The Gut -- Our Second Brain Notes

  • 1 min - talking belly buttons 2:20
  • 5:26 Michel Neunlist - Nantes, FR - interic nervous system
  • 5:45 reverse evolution sequence
  • Mechanisms 8:30 nurotransmitters, vagus nerve - gut produces 95% of serotonin
  • IBS - Bruno Bonaz, Grenoble - connection between mental health and gut
  • Belly heads 19:00
  • Parkinson's diagnosis possible using gut biopsy. suggests connection of some kind.
  • Gut bacteria might be relevant to other conditions: Alzheimers
  • Abdominal acpuncture -- Dr. Bo, fmri suggest neural effects from treatment. 24:00
  • More philosophical claims: we are passengers in a bacterial bus. (Connect with Sonnenbergs comments on symbiosis.)
  • M may account for 20-30% of calorie intake.
  • Germ sequence - 34mins - We are colonized at birth by bacteria.
  • Dusko Ehrlich - 36 min - very enthusiastic researacher. Looking a M genome.
  • Germ free mice are big risk takers. Bacteria might inhibit risk in host organism. Symbiosis.
  • Example of Toxoplasmosis - bacteria in mice, changes host behavior to be less afraid of cats, Toxo loves cats.
  • Segment on anti-/pro biotics -- some doubts / limits of knowledge.
  • But, interesting stress reponse study by Dr. Kristen Tilllich, UCLA, study using yogurt and strees response to faces while in fMRI
  • More philosophical spin -- The "intelligence" of the bacteria is a 3rd brain.
  • elongated body sequence.....
