Astrocytes emerge as the unexpected conductors of brain networks

by University of Lausanne edited by Stephanie Baum, reviewed by Robert Egan  Editors’ notes Astrocytes are found throughout the brain. Each astrocyte is in contact with several neurons and more than 100,000 synapses. A new study shows that at the microscopic level, dozens of synapses from distinct neural circuits gather around a single specialized astrocyte structure called a
