Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct ‘fight or flight’ and ‘rest and digest’ circuits. These results explain how mental states can affect the gut, and present new ways to treat gastrointestinal problems.
The process of how both error and reward signals are organized within the cerebral cortex are revealed by researchers.
Scientists discover fundamental connectivity pattern in the brain. Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed.
