title: Transports of delight.
abstract: Intrinsic optical signals, evoked by neural activity, provide an essentially noninvasive means of monitoring the organization of brain circuitry. A new study by Gurden et al. in this issue of Neuron reveals a surprising role of astrocyte glutamate transporters in generating these signals.
