Research output: Contribution to journalComment/debate

Abstract

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.
