Researchers define function of an enigmatic synaptic protein

In the brains, neurons communicate by sending chemical signals across synapses. The molecular machinery required to send a signal involves not only the neurotransmitter signal itself, but a large variety of other proteins ...

Use it or lose it

An Ludwig Maximilian University of Munich study reveals that sound-evoked activity of neurons in the auditory system of the mouse increases the thickness of their myelin sheaths - and enhances the speed of signal transmission ...

Why does an anesthetic make us lose consciousness?

To date, researchers assumed that anesthetics interrupt signal transmission between different areas of the brain and that is why we lose consciousness. Neuroscientists at Goethe University Frankfurt and the Max Planck Institute ...

Brain more robust than previously thought

The brain is well capable of coping with the erratic way individual brain cells transmit information. This robustness is quite useful because variation in signal transmission doesn't merely concern noise, but also contains ...

Myelin cells swing along blood vessels to traverse the brain

The cells that create myelin, a fatty material that insulates nerve fibers in the brain's white matter, migrate into the developing brain by climbing and swinging on blood vessels, according to new research led by UC San ...
