Study traces brain-to-gut connections - insula stress ulcers - But ANS "fight or flight" response leads to primary motor cortex.

Neuroscientists at the University of Pittsburgh Brain Institute have traced neural pathways that connect the brain to the stomach, providing a biological mechanism to explain how stress can foster ulcer development.

The findings, published this week in the Proceedings of the National Academy of Sciences, build a scientific basis for the brain’s influence over organ function and emphasize the importance of the brain-body connection....

In contrast, the sympathetic — “fight or flight” — pathways of the central nervous system, which kick in when we’re stressed, predominantly trace back from the stomach to the primary motor cortex, which is the seat of voluntary control over the skeletal muscles that move the body around.

You could make the case using these studies that Sars-cov-2-wuhan enters the human system via the ACE2 enzyme pathway and in that process creates stress. This stress level is beyond some people's (with comorbidities) immune system abilities to handle it, which leads to pneumonia or ARDS and ultimately organ failure of one type or another.

There is a connection between the gut and brain. We have heard of the gut being called, "the second" brain. A good quality probiotic is important. We take on with soil microrganisms.
