Document Summary

Finishing off the last bit of gut-brain communication. We have a nervous system controlling our body but then we have billions of single cell organisms living largely in our gut and: Our brain is influencing their activity through cortisol release or immune system involvement. They can actually also influence us and our behavior by affecting the brain through their release of neurotransmitters that can get into to the bloodstream from the gut and get up into the brain. This can affect the neural circuits in the brain to affect neural mood and cognition. Show a difference between how animals behave depending on their possession of microbiota. Thus by investigating the different behaviors we can attribute them to the presence or absence of microbiota. Animals get colonized by microbiota when they are born and their mother"s microbiota will have infected them through the mother"s birth canal.
