TL;DR: Proficient performance in verbal fluency seems to require less metabolic activation than poor performance, perhaps because of the efficiency of cognitive strategies employed.

TL;DR: In this study almost 80% of the variance in CMRglu could not be explained by any of the factors that had been considered, which implies a lack of sensitivity of absolute values of global C MRglu to the mild effects of brain dysfunction.

TL;DR: For patients with Alzheimer's disease, the degree of asymmetry was not related to either the severity or duration of dementia, and could be explained by greater susceptibility of the left hemisphere to degenerative or ischemic brain disease, or most likely, by greater metabolic deficits resulting from left rather than right hemisphere impairment.

TL;DR: It is demonstrated that individuals who suffered from familial developmental dyslexia as children, activate different brain regions during reading as adults, as compared to individuals without such childhood history.

TL;DR: PET studies of brain metabolism, which are designed to study the active brain, should indeed be performed in functionally activated states, as in addition to demonstrating metabolism during a defined functional state, activation studies show reduced variability of cerebral metabolic measures.
