Astrocytes (IMAGE) University of Gothenburg Caption The picture shows astrocytes in red and green, the areas where individual astrocytes interconnect are yellow. A single human astrocyte can access as many as millions of neuronal synapses. Astrocytes emerge as a treatment target in stroke, neurotrauma or neurodegenerative diseases. The brain is largely divided between domains of astrocytes, cells profoundly affecting regeneration and functional recovery after stroke or neurotrauma.
