Medical Xpress / Rejuvenating neurons restores learning and memory in mice
Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their connections, a property called ...
Medical Xpress / Can a 'love hormone' drug prevent stress anxiety? What rat tests suggest
Researchers at São Paulo State University (UNESP) in Brazil have demonstrated in rats that a synthetic version of oxytocin can prevent anxiety-related behaviors caused by social stress. The study was published in the journal ...
Medical Xpress / Lucid dreaming could be used for mental health therapy, new study says
Lucid dreaming (LD) is one of the most fascinating parts of human consciousness, where you realize you are actually dreaming while you're still asleep and, in some situations, can decide what happens next. There is a growing ...
Medical Xpress / The truth about energy: Why your 40s feel harder than your 20s, but there may be a lift later on

Medical Xpress / Decades of drinking reshape gene expression in key human brain regions, study shows
Chronic alcohol consumption profoundly alters gene expression in key brain regions involved in reward, impulse control, and decision-making, according to a study led by researchers at the Institute for Neurosciences, a joint ...
Medical Xpress / Maternal perinatal depression may increase the risk of autistic-related traits in girls
A research team from the Department of Psychiatry at Tohoku University, led by Dr. Zhiqian Yu and Professor Hiroaki Tomita, has uncovered compelling evidence that maternal perinatal depression—psychological distress occurring ...
Medical Xpress / Children and adolescents affected by juvenile fibromyalgia are more sensitive to nonpainful sensory stimuli
Children and adolescents affected by juvenile fibromyalgia show greater sensitivity to non-painful sensory stimuli, such as sounds and bright lights. This hypersensitivity is closely related to the severity of the disease ...
Phys.org / Nanobodies: A cure for treatment-resistant depression depression?

Medical Xpress / Both reward and aversion learning require the brain molecule sulfatase 1
Researchers at University of Tsukuba and their collaborators have demonstrated that learning from both rewarding and aversive outcomes requires a common brain molecule, sulfatase 1 (Sulf1). This extracellular enzyme removes ...
Medical Xpress / Can shoes alter your mind? What neuroscience says about foot sensation and focus
Athletic footwear has entered a new era of ambition. No longer content to promise just comfort or performance, Nike claims its shoes can activate the brain, heighten sensory awareness, and even improve concentration by stimulating ...
Medical Xpress / Cellular senescence linked to brain structure changes across lifespan
Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in which aging cells change how they function—is associated with human brain structure in both ...
