Firing of neurons changes the cells that insulate them

Through their pattern of firing, neurons influence the behavior of the cells that upon maturation will provide insulation of neuronal axons, according to a new study publishing 22 August in the open access journal PLOS Biology ...

Blame it on the astrocytes

In the brains of all vertebrates, information is transmitted through synapses, a mechanism that allows an electric or chemical signal to be passed from one brain cell to another. Chemical synapses, which are the most abundant ...

Researchers identify how cells control calcium influx

(Medical Xpress)—When brain cells are overwhelmed by an influx of too many calcium molecules, they shut down the channels through which these molecules enter the cells. Until now, the "stop" signal mechanism that cells ...
