Our Second Brain


Did you know you have 2 brains? “The Enteric Nervous System (ENS or gut) is analogous to a microcomputer with its own independent software, whereas the brain is like a larger mainframe.”


Your gut brain doesn't share its supply of serotonin with your cranial brain, but it does influence the cranial brain by stimulating the vagus nerve. This nerve descends from cranial brainstem through the neck to the abdomen, allowing for two-way talk between the gut & cranial brains.The gut is the chatty one, sending up 9 nerve impulses for every 1 it receives in return. Even with all this checking in, the enteric nervous system in the gut can operate largely independently of the cranial…


The intestines have their own nervous system, the ENS (enteric nervous system), which has over 500 million neurons. Scientists are investigating how ENS nerve cells communicate with brain neurons through the ‘gut-brain axis’. The latest research shows the actions of ENS neurons are affected by events in the gut environment, including the activities of bacteria …


Understanding the relationship between your mind health & your gut. (Just been reading about new scientific trials in this area - watch this space?!!)


Human Beings have an Autonomic Nervous System (ANS) that is actually comprised of three separate subsystems, the Parasympathetic Nervous System (PNS), the Sympathetic Nervous System (SNS) and the Enteric Nervous System (ENS). The enteric nervous system has been described as a "second brain," which communicates with the central nervous system (CNS) through the parasympathetic (e.g., …


Can Our Guts Influence Our Mood, & Much More?

Can our guts influence our emotional state? ENT, or as it’s better known as – enteric nervous system, gives some interesting insight.


Technically known as the enteric nervous system, the second brain consists of sheaths of neurons embedded in the walls of the long tube of our gut, or alimentary canal, which measures about nine meters end to end from the esophagus to the anus. The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system, Gershon says.

Researchers identify new genetic variants in Hirschsprung’s disease development.

Genetic studies in humans, zebrafish and mice have revealed how two different types of genetic variations team up to cause a rare condition called Hirschsprung’s disease. The findings from Johns Hopkins University add to an increasingly clear picture of how flaws in early nerve development lead to poor colon function, which must often be surgically corrected. The study also provides a window into normal nerve development and the genes that direct it. The opensource study is published in the…
