Astrocytes are notoriously two-faced—calmly coddling neurons one minute, then ruthlessly consuming their synapses the next. Why these dramatic mood swings? Blame the EphA4 receptor, according to a ...

Astrocytes are the major glial cell in the central nervous system. These polarized cells elaborate numerous processes that ensheath the vasculature and contact synapses. Astrocytes play important ...

The functioning of the brain relies on the establishment of very precise connections between neurons: synapses. A recent ...

Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the synapse—the site at which signals are passed between the brain cells. The nervous system ...
