Astrocytes identified as master 'conductors' of the brain
In the orchestra of the brain, the firing of each neuron is controlled by two notes—excitatory and inhibitory—that come from two distinct forms of a cellular structure called synapses. Synapses are essentially the connections ...

Researchers find the adhesions that build the brain's networks
The brain's neurons tend to get most of the scientific attention, but a set of cells around them called astrocytes—literally, star-shaped cells—are increasingly being viewed as crucial players in guiding a brain to become ...
