Describe how microbial communities in the body could influence brain and mental health states. Then, describe how brain and mental health states could influence microbial communities in the body. In what ways might these promote health and/or disease?
The brain and mental health states could influence microbial communities through the release of neurotransmitters and hormones.
Small molecule byproducts from microbial communities could travel through sympathetic nerves that affect brain function. Microbes also produce corticosteroids and neurotransmitters themselves.
Since gut and brain are connected to each other, this could affect health greatly one way or another. Microbial communities are very sensitive and are known to cause issues if drastically altered. Mental health affects physical health and vice versa.
