Psychobiome

Could this affect how people think and feel? Evidence is mounting for a link between the gut and the brain in what is termed the psychobiome—part of the microbiome—that does just that. The substances that the various bacteria, viruses and fungi produce may go directly into the bloodstream and infiltrate blood vessels, or they may stimulate the vagus nerve that connects the gut and the brain.

The psychobiomes that exert a clinical effect through endocrine agents associated with the control of neuroinflammation and the generation of neurotransmitter precursors are identified by the correlations between modified gut microorganisms and MDD [21,22].
