Poop for depression

It has long been known that the microbiome has a significant influence on the human brain. Now more tactical observations (1) confirm that certain missing species in the gut could lead the host to depression. This is an important finding that may lower brain research to focus on lower parts of the body. 

The gut has been an unavoidable and most important aspect of large biological systems including humans. There they converted plant and animal matter to energy, powered their ever agreeable computer and went to work. Most systems had very efficient designs of the brain, just capable of keeping their mechanical systems that controlled the body in tune. Then the freak, human, showed up, with significant excess capacity in an organ that tends to get bored. However, the small ones in the gut always held the strings. It is possible that they are using the quantum computer upstairs for research, without the knowledge of the host.

Fecal transplant seems to solve many problems and lately CNS issues, including depression. The predictive power of microbiome on the occurrence and amelioration of human disease states is higher than what can be done with the compendium of medical knowledge based on foreign chemical agents. In fact, chemical agents that destroy the microbiome, albeit being able to show short term benefits, lead to long term deleterious effects on the system. Antibiotics certainly fall into this category. More importantly, these agents seem to have accelerated the decline of beneficial bacteria while simultaneously increasing the potency of the bad ones.

Medicine may need to focus on, not on the host, but what the host carries. The later, perhaps accounting for over half of the live cells in the system, appears to control almost everything including the host's brain.
