While connectome research in epilepsy has moved forward in recent years, there is still a lot we do not know about its role in the disorder. They used this data to map grey matter atrophy, a characteristic of epilepsy, in the patients. They then collected data from another database called the Human Connectome Project, which provides connectome data from a large group of healthy controls. Their hypothesis was that grey matter atrophy would appear most often in parts of the brain where connectivity was highest, known as hubs. The NeuroThe Neuro – The Montreal Neurological Institute-Hospital – is a world-leading destination for brain research and advanced patient care.
