and we are exposed to more chemicals and drugs than any people who ever lived. We are beginning to learn how these changes, along with chronic life stress, can affect not only the gut microbes, but also their complex dialogue and connection with the gut and the brain. These conversations ...
How Your Gut Controls Your BrainMore and more, researchers are finding that the health of bodily microbe populations could be deeply connected to conditions like depression, anxiety, and even autism.
The notion of thegut being connected to the brainis not new. Michael Gershon, MD, wrote an iconic book about the subject back in 1999 calledThe Second Brain (Harper Perennial),in which he pointed out that 90% of your serotonin, the “feel good” neurotransmitter, actually comes from the ...
TheGut-Brain Axis(GBA) is a term that describes how the brain and stomach are connected to one another. The gastrointestinal tract is home to over 100 million neurons1, which are more than in either your spinal cord or your peripheral nervous system. This allows for communication between the...
I. Gut microorganisms can communicate with the brain by sending signals to it. If gut microorganisms respond negatively, these gut-brain interactions sometimes result in such problems as memory loss and depression. 2. Using "good" microorganisms to replace "bad" ones and new medicines that could...
for what causes leptin resistance in the brain when we eat fatty foods. Using cultured brain slices in petri dishes we screened blood circulating factors for their ability to stop leptin actions. After several years of efforts, we discovered a connection between the gut hormone GIP and leptin."...
when our bodies are dehydrated, which triggers the feeling of thirst. But because of thetime delaybetween when we feel quenched and when the body is fully rehydrated, the gut must sense osmolality changes before they happen in the bloodstream, and it must send this information to the brain....
If you often feel unsatisfied, hungry, or down, the problem might be low serotonin production in your gut. The vagus nerve connects the nerves in the digestive system to different areas of the brain. Neurotransmitters are the chemicals that create signals for neural communication. ...
