Diabetes linked to functional and structural brain changes through MRI

A new study finds that the longer a person has type 2 diabetes, the more likely they may be to experience changes in brain structure. MRI results, researchers say, indicate the negative effects longstanding diabetes may have on brain health outcomes an…

A therapeutic target for Alzheimer’s disease discovered

Scientists have succeeded in reversing certain cognitive manifestations associated with Alzheimer’s disease in an animal model of the disease.

A new mechanism encouraging the brain to self-repair after an ischemic stroke

Partial recovery after ischemic stroke is possible, but the mechanisms involved in this process remain unclear. Researchers identified a whole new pathway promoting brain repair. They discovered lipids secreted from neurons surrounding the area of cell…

Stem cell therapy rescues symptoms of Alzheimer’s disease

Promising preclinical results show hematopoietic stem cell therapy was effective in rescuing memory loss, neuroinflammation and beta amyloid build-up in a mouse model of Alzheimer’s disease.

Research hints at links between babies’ microbiome and brain development

In a small, exploratory study, levels of certain types of microbes in babies’ guts were shown to be associated with performance in tests of early cognitive development.

Brain mechanism that drives focus despite distractions

Neuroscientists find that key neurons in the front of the brain act as ‘traffic control’ to manage our attention to visual stimuli, and help us focus despite distractions.

How psychedelic drugs affect a rat’s brain

Researchers have developed a technique for simultaneously measuring electrical signals from 128 areas of the brain in awake rats. They have then used the information to measure what happens to the neurons when the rats are given psychedelic drugs. The …

A new ally in fighting brain diseases: Our very own skull

Alzheimer’s, stroke, multiple sclerosis and other neurological diseases cause severe damage due to neuroinflammation mediated by immune cells. Managing this inflammation poses a significant medical challenge because the brain is protected by the skull …

Brain cells of males and females respond differently to chronic stress

Researchers have discovered that a subcategory of brain cells responds to stress in a totally different manner in males and females. The findings could lead to a better understanding of health conditions affected by chronic stress, such as anxiety, dep…

‘Ebb and flow’ brain mechanism that drives learning identified

Researchers have long thought that rewards like food or money encourage learning in the brain by causing the release of the ‘feel-good’ hormone dopamine, known to reinforce storage of new information. Now, a new study in rodents describes how learning …
