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 ...

Neuroscience

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 ...

Neuroscience

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 ...

Neuroscience

Dopamine-producing neurons fulfil important function in the brain

Nerve cells that produce dopamine for the purpose of transmitting signals to other cells affect numerous crucial brain functions. This becomes evident in diseases such as Parkinson's and schizophrenia, where dopamine transmission ...

Neuroscience

Why some neurons 'outsource' their cell body

Nerve cells come in very different shapes. Researchers at the Bernstein Center Berlin now reveal why, in insects, the cell body is usually located at the end of a separate extension. Using mathematical models, they show that ...

Study reveals novel role for the Pin1 molecule

Synapses are "dynamic" things: they can regulate their action in neural processes related to learning, for example, but also as a consequence of diseases. A research team – led by SISSA – has demonstrated the role of ...
