It is not necessarily that reduced brain activity is linked to poorer task completion: imaging technique, xenon 133 is inhaled during the study: Brain regions that are more active will be marked by more xenon 133 uptake: cognitive deficits in sz, time-course of deficits, subtle deficits appear early in childhood: Deficits are visible at first diagnosis (e. g. , home movie coding of sz patients as children found subtle evidences of cognitive change):
