- Properly controlling the mechanical and chemical state of organs can improve brain function and overall health.
- Optimizing the chemistry of organs can improve the immune system and accelerate healing.
LDB (Lung-Diaphragm-Brain) Dialogue
The Lung-Diaphragm-Brain (LDB) Dialogue is a powerful system that involves the mechanical movement of the diaphragm and its impact on breathing. Understanding this system can lead to increased awareness of our breathing and the ability to leverage it for brain function. Key points include:
- The lungs consist of millions of tiny sacs called alveoli, which can fill up or deflate.
- The diaphragm, a skeletal muscle shaped like a dome, sits below the lungs and can be voluntarily controlled.
- The interaction between the diaphragm and lungs affects how our brain functions.
- The LDB Dialogue involves the mechanical movement of the diaphragm and its impact on breathing.
- Understanding these mechanical changes can lead to increased awareness of breathing and the ability to leverage it for brain function.
- This system is powerful and can be harnessed to shift the brain in the desired direction.
Protocols 2, 3, 4: Control Heart Rate With Breathing
The most profound aspect of the topic is that the heart rate can be controlled by changing the way we breathe.
- Inhaling causes the heart to physically enlarge and slows down the flow of blood.
- Quick exhales have a different effect on the heart rate.
- The brain sends signals to speed up the heart rate during inhales and slow it down during exhales.
- Emphasizing exhales can promote a sense of calm and can be achieved through a physiological sigh.
- Breathing techniques can optimize brain-body function and lead to relaxation or increased alertness.
- Box breathing, with equal durations of inhaling, holding, exhaling, and holding again, can regulate brain function.
- Protocols 2, 3, and 4 in the Huberman Lab Podcast #30 explore the relationship between breathing and heart rate control.
Sensing Lung Pressure: Piezo Receptors
Piezo receptors, also known as pressure receptors, inform the brain about pressure in tissues. The lungs have piezo two receptors that react to lung filling and send information to the brain. This mechanical sensing is studied in Ardem Patapoutian's lab at the Scripps Institute.
- Piezo receptors are pressure receptors that inform the brain about tissue pressure.
- The lungs have piezo two receptors that react to lung filling.
- These receptors send information to the brain about lung fullness.
- Ardem Patapoutian's lab at the Scripps Institute studies mechanical sensing in the lungs, heart, and diaphragm.
Carbon Dioxide, From Air to Blood
The exchange of carbon dioxide and oxygen is essential for brain-body function and health. Neurons in the brain detect high levels of carbon dioxide, triggering the impulse to breathe and intake more oxygen. The balance between carbon dioxide and oxygen is crucial for tissue well-being. Elevated carbon dioxide levels can cause panic responses. The exchange of oxygen molecules occurs in the lungs, passing into the bloodstream through the alveoli and capillaries. This exchange happens through inhalation and exhalation, connecting the heart, vascular system, blood, air system, respiration system, and breathing.
Protocol 5: Alert While Calm
Protocol 5: Alert While Calm is a breathing technique that optimizes brain-body function and increases alertness. Key points include:
- The technique involves taking 25-30 quick breaths, exhaling all the air, and holding the breath for 15-30 seconds.
- This changes the chemistry of the bloodstream and triggers a reflex for longer breath-holding.
- The technique should be practiced with caution and is not recommended for free diving.
- It demonstrates how modulating the mechanics of the diaphragm and lungs can impact brain function.
- The goal is to achieve a state of alertness and calmness simultaneously, without the jittery side effects of stimulants.
- Breathwork practices can optimize brain-body function and health, but there is no one-size-fits-all protocol.
- Changing the way we breathe can affect immune system function and inflammation response.
- There is a particular reflex that can be beneficial during times of extreme stress.
Baroreceptors: Hering-Breuer Reflex
The Hering-Breuer reflex, involving baroreceptors, is a crucial factor in the brain's decision-making process regarding breathing. It reduces the desire to breathe when the lungs are inflated and triggers the gasp reflex sooner when exhaling all the air and holding the breath. This reflex can be applied in various situations, such as exercise and stress modulation. Taking a deep breath before going underwater helps delay the need for air.
Gut Volume & The Desire to Open Your Mouth
The connection between gut volume and the desire to open your mouth is explored in this topic. Key points include:
- The human body consists of various tubes, including the gut, which communicates with the brain about its mechanical pressures and chemical status.
- When the gut fills up with food or fluid, it triggers the desire to open the mouth and begin digestion.
- The gut contains sphincters that control the flow of food, and pressure receptors send signals to the brain to stop eating when the gut is full.
- Expanding the gut, as done in competitive eating, can override the signal to stop eating, but it is not recommended.
- Neurons in the gut send signals to the brain to shut down the desire to eat when the gut is full.
- The sense of fullness or lack of fullness in the gut plays a significant role in our desire to eat, and understanding this can be improved.
Protocol 6: Enhancing Gut-To-Brain Communication, Fasting
Protocol 6: Enhancing Gut-To-Brain Communication, Fasting

- Intermittent fasting involves fasting for 12 to 16 hours within a 24-hour cycle
- Intermittent fasting has positive effects on liver health, brain health, and autophagy
- Feeling an empty stomach is just a signal from the gut to the brain and can be overridden
Intestines, Fatty Acids, Amino Acids & Sugar
The intestines play a crucial role in communicating with the brain, triggering hunger or stopping eating based on signals from GLP1R and GPR65 neurons. These neurons sense the stretch, movement, and nutrients in the digestive tract. Fatty acids, amino acids, and sugars released from digested food stimulate gut neurons to send signals to the brain, regulating appetite and food preferences. The taste of nutrients is irrelevant, as gut neurons still signal to the brain even when the mouth is numb.
Protocol 7: Reducing Sugar Cravings with Specific Amino Acid Nutrients
The protocol for reducing sugar cravings involves ingesting a small amount of glutamine mixed with full-fat cream. This provides fat and amino acids to the neurons in the gut and intestine, reducing the brain's signal for more sugar cravings. It is recommended to limit or eliminate simple sugars and incorporate high omega-3 foods or supplements for overall health benefits. Gut chemistry is important for brain function and the immune system, especially for individuals with autoimmune conditions.
Gut Acidity (Is Good)
Maintaining the proper acidity of the gut is crucial for its proper functioning.
Key points:

The speaker suggests focusing on fermented foods and maintaining a slightly more acidic stomach environment instead of relying on commercial enterprises for comprehensive gut analysis.
Nausea: Happens in Your Brain; Area Postrema
Nausea, a brain-mediated response, occurs when substances travel from the stomach or intestines to the brain. The blood-brain barrier protects the brain, but small openings allow chemicals to enter, guarded by neurons. The area postrema, located in the brainstem, triggers nausea and vomiting reflexes. It responds to blood chemistry and consciousness, causing nausea when negative stimuli are present. Nausea serves as a protective mechanism to expel harmful substances, and vomiting prevents absorption of toxins. Strategies can be used to alleviate symptoms of nausea, such as excessive salivation.
