Medical Xpress / The brain's primitive 'fear center' is actually a sophisticated mediator, research reveals
A Dartmouth study challenges the conventional view that the amygdala—the two-sided structure deep in the brain involved in emotion, learning, and decision making—is simply the brain's primitive "fear center," reflexively ...
Medical Xpress / Human liver tissue cell architecture reconstructed in 3D at a cellular level
Never-before-seen 3D reconstructions of human liver tissue have been created at a cellular level. The details obtained by a team of UW Medicine and University of Washington engineers and physicians capture the spatial microstructure ...
Medical Xpress / Did you hear about the lab-made ear?
In laboratory experiments, researchers have produced ear cartilage that remains form-stable in animal models. Only one element is missing to make the tissue as elastic as a natural ear.
Medical Xpress / Novel markers of brain blood flow and oxygenation may offer early clues to Alzheimer's risk
Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics ...
Medical Xpress / Engineered immune therapy could help fight brain aging
Researchers with the Knight Initiative for Brain Resilience have modified a well-known immune protein to spark the growth of new neurons, ease brain inflammation, and improve cognition in old mice. The findings, published ...
Medical Xpress / Children born with upper limb difference show the incredible adaptability of the young brain
A unique study imaging brain activity in children born with upper limb difference—for example, one hand—has shown the amazing ability of the brain to adapt to compensate and support their daily lives. The research, led ...
Medical Xpress / Dopamine selects, astrocytes refine: A new mechanism for motor-learning circuit rewiring
When we learn a new motor skill—whether mastering a piano passage or refining balance while walking—the brain must reorganize the circuits that control movement. For decades, this process of synaptic remodeling has been ...
Medical Xpress / Study finds that telemedicine visits cost far less than office visits
Telemedicine visits are five times less costly than in-person appointments for the most common conditions able to be treated by both forms of visits, new research from the Perelman School of Medicine at the University of ...
Medical Xpress / Kenya-Uganda trial reduces HIV incidence by 70% in rural populations
By pairing digital tools with tailored HIV services delivered by community health workers and clinicians, a study has reduced new HIV cases by 70% in rural Kenya and Uganda. This successful strategic implementation of existing ...
Medical Xpress / Ultrasound gives the brain a nudge in the right direction
Neuroscientist Soha Farboud of the Donders Institute at Radboud University has succeeded in adjusting activity in specific brain areas using a new technique. With ultrasonic brain stimulation, she was able to influence whether ...
Medical Xpress / Obstructive sleep apnea may cost UK and US economies billions in lost productivity
Untreated obstructive sleep apnea may be costing the UK and US economies billions of pounds/dollars in lost productivity every year, with a considerable proportion of working-age adults experiencing symptoms indicative of ...
Medical Xpress / Dysregulation of the immune system differentiates depression and psychosis in young adulthood
In the early phases of depression and psychosis, patients often show altered inflammatory markers in the blood and structural changes in the gray matter of the brain. This was demonstrated in the international study entitled ...
