They tracked how connectivity between brain networks changed over time and grouped it into six recurring states.","gist":"Using resting-state fMRI in 50 patients with idiopathic generalised epilepsy and 50 matched controls, the study found altered dynamic connectivity between brain networks, linked to disease duration and seizure frequency.","meaning":"The claim concerns how the brain moves between recurring patterns of network connectivity, not just how strongly networks connect on average. It reports that patients differed from controls in how often they switched states, how long they stayed in a state, and how much time they spent in particular states.
