Using microelectrodes, scientists could show that cells in the retina play different roles. The produce different signals, which is important for the processing of visual information. These ...

Doctors usually focus on a person's average blood pressure, but research increasingly shows that how much blood pressure ...

The wiring of one insect’s brain no longer contains much uncharted territory. All of the nerve cells — and virtually every connection between them — in a larval fruit fly brain have now been mapped, ...

Human brains (and the brains of other vertebrates) are able to process information faster because of myelin, a fatty substance that forms a protective sheath over the axons of our nerve cells and ...
