Astrocytes help sustain brain activity and blood flow during prolonged sensory stimulation
What happens in the brain when sensory stimulation continues over time—for example, while jogging, reading or listening to music? Sensory input activates specific groups of neurons, increasing their demand for oxygen and nutrients. In response, nearby blood vessels dilate and increase blood flow, a
