Study Reveals How Second Brain in Gut Communicates

A particular type of neuron in the gut wall that communicates signals to other neurons outside the gut, near the spinal cord and up to the brain has been discovered by Professor Nick Spencer’s laboratory. The findings of the study are published in the eNeuro journal. You’re faced with a big decision so your second brain provides what’s normally referred to as ‘gut instinct’, but how did this sensation reach you before it was too late?

The Enteric Nervous System (ENS) is a network of neurons and transmitters wrapped in and around the human gut with the prime function of managing digestion, but researchers at Flinders University are delving into the complexity of this brain like system to uncover it’s secret capabilities.

“There is significant interest in how the gut communicates with the brain as a major unresolved issue because of growing evidence that many diseases may first start in the gut and then travel to the brain, an example of which is Parkinson’s Disease,” says Professor Spencer.

“The new study has uncovered how viscerofugal neurons provide a pathway so our gut can “sense” what is going on inside the gut wall, then relay this sensory information more dynamically than was previously assumed to other organs, like the spinal cord and brain which influence our decisions, mood and general wellbeing.”

Professor Spencer says there is increasing interest in understanding how the nervous system in the gut (ENS) communicates with the brain, to give us all those sensations we know of.

“What is particularly exciting about the gut, is that it is unlike all other internal organs (e.g. heart, liver, bladder) because the gut has its own nervous system, which can function independently of the brain or spinal cord. Understanding how the gut communicates and controls other organs in the body can lead to important breakthroughs for disease treatment and this is an important step in the right direction.”
