Neuroplasticity and Pain: Harnessing the Brain's Healing Power
TLDR This episode explores the fascinating world of neuroplasticity and its potential to alleviate pain and promote wound healing. Topics include the brain's ability to dissociate pain from tissue damage, the role of romantic connections in pain relief, the use of mirrors to alleviate phantom limb pain, and the activation of the brain's glimphatic system through sleep and exercise.
Timestamped Summary
00:00
This episode of the Huberman Lab Podcast discusses neuroplasticity and how it can be used to remove pain and promote wound healing.
06:12
The somatosensory system consists of sensors in our skin and deeper layers that send electrical signals to the brain, which then interprets and makes sense of the information, including pain, which is a subjective experience that can be dissociated from tissue damage and can be influenced by factors such as perception and belief.
12:46
The specific type of connection one has to a romantic partner can alleviate physical pain, and there are genetic variations that can make individuals either insensitive or overly sensitive to pain.
18:54
Phantom limb pain can be alleviated by using mirrors to create visual imagery that remaps the representation of the missing limb, demonstrating the brain's ability to control perceptions of the body and potentially providing relief from both physical and emotional pain.
25:15
Restricting the use of the uninjured limb and promoting activity in the injured limb can lead to faster recovery and plasticity in both sides of the brain, according to studies on motor injury.
31:26
Restricting activity in the healthy limb and overworking the injured limb can promote recovery and plasticity in the brain, similar to ocular dominance plasticity, and can be done for one to two hours a day.
37:39
The brain has a lymphatic system called the glimphatic system that clears out debris and promotes repair, which is most active during slow wave sleep, and can be further activated by sleeping on one side or with feet slightly elevated, as well as by engaging in low-level cardio exercise for 30 to 45 minutes, three times a week.
43:54
The brain's glimphatic system, which is most active during slow wave sleep, can be further activated by low-level cardio exercise and is related to a molecule called aquaporin four, which is expressed by glial cells called astrocytes that bridge the connection between neurons, synapses, and the blood and glimphatic systems.
50:14
Infatuation and obsessive love can blunt the pain response and increase one's threshold for pain, likely due to the release of dopamine, which is distinct from the chemicals associated with stable, long-lasting relationships such as serotonin and oxytocin.
56:25
Acupuncture stimulates specific locations on the body, which can modulate pain and inflammation by activating different neural pathways and nerve systems, such as the chronic spinal sympathetic axis and the vagus nerve.
01:02:58
Depending on the intensity and location of acupuncture stimulation, different effects can be achieved, with some stimulating the release of norepinephrine and dopamine to reduce inflammation and pain, while others can trigger anxiety pathways and exacerbate pain.
01:09:08
Stress and the release of adrenaline can counter infection and inflammation, but it's important to regulate the duration of the stress response to prevent negative effects on the immune system.
01:15:34
Heat is more beneficial for wound healing and reducing pain than cold or ice, and chronic pain involves rewiring both the brain and peripheral centers associated with pain.
01:21:44
The use of ice and anti-inflammatory drugs may not be as effective for wound healing and pain relief as previously thought, and other methods such as improving perfusion through the site, deep sleep, low-level cardio, and red light therapy may be more beneficial.
01:27:59
The blood of young individuals has shown potential in improving memory, vitality, and wound healing in older individuals, leading to ongoing research in identifying the specific factors responsible for these effects.
