Brain Cells That Drive Anxiety in Mice Reveal Targets
What the new mouse study shows In a recent line of experiments with mice, researchers mapped specific brain cells that either amplify or suppress anxiety-like behaviors. By observing how these neurons activate during stressful situations, and how their activity shifts when anxiety is reduced, scientists are painting a more nuanced picture of the brain’s emotional…

Post-COVID Olfactory Dysfunction Linked to Amygdala Changes
Understanding the link between persistent smell loss and brain changes after COVID-19 Researchers have identified measurable changes in brain regions tied to emotion and sensory processing in people who continue to experience a loss or distortion of smell long after a SARS-CoV-2 infection. The study, published in Scientific Reports, used advanced MRI techniques to investigate…

Post-COVID Olfactory Dysfunction: Brain Changes Revealed
New insights into long COVID: brain changes linked to persistent smell loss Researchers have found measurable differences in brain regions tied to emotion and sensory processing in people who continue to experience olfactory dysfunction (OD) long after a mild COVID-19 infection. The study, published in Scientific Reports, used diffusion tensor imaging (DTI) to explore white…

Brain Changes in Post-COVID Olfactory Dysfunction Linked to Emotion and Sensory Regions
New clues from MRI on lingering smell loss after COVID-19 Researchers have used diffusion tensor imaging (DTI) to explore how the brain’s smell-related circuits change in people who continue to struggle with olfactory dysfunction (OD) months after a mild COVID-19 infection. The study, published in Scientific Reports, focused on non-hospitalized individuals to minimize confounding factors…

Not Honey and Ginger: A Quirky Way to Prevent Colds, Says Study
A quirky twist on cold prevention As autumn arrives, many of us default to familiar remedies—honey, ginger tea, Vitamin C—when we sense a chilly season ahead. But a recent study from the University of Hamburg suggests that our bodies may be primed to fight colds in a much less traditional way: by watching videos of…
