Scientists have identified two types of brain cells in the abdomen that appear to control different aspects of digestion.
For example, a team at Caltech has identified two distinct types of neurons in the abdomens of mice that appear to control different aspects of digestion., helps explain how clusters of neurons in the body play a key role in the gut-brain connection, a complex two-way communication system between the brain and digestive system.
"Your adrenaline goes up and your glucose level in the blood is really high because you need to fight or flight," Oka says. The team used cutting-edge genetic techniques to characterize the neurons in that cluster. They found two distinct types of cells, with distinctly different jobs."It turned out that digestive-related function are controlled by one major cell type, and another class of neuron is involved in gut motility," Oka says.
Although the study was limited to signals traveling from the brain to the gut, Duca says, other research suggests that specialized neurons also help send information in the other direction.
