Research sheds new light on how brain stem cells are activated

Scientists have found that neural stem cells use molecules that form a complex called STRIPAK to ‘wake up’ and produce new neurons (nerve cells) and surrounding glial cells in the brain.

Ultrasound method restores dopaminergic pathway in brain at Parkinson’s early stages

Researchers have developed a technique that could open up new ways to facilitate targeted drug delivery into the brain, enabling drugs to treat brain diseases more focally. They used transcranial, focused ultrasound and intravenously injected microbubb…

Voluntary exercise prompted the brain to prune surplus connections between nerve cells and reduced behavioral symptoms of ASD in a mouse model.

Brain disorder leaves lasting legacy of disability

Four out of five people with a hidden brain condition that causes limb weakness or paralysis experience lasting physical difficulties.

Improved human brain organoids to boost neurological disease research

Research has optimized the process of making human brain ‘organoids’ — miniature 3D organ models — so they consistently follow growth patterns observed in the developing human brain. Researchers can use this reproducible experimental system to test d…

Was Mona Lisa’s smile a lie?

Using chimeric — or mirror — images, researchers have determined that one half of Mona Lisa’s smile displays happiness while the other half is neutral reflecting a non-genuine emotion.
