A System of Touch (Somatosensation)
The somatosensory system is responsible for understanding touch and physical sensations on our body.
Key points:
- Neurons in our skin and deeper layers respond to stimuli like pressure, heat, cold, and vibration.
- Electrical signals from sensors are sent to the spinal cord and brain for interpretation.
- Pain is a complex term in neuroscience with subjective and mental components.
Pain and Injury are Dissociable
Pain and injury can be dissociated, with examples of tissue damage without pain perception and pain without actual tissue damage. This highlights the power of the mind and the specificity of pain perception. Our higher-level cognitive functions can interpret and perceive pain based on external cues. Principles from the pain system can help differentiate between injury and pain. The podcast will cover protocols to eliminate pain from both the injury site and through mental mechanisms.
Objective versus Subjective Control of Experience
The objective versus subjective control of experience is explored in this video. The speaker highlights the role of love in modulating the pain response and the impact of different types of connections with romantic partners on physical pain. The plasticity of perception and its effect on emotional pain are also discussed.
- Love can modulate the pain response.
- Different types of connections with romantic partners can alleviate physical pain.
- The plasticity of perception plays a role in emotional pain.
Plasticity of Perception
The plasticity of perception, specifically focusing on pain, is discussed in the video. Examples of extreme cases are provided to illustrate the topic.
- Plasticity of perception refers to the brain's ability to adapt and change its perception of sensory information.
- Pain perception can be influenced by various factors, including expectations, emotions, and past experiences.
- The brain can alter its perception of pain based on the context in which it occurs.
- Extreme cases, such as individuals with congenital insensitivity to pain, highlight the plasticity of pain perception.
- Understanding the plasticity of perception can have implications for pain management and treatment.
Lack of Pain Is Self-Destructive; So Is Excessive Pain
The relationship between pain and a specific sodium channel mutation is explored in this video. The mutation in sodium channel 1.7 can result in individuals experiencing either no pain or excessive pain. Children born without this sodium channel experience no pain, leading to self-destructive behaviors and joint damage. Individuals with a mutation that produces an excess of this sodium channel feel extreme pain even from subtle stimuli. However, there are drug treatments available to block this sodium channel and provide relief. The sensitivity to pain may have a genetic basis, but there are also ways to reduce pain and recover from injuries. Our brain has maps of our body surface that are related to pain perception and recovery.
Homoculous, Ratonculous, Dogunculus
- Homunculus, ratunculus, and dogunculus are terms used to describe the representation of the body surface in a rat and a dog.
- The nomenclature is based on scaling the representation to match sensitivity.
“Sensitivity” explained
The density of receptors in different body parts determines their sensitivity. The brain has more representation for body parts with higher receptor density, such as the lips, fingertips, genitalia, and eyes. Two-point discrimination can be used to determine sensitivity, with higher receptor density leading to better discrimination. Areas with denser receptors are more sensitive to pain and have more support cells that contribute to inflammation. Injured areas with low sensitivity before the injury tend to experience less pain and heal more slowly.
Inflammation
- Inflammation is a natural response for tissue repair but can be harmful when uncontrolled
- Ways to modulate inflammation after tissue injury or intense exercise are discussed
- The podcast briefly explains the neurobiology of somatosensation and the relationship between peripheral and central maps
- Phantom limb pain is used as an example
Phantom Limb Pain
Phantom limb pain is a phenomenon where amputees still feel pain in their missing limb. The brain's intact representation of the limb causes increased activity levels in circuits. Lack of proprioceptive feedback contributes to this. Ramachandran has developed a top-down modulation solution.
- Phantom limb pain occurs when amputees feel pain in their missing limb
- The intact representation of the limb in the brain causes increased activity levels in circuits
- Lack of proprioceptive feedback contributes to the heightened activity
- Ramachandran has developed a top-down modulation solution to address this issue
Top-down Relief of Pain by Vision
The ability to use the brain and senses to control pain in the body is a learnable skill that can benefit everyone. By using visual imagery and mirrors, individuals missing a limb can experience relief from phantom pain. This technique allows for real-time remapping of the representation of the hand, providing immediate relief. The Ramachandran studies demonstrated the profound effects of using the brain to control perceptions of the body. Visual imagery can drive fast plasticity in the brain, leading to top-down relief of pain. This was demonstrated through a study where participants used a mirror box without looking into it, resulting in no remapping. Therefore, visual experience is necessary for this pain relief mechanism.
Key points:
- Using visual imagery and mirrors can provide relief from phantom pain in individuals missing a limb
- Real-time remapping of the representation of the hand allows for immediate relief
- The Ramachandran studies showed the profound effects of using the brain to control perceptions of the body
- Visual imagery drives fast plasticity in the brain, leading to top-down relief of pain
- Visual experience is necessary for this pain relief mechanism
From Deaf to Hearing Sounds
- The cochlear implant is a device that helps deaf individuals hear sounds
- Some people find the cochlear implant disruptive while others benefit from it
- The brain is adaptable and can make sense of sensory inputs
- Pain is a perceptual experience
Pain Is In The Mind & Body
The relationship between pain and the mind and body is explored in this video. The concept of neuroplasticity is discussed, highlighting how deliberate actions can promote it. However, the speaker questions the effectiveness of certain practices. Studies from the '90s and 2000s are mentioned, providing protocols for overcoming motor injury.
- Pain and the mind and body are interconnected
- Neuroplasticity can be promoted through deliberate actions
- Questioning the effectiveness of certain practices
- Studies from the '90s and 2000s provide protocols for overcoming motor injury
Recovering Movement Faster After Injury
Injuries that limit movement can lead to muscle atrophy due to inactive nerves. Restricting use of the uninjured limb and promoting activity in the injured limb can accelerate recovery. This enhances brain plasticity and balances motor imbalances. Avoid further injury and restrict the uninjured pathway if motor signals are not reaching the limbs. The balance between both sides of the body is crucial for faster recovery. Overwork the injured side and restrict activity of the healthy side. This concept is similar to ocular dominance plasticity.
Don’t Over Compensate
The most profound aspect of the topic "Don't Over Compensate" is the importance of avoiding overcompensation when dealing with pain or injury.
Key points:
- The brain has limited space for sensory and motor functions, so it's crucial to avoid overcompensating with unaffected areas when injured.
- Instead, focus on targeted exercises for the injured area while restricting the use of the healthy limb.
- This should be done for one to two hours a day, not necessarily all day.
- By following this approach, it accelerates the recovery of function and promotes neuroplasticity.
- This principle applies not only to limb injuries but also to traumatic brain injuries.
- It is important to note that the speaker is not a neurologist.
Concussion, TBI & Brain Ageing
Concussion recovery and understanding traumatic brain injury (TBI) is important for athletes, accident victims, and general brain aging. Key points include:
- TBI can result from various causes and has different symptoms for each individual.
- Common symptoms include headaches, sensitivity to light, sleep disruption, trouble concentrating, and mood issues.
- Prevention is crucial, as the severity of TBI varies.
- The brain has a greater capacity for self-repair in early life, but TBI can occur at any age.
- Athletes and individuals in certain professions are at a higher risk of experiencing TBI.
- The brain's repair system is primarily centered around the lymphatic system.
The Brain’s Sewage Treatment System: Glymphatic Clearance
The brain's sewage treatment system, known as glymphatic clearance, is most active during sleep, particularly during slow-wave sleep. Adequate rest and sleep are crucial for the glymphatic system to function properly and clear away debris. To optimize the repair and functioning of the glymphatic system, it is important to prioritize getting deep sleep, which mainly occurs in the early part of the night. Additionally, sleeping on one side, rather than on the back or stomach, can activate the glymphatic clearance system.
Body Position & Angle During Sleep
- Sleeping on one's side or with feet slightly elevated improves the efficiency of the glymphatic system, which clears debris from the brain.
- Sleeping on one's back or stomach is not ideal.
- Using a thin pillow under the ankles can enhance sleep quality.
- A specific form of exercise can improve glymphatic system function.
Types of Exercise For Restoring & Maintaining Brain Health
Exercise, specifically low-level cardio known as Zone 2 cardio, for 30 to 45 minutes, three times a week, can improve the clearance of debris after injury and enhance the flow of the glymphatic system. This type of exercise, such as fast walking, jogging, or cycling, is not focused on improving fitness levels but rather on promoting brain health. It is particularly beneficial for individuals with traumatic brain injury (TBI) and can also be beneficial for aging individuals.
Key points:
- Zone 2 cardio, like fast walking, jogging, or cycling, for 30-45 minutes, 3 times a week, improves debris clearance and enhances the glymphatic system.
- This exercise is not about fitness, but about promoting brain health.
- It is beneficial for individuals with TBI and aging individuals.
- These exercises can be combined with weight training and cardio.
- The mechanism behind these exercises is not fully understood.
Ambulance Cells in The Brain
Aquaporin-4, a molecule related to glial cells in the brain, plays a crucial role in bridging connections between neurons, synapses, and the blood system. Glial cells, specifically astrocytes, contribute to the glymphatic system, which removes waste from the brain. Activating this system is important for brain health. Low-level walking, Zone 2 cardio during the day, and slow-wave sleep at night can help activate it. This information is relevant for anyone interested in brain longevity.
True Pain Control by Belief and Context
Our interpretation of sensory events greatly affects our experience of pain. Factors such as adrenaline release during combat sports and the anticipation of pain relief can alter pain perception. The placebo effect and belief also play a significant role in pain experience, impacting both negative and positive stimuli. A study at Stanford University showed the influence of belief on pain perception.
Romantic Love and Pain
Romantic love has the power to reduce pain perception and increase pain tolerance. The level of infatuation and obsession with the loved one determines the extent of this effect. Highly obsessed individuals can experience significant pain reduction, especially in the early stages of a relationship. This pain modulation is similar to the top-down modulation observed in mirror box experiments. The perception of pain is highly influenced by the pain system, as shown by the example of the nail through the boot. The somatosensory system is interconnected with the autonomic nervous system, which may contribute to the pain reduction experienced during romantic love.
Dopaminergic Control of Pain
Dopamine release, associated with obsessive love, has the potential to reduce the unpleasantness of physical pain. Emotional and physical pain are intertwined, and dopamine may play a role in blunting pain. Chasing dopamine release could be a potential treatment for chronic and acute pain.
- Dopamine release is linked to the obsessive type of love and infatuation
- This type of love has the potential to reduce the unpleasantness of physical pain and other aspects of life
- Emotional pain and physical pain are closely intertwined
- Dopamine release may play a role in blunting pain
- Chasing dopamine release could be a potential treatment for chronic and acute pain
Acupuncture: Rigorous Scientific Assessment
Acupuncture, a practice being rigorously studied at top universities like Harvard Medical School, has shown to both exacerbate and relieve pain through specific neural pathways. It has been found beneficial for gastrointestinal issues and is supported by peer-reviewed studies. The National Institutes of Health now has a division dedicated to complementary health, including acupuncture, indicating a shift in perception towards these practices.
Key points:
- Acupuncture reveals the connection between the somatosensory system and the autonomic nervous system.
- It provides relief for referred pain and is based on the somatotopic map in the brain.
- Acupuncture can modulate pain and inflammation, but intense stimulation can increase inflammation.
- The effects of acupuncture depend on the intensity and location of stimulation, with different pathways being activated.
- Acupuncture can activate the adrenals and the brain, releasing norepinephrine and epinephrine, which can have short-term anti-inflammatory effects but can also trigger anxiety pathways.
- Overall, the effects of acupuncture are complex and require further research.
Vagus Activation and Autonomic Control of Pain
The activation of the vagus nerve plays a crucial role in controlling pain and promoting healing. Key points include:
- Dopamine and norepinephrine can activate the vagus nerve, reducing inflammation and blunting pain response.
- The autonomic nervous system is involved in this process, regulating alertness and calmness.
- Body surface maps can stimulate the autonomic nervous system, influencing pain and healing.
- Certain pathways can be pro-inflammatory when stimulated.
- Understanding inflammation is essential for managing pain and promoting healing.
Inflammation, Turmeric, Lead and DHT
Inflammation is a necessary process for healing from injuries, but chronic inflammation can be harmful. Turmeric has anti-inflammatory properties, but it can be contaminated with lead. Turmeric can also negatively affect dihydrotestosterone levels in men, leading to a decrease in libido. Caution should be exercised when using turmeric. Overall, inflammation should be regulated and understood.

The most profound aspect of the topic is the role of adrenaline in the body's response to stress and physical threats.
Key points:
- Wim Hof breathing involves hyperventilating and breath holds, releasing adrenaline from the adrenals.
- Stress helps counter infection by liberating killer cells in the body.
- Adrenaline and inflammation are adaptive responses that enhance performance in challenging situations.
- Practices like Wim Hof breathing, cold showers, and ice baths can increase adrenaline levels.
- These practices provide actionable tools to control pain and heal faster.
Protocols For Accelerating Tissue Repair & Managing Pain
The most profound aspect of the topic is the importance of protocols for accelerating tissue repair and managing pain.
Key points:
- Developed in consultation with Kelly Starrett, an expert in movement and tissue rehabilitation.
- Consult with a physician before adopting or removing any protocols.
- Importance of sleep for tissue rehabilitation, with a minimum of eight hours in bed per night.
- At least eight hours of immobility can also be beneficial.
- Deep rest protocols for improving sleep.
- 10-minute walk per day for promoting tissue clearance.
- These protocols facilitate glymphatic clearance and tissue repair.
Ice Is Not Always Nice (For Pain and Injury): Sludging, Fascia, Etc.
The use of ice for pain and injury may not be as beneficial as previously thought. Here are the key points:
- Ice can temporarily numb the injury site and reduce pain, but it can also cause sludging in the blood and lymphatic tissue, leading to clotting and increased inflammation.
- This can hinder the movement of cells responsible for repairing the injury.
- Heat has been found to be beneficial for healing as it improves tissue viscosity and promotes the clearance and perfusion of fluids, aiding in the healing process.
- The use of ice packs may primarily provide a placebo effect for pain relief rather than directly aiding in healing.
- Heat, mobility, sleep, and movement are more beneficial for reducing pain and promoting healing.
- Cooling neurons with ice can temporarily shut them down, but they rebound with greater pain when they become active again.
- Therefore, heat is believed to be more effective for wound healing and pain reduction.
- Chronic pain is described as a result of plasticity gone wrong, similar to PTSD for the emotional and stress systems.
Chronic and/or Whole Body Pain; Red-Light Therapy, Sunlight
Chronic and whole-body pain, such as fibromyalgia, is associated with a lack of inhibition in the brain's pain responses. Red light therapy and sunlight are being explored as potential treatments for fibromyalgia. The effectiveness of red light therapy is limited, but systemic therapy, similar to sunlight exposure, may be more beneficial. These therapies are considered surrogate technologies for exposure to red wavelengths in sunlight.
Key points:
- Chronic and whole-body pain is linked to a lack of inhibition in the brain's pain responses.
- Red light therapy is being studied as a potential treatment for fibromyalgia, but its effectiveness is limited.
- Systemic therapy, similar to sunlight exposure, may be more beneficial for pain relief.
- Red light therapy and sunlight are considered surrogate technologies for exposure to red wavelengths in sunlight.
Glymphatics and Sleep
- Glymphatics is a brain system that removes waste and toxins.
- During sleep, glymphatics becomes more active, aiding in waste removal and healing.
- Sunlight and stem cells may have potential benefits in relation to glymphatics and sleep.
Stem Cells, Platelet Rich Plasma (PRP: Shams, Shoulds and Should Nots
The use of stem cells and platelet-rich plasma (PRP) in medical treatments is a topic of discussion. Stem cells have the potential to become any type of cell, but their use in therapy is not yet approved. PRP involves enriching blood with platelets and reinjecting it into the body, but it is unclear whether the injection or the PRP itself is responsible for therapeutic effects. The claim that PRP contains stem cells is weak, as the number of stem cells in PRP is extremely small. Advertising PRP as containing stem cells is illegal. Caution should be exercised when considering PRP therapy, and more research is needed in this evolving field. Stem cell treatments have faced skepticism due to incidents where patients went blind after receiving stem cell injections. The marketing around PRP treatments is questionable, and the benefits reported by some individuals may be due to placebo effects. Stem cells have the potential to become tumor cells, highlighting the need for caution. It is important to be informed about the evidence and scientific research behind these treatments, and further advancements in the field should be awaited before considering stem cell injections.
Young Blood: Actual Science
Young blood, specifically the blood of young rodents and umbilical cords, has rejuvenating effects on older animals, improving memory, vitality, and wound healing. Researchers have identified molecules in young blood, such as TIMP2, that revitalize the brain and body. Blood transfusions from young to old individuals could be a potential treatment. The gut microbiome also plays a role in regulating health and treating conditions like obesity. The science aims to understand the factors in young blood that decline with age. This research holds promise for potential treatments for dementia and other age-related conditions.
