Testing the fluorescent proteins that light up the brain

Neurons are cells in your brain. Shaped like little stars, they flicker and fire off signals to each other. The signals travel up and down the long tendrils, called dendrites, extending out from each point of a neuron's star-shaped ...

New mechanism affecting nerve impulses discovered

Researchers at Linköping University, Sweden, have discovered a new mechanism by which substances can open a certain type of ion channel and thereby regulate nerve impulses. The study, published in the scientific journal ...

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 ...

Repulsion mechanism between neurons governs fly brain structure

The brain's structure has columnar features, which are hypothesized to arise from nerve cells (neurons) stemming from the same parent cell, initially forming radial units. How exactly this process unfolds at the molecular ...

Scientist unveils a 3-D printed device to excite nerves

A tiny, thin-film electrode with a 3-D-printed housing has been implanted in the peripheral nervous system of songbirds, where it successfully recorded electrical impulses that drive vocalizations.

Using light instead of electricity in cochlear implants

A team of researchers affiliated with multiple institutions in Germany has developed a cochlear implant that converts sound waves to light signals instead of electrical signals. In their paper published in the journal Science ...
