Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries

Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries

Seven days after mTBI, the blood vessels (stained in red) in the tissues around the brain are not completely repaired. A marker for intact vessels was used (labeled in green) to distinguish fully functional blood vessels (yellow) from ones that are still damaged (red).

Learning skills of mice help researchers pinpoint brain areas where acquired knowledge is stored

Learning skills of mice help researchers pinpoint brain areas where acquired knowledge is stored

Mice can become experts in sorting images by subtle differences. Part of the acquired knowledge is stored in early visual areas of the brain. Credit: MPI of Neurobiology/ Kuhl Is it a Rembrandt or a Vermeer? For lay people, it is often challenging to distinguish paintings by these two old masters. For the trained eye …

Researchers study recurrent neural network structure in the brain

Yihan Wang (left), a Ph.D. student in the University of Wyoming’s Doctoral Neuroscience Program, and Qian-Quan Sun, a UW professor of zoology and physiology, examine a mouse brain image captured with the UW Microscopy Core’s new slide scanner. The two scientists learned that a recurrent neural network structure, or RNN, is responsible for decision-making, expressive …

Time until dementia symptoms appear can be estimated via brain scan

Time until dementia symptoms appear can be estimated via brain scan

Credit: Pixabay/CC0 Public Domain Researchers at Washington University School of Medicine in St. Louis have developed an approach to estimating when a person who is likely to develop Alzheimer’s disease, but has no cognitive symptoms, will start showing signs of Alzheimer’s dementia. The algorithm, available online in the journal Neurology, uses data from a kind …

Your brain learns to steer your attention away from disturbing sounds

Your brain learns to steer your attention away from disturbing sounds

With the help of EEG, Maja Dyhre Foldal can register electric activity in the brain. The participants in her experiments solve tasks while listening to a rhythm and unexpected sounds. Credit: Annika Thomson. Most people who have been students can recognize this: You have managed to put down your phone with all its visual and …

New research project aims to better understand the brain basis of cognitive control

Are you able to start a task and stick with it, all the way through, ignoring the temptations of the internet or the sudden realization that you should probably do the laundry? Or maybe you should be doing something else right this moment? The faculty that allows people to make plans or goals, and carry …

Measurement of brain function shows benefits of virtual reality in creative arts therapies

Measurement of brain function shows benefits of virtual reality in creative arts therapies

Virtual reality (VR) continues to expand its uses in medicine, specifically in treatments for psychological conditions like trauma, phobias and eating disorders. The technology is also emerging as a tool in creative arts therapies. In one of the first studies of its kind, researchers from Drexel University’s College of Nursing and Health Professions and School …
