7. Gut’s nervous system

8. What is The Brain in the Gut?  The Enteric Nervous System is embedded in the lining of the GI system:  Esophageus  Stomach  Small intestine  colon

9. Brain in the Gut

10. Neurotransmitters: Serotonin  Although manufactured in the brain, 90-95% of our supply is found in the digestive tract  Vital for communication  Important to motility and sensitivity to gut sensations  It is also a “feel good” hormone

11. Can operate independently of the brain and spinal cord

37. Mind Gut Connection  Symptoms themselves can be stressful  AND stress itself can make any symptoms worse

38. Some Current and Recent Explorations  Stay tuned……..

39. Research  In 2014, the US National Institute of Mental Health spent more than $1 million on research aimed at the microbiome connection

43. Autism Research  Our intestines are home to a diverse community of beneficial organisms. This community may be altered in problematic ways in some individuals with autism.

44. Clinical Trial: Prebiotics on Mood Those taking the prebiotic had a reduced tendency to pay attention to negative information, which is a key component of anxiety and depression.  They also had lower levels of stress hormone cortisol, which has also been connected to anxiety and depression.
