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 ...

Inhibiting epileptic activity in the brain

Epileptic seizures often originate in small, localized areas of the brain where neurons abnormally fire in unison. These electrical impulses disrupt proper brain functioning and cause seizures. But what makes regions where ...

Two molecular handshakes for hearing

We hear sounds in part because tiny filaments inside our inner ears help convert voices, music and noises into electrical signals that are sent to our brains for processing. Now, scientists have mapped and simulated those ...

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 ...

Neuroscience

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.

Harnessing the body's ability to heal

Researchers at Mayo Clinic are studying ways to engineer human-like tissue to bolster the body's ability to heal itself. Scientists in the Regenerative Medicine Biomaterials and Biomolecules Lab have engineered biomaterials ...
