Having a positive attitude seems to boost immunity & even slow aging. But how? New study 🐭 shows neurons in the insular cortex increase the number & activity of immune cells in the gut & around organs. Breakthrough!👇1/6 
150 years ago it was discovered that presenting patients allergic to pollen with an artificial flower is sufficient to induce an allergic response (Mackeszie, 1886) 3/6
Many gut-related disorders are suggested to be psychosomatic, induced by emotionally stressful experiences. This study may explain why 4/6
Researchers @TechnionLive focused on the insular cortex (InsCtx) but this brain region is most likely only a part of immune-related information in the brain, Other brain areas may be even more crucial for this process 5/6
Why does the brain control immunity? Maybe the brain, which constantly records external cues (e.g., place and odor), also records its own response to these experiences “to enable a more effective, anticipatory immune reaction to recurring stimuli.” 6/6
