and using it to get organized for the next day can be helpful (24m10s).
- Engaging in mundane tasks that require almost zero effort can also be beneficial during this time (24m21s).
- The natural sleep-wake schedule, also known as the natural pattern, is to go to sleep and wake up with the setting and rising of the sun, but artificial lights have deviated from this pattern (24m50s).
- Waking up at 3:00 a.m. or 4:00 a.m. doesn't necessarily mean there's something wrong, but rather that the individual may have gone to bed much later than they naturally would have wanted to (24m59s).
- The autonomic nervous system has an asymmetry that makes it easier to delay sleep time than to accelerate wake-up time, leading many people to push through into the late hours of the evening and night (25m7s).
- Going to bed much later than the natural sleep time can lead to running out of melatonin, causing individuals to wake up in the middle of the night (25m43s).
- When waking up in the middle of the night and feeling anxious, it's helpful not to trust any thoughts and to use non-sleep deep rest protocols to go back into sleep (25m58s).
- Non-sleep deep rest protocols can be useful in turning off looping thinking in the middle of the night and falling back asleep (26m16s).
- A daily schedule includes two 90-minute work bouts, one for learning and work in the morning and another for creative work in the afternoon, with the remaining hours occupied by tasks such as email, meetings, and attending to colleagues and students (26m25s).
- The two 90-minute bouts are focused on expanding mental capacities and stretching and growing what one is able to do on a regular basis, with the goal of optimizing brain function (27m0s).
- It is recommended to slot in one or two 90-minute brain optimization segments per day, amidst other obligations, in an intelligent way that is anchored to one's biology (27m18s).
- These sessions should be optimized to get the most out of them, using various tools and strategies that have been discussed (27m37s).
- The key is to implement these brain optimization segments in a way that works with one's schedule and other demands, such as school or family obligations (27m14s).
- When using any tool to modulate or measure the nervous system, it's essential to consider whether it will increase or decrease autonomic arousal, making you more alert or calm, and whether that state matches your learning goals (27m44s).
- The most valuable internal tool for learning is recognizing and tailoring your alertness and calmness to specific activities, as it's reciprocal, meaning certain activities like exercise or food can impact your autonomic arousal and alertness (28m12s).
- Becoming an observer of your own system and recognizing what works for you is crucial, as there are two bins of tools for optimizing learning: those anchored in biological mechanisms and more subjective tools like visualization or music (28m52s).
- Tools anchored in biological mechanisms are certain and have been discussed previously, while subjective tools vary from person to person, such as visualization or music, which can have different effects on individuals (29m2s).
- Volume is a universal factor, with loud music tending to wake people up and soft music not having the same effect (29m27s).
- It's essential to think about the non-negotiable elements of your 24-hour cycle, including periods of wakefulness and sleep, and leverage them to avoid fighting an uphill battle to wake up or sleep at the wrong times (29m39s).
- Understanding your individual biology and wiring, including whether you're more geared towards parasympathetic calm states or sympathetic alert states, is crucial for setting goals and using the right tools (30m25s).
- Recognizing that people have different autonomic nervous systems and wiring, some being more "go-go-go" and others calmer, is essential for tailoring your approach to your individual needs (30m21s).
