Published A subtype of depression identified (via sciencedaily.com) Original source
Using surveys, cognitive tests and brain imaging, researchers have identified a type of depression that affects about a quarter of patients. The goal is to diagnose and treat the condition more precisely.
Published The molecular control center of our protein factories (via sciencedaily.com) Original source
Researchers have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.
Published Chronic stress-related neurons identified (via sciencedaily.com) Original source
Researchers have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for estrogen, which could explain why women as a group are more sensitive to stress than men.
Published Studying herpes encephalitis with mini-brains (via sciencedaily.com) Original source
The herpes simplex virus-1 can sometimes cause a dangerous brain infection. Combining an anti-inflammatory and an antiviral could help in these cases, report scientists.
Published Unraveling the connections between the brain and gut (via sciencedaily.com) Original source
Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and the brain, in mice.
Published Omega-3 fatty acids linked to slower decline in ALS (via sciencedaily.com) Original source
People with amyotrophic lateral sclerosis (ALS) who eat more foods high in certain omega-3 fatty acids like flaxseed oil, walnuts, canola oil and pumpkin seeds may have a slower physical decline from the disease and may have a slightly extended survival. Researchers also found an omega-6 fatty acid may be beneficial. The study does not prove that these omega fatty acids slow decline of ALS or extend survival; it only shows an association.
Published Restoring the blood-brain barrier? (via sciencedaily.com) Original source
Scientists discover a treatment in mice to repair the blood-brain barrier, which is key to brain health.
Published Everyone's brain has a pain fingerprint -- new research has revealed for the first time (via sciencedaily.com) Original source
New research has revealed everyone's brain has a 'pain fingerprint' that varies from person to person.
Published Brain receptor patterns separate sensory and cognitive networks (via sciencedaily.com) Original source
Receptor patterns define key organizational principles in the brain, scientists have discovered.
Published Scientists discover spiral-shaped signals that organize brain activity (via sciencedaily.com) Original source
Scientists have discovered human brain signals traveling across the outer layer of neural tissue that naturally arrange themselves to resemble swirling spirals.
Published Astrocyte processing of serotonin regulates olfactory perception (via sciencedaily.com) Original source
Researchers have uncovered novel aspects of astrocyte function in olfactory, or smell, perception revealing changes in their gene expression patterns that turn these brain cells into a hub of olfactory sensation processing.
Published Pregnancy hormone repairs myelin damage in MS mouse model (via sciencedaily.com) Original source
A new study has identified a treatment that could repair myelin in the cortex, undoing some of the damage caused by MS.
Published New discovery can help detect brain tumors (via sciencedaily.com) Original source
Folate-based radiopharmaceuticals can be used in positron emission tomography (PET) imaging to detect folate receptors in brain tumours. The discovery of folate receptors and their exploitation potential with respect to brain tumours is a new and significant finding in the field.
Published A 'pinch' of mineral salts helps the noncaloric sweeteners go down (via sciencedaily.com) Original source
Perfect noncaloric replacements for sugar and high fructose corn syrup just don't exist yet. For example, some alternatives have a lingering sweet aftertaste and lack a sugar-like mouthfeel, leaving some consumers unsatisfied. Now, researchers propose adding blends of nutritionally important mineral salts to make noncaloric sweeteners seem more like the real thing. Taste-testers indicated that these blends gave zero- and low-calorie drinks a better flavor.
Published Video games spark exciting new frontier in neuroscience (via sciencedaily.com) Original source
Researchers have used an algorithm from a video game to gain insights into the behavior of molecules within live brain cells. Researchers used coding tools to build an algorithm that is now used by several labs to gather rich data about brain cell activity. The algorithm was applied to observe molecules clustering together -- which ones, when, where, for how long and how often.
Published AI helps show how the brain's fluids flow (via sciencedaily.com) Original source
A new, AI-based technique for measuring fluid flow in the brain could lead to treatments for diseases such as Alzheimer's.
Published Biodegradable ultrasound opens the blood-brain barrier (via sciencedaily.com) Original source
A new, biodegradable ultrasound far more powerful than previous devices could make brain cancers more treatable, researchers report.
Published New images capture unseen details of the synapse (via sciencedaily.com) Original source
Scientists have created one of the most detailed 3D images of the synapse, the important juncture where neurons communicate with each other through an exchange of chemical signals. These nanometer scale models will help scientists better understand and study neurodegenerative diseases such as Huntington's disease and schizophrenia.
Published Serotonin booster leads to increased functional brain connectivity (via sciencedaily.com) Original source
Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects. Limited treatments currently exist, but studies in animals and humans have pointed to drugs such as the laxative prucalopride that activate serotonin receptors as a potential therapeutic for the symptoms. It has remained unclear, however, how the medication affects resting brain activity. Now, a new study examines the drug's effects in healthy human adults.
Published Can this medication reverse MS? Brain biomarker shows it can (via sciencedaily.com) Original source
A decade after scientists identified an over-the-counter antihistamine as a treatment for multiple sclerosis, researchers have developed an approach to measure the drug's effectiveness in repairing the brain, making it possible to also assess future therapies for the devastating disorder.
