Estrogens alleviate hyperactivity in zebrafish with autism gene

Research led by UCL, Yale and University of California, San Francisco has shown that the hormone estrogen alleviates the sleep disruption experienced by zebrafish genetically designed to help understand the biology of autism ...

Neuroscience

Fly method is epilepsy's ray of light

Professor Richard Baines and Dr Carlo Giachello used a genetically-altered fruit fly to show that when nervous system activity is suppressed by shining yellow light through its embryo, it will not go on to develop symptoms ...

Neuroscience

Tools for illuminating brain function make their own light

Optogenetics has taken neuroscience by storm in recent years because the technique allows scientists to study the brain conveniently in animals, activating or inhibiting selected groups of neurons at the flip of a switch. ...

Depolarizing wave may trigger sudden death in epilepsy

A slow, depolarizing electrical wave – sometimes called a "brain tsunami" – may be the hidden cause of sudden unexpected death in epilepsy, a disorder that kills as many as 4,000 people in the United States each year, ...

Neuroscience

Understanding how neurons shape memories of smells

In a study that helps to deconstruct how olfaction is encoded in the brain, neuroscientists at University of California, San Diego School of Medicine have identified a type of neuron that appears to help tune, amplify and ...

Neuroscience

'Microlesions' in epilepsy discovered by novel technique

Using an innovative technique combining genetic analysis and mathematical modeling with some basic sleuthing, researchers have identified previously undescribed microlesions in brain tissue from epileptic patients. The millimeter-sized ...

New genetic cause for progressive form of epilepsy identified

An international research consortium has discovered a new gene underlying progressive myoclonus epilepsy, one of the most devastating forms of epilepsy. The study showed that a single mutation in a potassium ion channel gene ...
