A new study on rare ‘split brain’ patients sheds light on feature of human sleep

A new study of researchers at IMT School for Advanced Study Lucca demonstrates for the first time that the slow waves of NREM-sleep travel and propagate in the brain through “anatomical highways”. The scientists have investigated in particular the role of the corpus callosum, the bundle of nervous fibers that connects the two brain emispheres, by enrolling in the research a group of “split brain” patients.
