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 ...

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

Newly understood circuits add finesse to nerve signals

(Medical Xpress)—An unusual kind of circuit fine-tunes the brain's control over movement and incoming sensory information, and without relying on conventional nerve pathways, according to a study published this week in ...

Study reveals probable role of Parkinson's protein in healthy brain

(Medical Xpress)—Researchers at the Stanford University School of Medicine have exposed the possible function, in the healthy brain, of a mysterious molecule that has been strongly implicated in Parkinson's disease, a degenerative ...

Genetics

Study identifies new gene variations associated with heart rate

Through a collaborative genome-wide study on individuals, researchers have discovered 14 new genetic variations that are associated with heart rate. Since heart rate is a marker of cardiovascular health, these findings could ...

Neuroscience

Learning requires rhythmical activity of neurons

The hippocampus represents an important brain structure for learning. Scientists at the Max Planck Institute of Psychiatry in Munich discovered how it filters electrical neuronal signals through an input and output control, ...
