STAR PLAYERS

Astrocytes (purple) and neurons (green) in the visual cortex of a ferret. The cells contain dyes that allow researchers to track calcium levels. When neurons are active, astrocytes respond with increased calcium, which leads nearby capillaries to increase blood flow. This is a previously undiscovered role for astrocytes, once thought to only act as support cells for neurons.
