Astrocytes Couple Synaptic Activity to Glucose Utilization in the Brain

Abstract

Astrocytes have functional characteristics that make them particularly well suited to couple glutamate uptake from the synaptic cleft to Na(+)-K(+)-ATPase activation and glucose utilization. The changes in glucose metabolism associated with these processes may provide signals detected by positron emission tomography.
