title: Feeding hungry neurons: astrocytes deliver food for thought.
abstract: Among the proposed roles for astrocytes in the CNS is nutritive support for neurons. In this issue of Neuron, Voutsinos-Porche et al. provide evidence that astrocyte uptake of synaptic glutamate triggers astrocytic glycolysis and release of lactate, which in turn nourishes neurons and sustains neuronal activity.
