Medical Xpress / Brain stores relapse and recovery memories side by side, alcohol study suggests
Every experience leaves a trace in the brain, a memory that can shape future behavior. Alcohol and other addictive substances are no exception. Over time, repeated alcohol use can create strong memories that link certain ...
Medical Xpress / Childhood trauma tied to tough depression cases
People who have experienced adverse childhood experiences are at increased risk of developing depression later in life that is difficult to treat. This is shown in a new twin study from Karolinska Institutet based on Swedish ...
Medical Xpress / High-resolution brain atlas expands with 18 tasks across 11 repeatedly scanned volunteers
The Individual Brain Charting (IBC) project has released its fifth and largest update of high-resolution fMRI data, adding a new set of cognitive tasks to one of the most detailed brain-mapping datasets available today. The ...
Medical Xpress / Potential therapeutic strategy for Alzheimer's disease improves efficiency of learning and recall
Researchers have found evidence that a therapeutic strategy which makes the brain work more efficiently to learn and recall memories may in fact help to target compromised brain activity in Alzheimer's disease. The study ...
Medical Xpress / Single-cell tool predicts cancer survival by pinpointing harmful tumor cells
Oregon Health & Science University researchers have developed a first-of-its-kind method to predict cancer patient survival using advanced molecular data from individual cells.
Medical Xpress / Chaotic heartbeat patterns track brain activity more clearly than conventional signals, researchers report
A team of researchers at Kyoto University have demonstrated that the chaotic component of heartbeat variability is uniquely sensitive to cognitive brain activity. Conventional heart rate variability, HRV, indices show no ...
Medical Xpress / How a key regulatory protein guides cartilage formation during embryonic development
Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development instead of following a fixed program, as reported by researchers from Science Tokyo. They analyzed mouse ...
Medical Xpress / Early warning signs of brain infection in children identified in new study
Despite new diagnostic methods and expanded vaccination programs, many children in Uganda continue to suffer from severe brain infections, according to a new study from Karolinska Institutet. The researchers' analysis highlights ...
Medical Xpress / How immune cell networks drive liver disease
A type of rare T cell triggers a cascade of signals amplifying inflammation and ultimately leading to liver fibrosis, according to a new study from Julius Maximilian University of Würzburg published in Nature Communications. ...
Medical Xpress / Advanced imaging uncovers immune cells' changing role during glioblastoma invasion
Glioblastoma, the most common and most aggressive brain tumor type in adults, remains difficult to treat because it can infiltrate surrounding brain tissue and spread far beyond the main tumor. Researchers from DZNE, University ...
Medical Xpress / Your liver is hiding a shifting cellular map, and diet can rapidly redraw its internal landscape
As we go about our day, the trillions of cells in our bodies run like well-oiled machines: continually sensing what's happening around them and making modifications to keep us humming along. Like adjusting a gear in a car ...
Medical Xpress / Can a deaf person's brain turn silence into vision?
A brain that develops in the deprivation of one sense reorganizes itself in surprising ways, revealing remarkable neuroplasticity. A team of researchers has studied the brain activity of young congenitally deaf and young ...
