Insular Cortex Mediates Increased Pain Tolerance in Yoga Practitioners | Cerebral Cortex

Insular Cortex Mediates Increased Pain Tolerance in Yoga Practitioners | Cerebral Cortex | Health, Nutrition, Fitness, & Recreation | Scoop.it

ABSTRACT: Yoga, an increasingly popular discipline among Westerners, is frequently used to improve painful conditions. We investigated possible neuroanatomical underpinnings of the beneficial effects of yoga using sensory testing and magnetic resonance imaging techniques. North American yogis tolerated pain more than twice as long as individually matched controls and had more gray matter (GM) in multiple brain regions. Across subjects, insular GM uniquely correlated with pain tolerance. Insular GM volume in yogis positively correlated with yoga experience, suggesting a causal relationship between yoga and insular size. Yogis also had increased left intrainsular white matter integrity, consistent with a strengthened insular integration of nociceptive input and parasympathetic autonomic regulation. Yogis, as opposed to controls, used cognitive strategies involving parasympathetic activation and interoceptive awareness to tolerate pain, which could have led to use-dependent hypertrophy of insular cortex. Together, these findings suggest that regular and long-term yoga practice improves pain tolerance in typical North Americans by teaching different ways to deal with sensory inputs and the potential emotional reactions attached to those inputs leading to a change in insular brain anatomy and connectivity.

The Vegetarian Cook -- Eco Warrior Princess

The Vegetarian Cook -- Eco Warrior Princess | Health, Nutrition, Fitness, & Recreation | Scoop.it

. So this year I set my mind to cooking dinner at 3-4 times a week. I came to this decision because eating out was not only biting (pun intended) into my disposable income but I thought it would be a good challenge – and much more appetising than running a marathon which I was also seriously considering at the time.
