Summary: Researchers designed a technology that allows them to probe and control the neural circuits between the gut and brain, demonstrating their ability to influence feelings of fullness or reward-seeking behavior in mice. The interface used flexible fibers embedded with sensors, temperature sensors, and light sources for optogenetic stimulation. The aim is to use this technology to explore the links between digestive health and neurological conditions such as autism and Parkinson’s disease. This work opens up the potential to manage these conditions by manipulating peripheral circuits in a non-invasive way. […]
