An astrocyte bridge from synapse to blood flow
@article{Parri2003AnAB, title={An astrocyte bridge from synapse to blood flow}, author={Rheinallt Parri and V. Crunelli}, journal={Nature Neuroscience}, year={2003}, volume={6}, pages={5-6} }
Neural activity locally increases cerebral blood flow to deliver oxygen to working neurons. A new paper shows that astrocytes can detect activity at glutamatergic synapses via calcium changes in astrocytic endfeet and directly couple it to blood flow in vitro and in vivo.
