Video: Enteric nervous system is like 'second brain'
A four-minute video discusses how the enteric nervous system, an extensive mesh-like network of neurons that controls the digestive tract, acts like a 'second brain'. According to scientists, 80-90% of the nerve fibres that transmit signals, are from enteric nervous system to the brain. Therefore, the video states that the system, like the brain, can initiate its own reflexes.
