Cleaning the Brain After Stroke
A research team has shed light on the dynamics of efferocytosis, the elimination of dying cells, following ischemic stroke.
Circuitry That Links Pain to Negative Emotion Identified in Rat Study
A new study has uncovered neuronal circuitry in the brain of rodents that may play an important role in mediating pain-induced anhedonia – a decrease in motivation to perform reward-driven behaviors.
"Mental Shortcuts" Lead to Poorer Decision-Making by Delivery Room Doctors
Algorithms and analytics are now common used by professional sports, in sales forecasts, lending decisions and by car insurance providers. Managers and other decision makers no longer simply “go with their gut.” But, new research suggests, doctors often remain reluctant to introduce such information when making medical decisions for patients.
How Does Our Brain Navigate Cities?
A new MIT study suggests that our brains are actually not optimized to calculate the so-called “shortest path” when navigating on foot. Based on a dataset of more than 14,000 people going about their daily lives, the MIT team found that instead, pedestrians appear to choose paths that seem to point most directly toward their destination, even if those routes end up being longer.
Neuroinflammatory Protein Linked to Worse Glioblastoma Survival in Males
Scientists have discovered a link that could improve understanding of why glioblastoma, the most common malignant brain tumor, is more deadly in males than females.
Largest Ever Analysis of Brain Metabolism Completed in Mice
The first atlas of metabolites in the mouse brain has been published and includes 1,547 different molecules across 10 brain regions in male and female laboratory mice from adolescence to advanced old age.
Time Spent in Outdoor Light Linked to Improved Sleep
A new study has revealed that getting enough natural sunlight each day can impact a person’s mood and sleep quality.
"It's Been My Whole Life for Five Years": Scientists Reveal the Brain's "Fingerprint"
An EPFL scientist has pinpointed the signs of brain activity that make up our brain fingerprint, which – like our regular fingerprint – is unique.
Why Do We Have Better Memories of Stressful Experiences?
Stressful experiences are usually remembered more easily than neutral experiences. Researchers at Ruhr-Universität Bochum (RUB) have analysed this phenomenon, finding that memories of objects from stressful situations seem to rely on similar brain activity as memories of the stress trigger itself.
As Neurodegeneration Begins, the Brain's Immune Cells Are Ravenous for Sugar
At the beginning of neurodegenerative disease, the immune cells of the brain – the “microglia” – take up glucose, a sugar molecule, to a much greater extent than hitherto assumed.
