Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike ...

A new study challenges the long-held belief that axons, brain cell extensions, are tube-like, revealing instead a "pearl-on-a ...

Biology textbooks may need a revision, say scientists, who present new evidence that an arm-like structure of mammalian brain cells may be a different shape than scientists have assumed for more than ...

A provocative study is claiming that biology textbooks are going to need some major revisions – although not everyone is ...

“Understanding the structure of axons is important for understanding brain cell signaling,” says Shigeki Watanabe, Ph.D., ...

Communication in these cells is long distance, explained Goldstein. “If you imagine the cell body as a 50-foot room, the axon could extend up to 200 miles away,” he said. “The cell would have to ship ...

Consider a neuron, or nerve cell. Each neuron has an axon, a cable-like appendage that transmits electrical signals to nearby neurons. Those electrical signals help your brain perceive your ...

They discovered in human stem cell models of MND, the axon - the long part of the motor neuron cell that connects to the muscle - was shorter than in healthy cells. And the movement of the ...

A long fibre (axon) which is insulated by a fatty (myelin ... These receive incoming impulses from other neurones. Receptor cells detect a change in the environment (a stimulus) and start ...

This review considers the role that optic nerve head astrocytes might play in the initiation of axon damage, based on the hypothesis that these cells are sensitive to mechanical or ischaemic ...
