Current stimulation may keep visual neurons alive after injury — but at a cost

Researchers report that for rats and mice, repetitive transorbital alternating current stimulation (rtACS) may help preserve visual neurons from cell death after injury.

New way of preventing pneumococcal brain invasion

An international team of researchers has identified two receptors on the cells in the blood vessels of the brain that can be blocked and thereby prevent pneumococci from entering the brain. The study shows that the use of antibodies that block the rece…

Blind people have brain map for ‘visual’ observations too

Is what you’re looking at an object, a face, or a tree? When processing visual input, our brain uses different areas to recognize faces, body parts, scenes, and objects. Scientists have now shown that people who were born blind use a ‘brain map’ with a…

Computer game could help children choose healthy food

A simple brain-training game could help children choose healthy snacks instead of chocolate and sweets, according to a new study.

Finding traces of memory processing during sleep

Sleep helps us to retain the information that we have learned during the day. We know from animal experiments that new memories are reactivated during sleep. The brain replays previous experience while we sleep – and this replay strengthens memories …

Diverse populations make rational collective decisions

Yes/no binary decisions by individual ants can lead to a rational decision as a collective when the individuals have differing preferences to the subject, according to new research.

Tool may help determine older adults’ history of sports concussions

A new study in retired athletes takes the first steps in developing an objective tool for diagnosing a history of sports concussions.

Scientists uncover a role for the microbiome in regulating fear responses

New research has shown that the microbiome, the collective trillions of bacteria within the gastrointestinal tract, regulates fear responses and modifies the brain function of adult mice.

Basis of ‘leaky’ brain blood vessels in Huntington’s Disease identified

By using induced pluripotent stem cells to create endothelial cells that line blood vessels in the brain for the first time for a neurodegenerative disease, neurobiologists and colleagues have learned why Huntington’s disease patients have defects in…

Sick kids live longer, but brain function may suffer

Hundreds of thousands of children with chronic illnesses who used to die are now surviving their disease and treatment—which is amazing. But their brains are being damaged in the process of keeping them alive. This first ever research quantifies the …
