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.....
