New imaging technique in Alzheimer’s disease opens up possibilities for new drug development

Tau PET is a new and promising imaging method for Alzheimer’s disease. A case study from Lund University in Sweden now confirms that tau PET images correspond to a higher degree to actual changes in t..

How a fluctuating brain network may make us better thinkers

For the past 100 years, scientists have understood that different areas of the brain serve unique purposes. Only recently have they realized that the organization isn’t static. Rather than having stri..

Zika infects neural cells related to skull formation, affecting their function

Cranial neural crest cells — which give rise to the bones and cartilage of the skull — are vulnerable to Zika virus, report Stanford University School of Medicine researchers September 29 in Cell Host..

Breakthrough in mapping nicotine addiction could help researchers improve treatment

A scientific blueprint to end tobacco cravings may be on the way after researchers crystallized a protein that holds answers to how nicotine addiction occurs in the brain. Researchers at the Peter O’..

How the brain makes new memories while preserving the old

Columbia scientists have developed a new mathematical model that helps to explain how the human brain’s biological complexity allows it to lay down new memories without wiping out old ones — illustrat..

Keeping your synapses sharp: How spermidine reverses age-related memory decline

Synapses, connecting the neurons in our brains, continuously encode new memories, but the ability to form new memories (“learning”) diminishes drastically for many of us as we get older. Electron mic..

Brain diseases manifest in the retina of the eye

Diseases of the central nervous system (CNS) may manifest as pathological changes in the retina of the eye. Research from the University of Eastern Finland (UEF) shows that retinal changes may be dete..

New treatment strategy could cut Parkinson’s disease off at the pass

Researchers at Johns Hopkins report they have identified a protein that enables a toxic natural aggregate to spread from cell to cell in a mammal’s brain — and a way to block that protein’s action. Th..

Game theory research reveals fragility of common resources

New research in game theory shows that people are naturally predisposed to over-use “common-pool resources” such as transportation systems and fisheries even if it risks failure of the system, to the ..

Brain disruptions similar across many emotional disorders

Researchers have long known that emotional disorders have a lot in common. Many often occur together, like depression and social anxiety disorder. Treatments also tend to work across multiple disorder..

Scientists identify neurons devoted to social memory

Mice have brain cells that are dedicated to storing memories of other mice, according to a new study from MIT neuroscientists. These cells, found in a region of the hippocampus known as the ventral CA..

Cocaine accumulation in fish eyes

A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals — espe..

Alcohol shown to act in same way as rapid antidepressants

Can having a few drinks help people with clinical depression feel better? Yes. At least in terms of biochemistry. In a study published in the current issue of the journal Nature Communications, rese..

Rest and well-being: World’s largest survey

Over two thirds (68 per cent) of the public would like more rest, according to the world’s largest ever survey on the topic. The results of the survey, led by Durham University researchers, also rev..
