The reason some people fail to recover their sense of smell after COVID-19 is linked to an ongoing immune assault on olfactory nerve cells and an associated decline in the number of those cells, a team of scientists led by... Continue Reading →
Today, by and large, patients receive a diagnosis of Alzheimer's only after they exhibit well-known signs of the disease, such as memory loss. By that point, the best treatment options simply slow further progression of symptoms. But research has shown... Continue Reading →
One in five people who survive cardiopulmonary resuscitation (CPR) after cardiac arrest may describe lucid experiences of death that occurred while they were seemingly unconscious and on the brink of death, a new study shows. Led by researchers at NYU... Continue Reading →
Researchers at The University of Queensland have discovered a link between obstructive sleep apnoea and an increased risk of developing dementia. Professor Elizabeth Coulson from UQ’s Queensland Brain Institute and School of Biomedical Sciences and her team found a causal relationship between a lack... Continue Reading →
Griffith University researchers have demonstrated that a bacteria can travel through the olfactory nerve in the nose and into the brain in mice, where it creates markers that are a tell-tale sign of Alzheimer’s disease. The study, published in the... Continue Reading →
Moving an arm or leg in a rhythmic motion—cranking a handle, for instance, or pedaling a bicycle—is a feat of biological orchestration, as illustrated here in scientific data from a new study of movements made by animals. Muscle force (top... Continue Reading →
A discovery about how some visually impaired adults could start to see offers a new vision of the brain’s possibilities. The finding that the adult brain has the potential to partially recover from inherited blindness comes from a collaboration between... Continue Reading →
The human eye can physically perceive millions of colours. But we don’t all recognise these colours in the same way. Some people can’t see differences in colours – so called colour blindness – due to a defect or absence of the cells in... Continue Reading →
You may not realize it, but each time you recall a memory—like your first time riding a bike or walking into your high school prom—your brain changes the memory ever so slightly. It’s almost like adding an Instagram filter, with... Continue Reading →
