Cell-type specific astrocyte activation is driven by cortical top-down modulation

The paper investigates how astrocytes respond to bottom-up and top-down neuronal activity in the olfactory bulb, finding that top-down input from the anterior piriform cortex drives astrocytic Ca²+ signaling through sustained GC firing.
