Medical Xpress / More than half of hippocampal synapses vanish, yet mouse memories remain intact
How do we remember the distant past? For decades, scientists have believed synaptic potentiation—the adaptive strengthening of our brain's cellular connections—to be the key to memory retention. Researchers from the Okinawa ...
Medical Xpress / Always finish your antibiotics? Longer is better? Outdated ideas about antibiotics are common, study says
"Always finish your antibiotics" is no longer considered medical best practice for all conditions. Surprised? You're not alone.
Medical Xpress / Why brain imaging struggles to identify psychiatric disorder signatures
For decades, neuroscientists have been trying to determine whether different neuropsychiatric conditions are linked to specific variations in brain structure and neural connections. While past studies identified possible ...
Medical Xpress / Potential language-specific brain network identified
The language network in your brain can be seen, even if you aren't saying a word. For a study published in Nature Communications, researchers used data from more than 1,900 functional magnetic resonance imaging (fMRI) scans ...
Medical Xpress / Astrocytes directly regulate brain circuits that consolidate memories during sleep, study reveals
Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals ...
Medical Xpress / Brain cancer cells exploit normal nerve signaling to multiply and invade, new study finds
Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but instead support neurons by maintaining their structure and function. They are the most common form ...
Medical Xpress / Ketamine and psychotherapy show promise as a combined approach to chronic neuropathic pain
Combining ketamine and psychotherapy is a safe and feasible approach with promising benefits for people experiencing chronic neuropathic pain, according to a new study by researchers at St. Michael's Hospital, the University ...
Medical Xpress / New brain map connects mice and primates to strengthen medical research
Most neuroscience research still runs on mice, even though much of what applies to mice does not hold up in humans. Marmosets have emerged as a bridge between species. However, comparing the brains of mice and marmosets runs ...
Medical Xpress / A novel intervention to potentially improve the outcome of children with malnutrition
Researchers at Baylor College of Medicine and Texas Children's Hospital have uncovered an intervention that could potentially improve outcomes for children with malnutrition, a condition that contributes to nearly half of ...
Medical Xpress / Brain circuit keeps tabs on what just happened to aid judgment of what's happening now
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what's going on around it. On the one hand, it has to be open to whatever new sensory information may come its way, ...
Medical Xpress / When phones become an escape: Nomophobia tied to heavier social media use during downtime
Smartphones have become an essential part of everyday life. The anxiety or discomfort experienced when people are unable to use their mobile phones or when their phones are not within reach is known as nomophobia in psychology.
Medical Xpress / 'Locked' cancer therapeutic activates in tumors, limiting off-target exposure in mice
Although there are many cancer treatments available today that effectively eliminate abnormal cells, these therapies may also damage healthy cells, leading to unwanted side effects.
