New research sheds light on how ultrasound could be used to treat psychiatric disorders

A new study has shown how the brain gives credit to events, along with how transcranial ultrasound (TUS) can disrupt this process. While currently developed in an animal model, this line of research and the use of TUS could one day be applied to clinic…

Limited brain capacity in humans and birds

Birds and humans have very different networks of neurons in their brains. Nevertheless, their working memory is limited by similar mechanisms.

Mind-controlled robots now one step closer

Researchers teamed up to develop a machine-learning program that can be connected to a human brain and used to command a robot. The program adjusts the robot’s movements based on electrical signals from the brain. The hope is that with this invention, …

Greater exposure to nitrogen dioxide linked to higher levels of biomarkers of Alzheimer’s disease in the brain

A study has found an association between air pollution and higher levels of deposition of beta-amyloid protein in the brain and of neurofilament light (NfL) in cerebrospinal fluid.

Realistic model of mouse hippocampus uncovers new mechanism for pattern separation

Our brains can distinguish highly similar patterns, thanks to a process called pattern separation. How exactly our brains separate patterns is, however, not full,y understood yet. Using a full-scale computer model of the dentate gyrus, a brain region i…

Parkinson’s disease mutation misdirects iron in the brain

A common gene mutation for Parkinson’s disease drives mislocalization of iron in activated microglia, according to a new study. The results may help explain the accumulation of toxic iron in affected brain areas in the disease and provide a basis for t…

Brain study on how to slow down climate change

When it comes to climate-friendly behavior, there is often a gap between what we want and what we actually do. Although most people want to see climate change slowed down, many do not behave in an appropriately sustainable way. Researchers have now use…

SARS-CoV-2 protein interacts with Parkinson’s protein, promotes amyloid formation, study finds

Researchers have shown that, at least in the test tube, the SARS-CoV-2 N-protein interacts with a neuronal protein called alpha-synuclein and speeds the formation of amyloid fibrils, pathological protein bundles that have been implicated in Parkinson’s…

When the brain switches from hearing to listening

What happens in the brain when simply hearing becomes listening? To answer this question, researchers have traced the neuronal fingerprint of the two types of sound processing in the mouse brain.

Learning and protecting itself: How the brain adapts

If there is an injury to the central nervous system such as after a stroke, the brain needs to compensate for this by reorganising itself. To do this, a dense network of molecules between the nerve cells — known as the extracellular matrix — must loo…
