Nerve cells let others 'listen in'

How many 'listeners' a nerve cell has in the brain is strictly regulated. This is shown by an international study led by the University College London and the universities of Bonn, Bordeaux and Milton Keynes (England). In ...

Thicker nerve fibers enable faster reactions in mice

In order for organisms to react swiftly to stimuli in their environment, they need rapid and precise transmission of nerve impulses along neural extensions known as axons. Whereas some invertebrates have developed very thick ...

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 ...
