Medical News Today: These neurons make us fall asleep when we are bored

If you have fallen asleep during a meeting, don’t blame yourself: blame your neurons. Specifically, a set of neurons in a brain area known as the nucleus accumbens, which is a region known to play a role in motivation and reward. This is what a study recently published in the journal Nature Communications seems to […]

Medical Xpress: Study shows how ‘love hormone’ oxytocin spurs sociability

Why is it so much fun to hang out with our friends? Why are some people so sociable while others are loners or seemingly outright allergic to interactions with others? A new study by researchers at the Stanford University School of Medicine begins to provide an answer, pinpointing places and processes in the brain that […]

New Atlas: Appetite-controlling brain cells activated by amino acids

You’ve likely heard that eating protein can fill you up faster than eating simple carbs like bread and pasta. Now, researchers at the University of Warwick (UW) in England have figured out just why that is, and they’ve identified the specific foods that satisfy hunger the quickest. Their findings could put a serious dent in […]

Futurism: We finally have a way to detect brain damage from concussions in living brains

Chronic Traumatic Encephalopathy (CTE) is a devastating, degenerative neurological condition that strikes athletes who play contact sports, veterans who’ve seen combat, and domestic violence survivors, among others. CTE can affect anyone whose brain sustains too much trauma, even multiple “mild” concussions—but thus far, there’s no way to diagnose the disease until after death, when it’s […]

Reuters: Stopping aspirin therapy may raise heart attack, stroke risk

Stopping low-dose aspirin therapy without good reason raises the likelihood of heart attack or stroke by nearly 40 percent, a large Swedish study suggests. Doctors commonly prescribe daily low-dose aspirin after a heart attack to reduce the risk of having a second cardiovascular event. But about one in six patients stop taking their aspirin within […]

Science Daily: New role for fragile X protein could offer clues for treatment

The protein behind fragile X syndrome acts as a genetic conductor, orchestrating a symphony of genes that help shape DNA’s 3-D structure. Fragile X mental retardation protein, or FMRP, oversees a set of genes that alter how DNA is packaged, researchers report September 7, 2017 in the journal Cell. This is an important new role […]

UPI: Breakdown of metabolic collaboration of brain cells tied to Alzheimer’s

Baylor College of Medicine researchers have discovered that impairing a vital collaboration between brain cells leads to neurodegeneration. The study, published Thursday in Cell Metabolism, shows the mechanism that two types of brain cells — neurons and glia — use to support each other’s functions. If the mechanism fails, neurodegeneration occurs. (September 29, 2017) Read […]

Medical News Today: Brain circuit that makes you crave salt identified

Salt is not all bad, but too much of it can have a serious impact on your cardiovascular health. Reducing our salt intake can seem challenging, however, and new research maps the neurons that make passing up salt so difficult. A moderate amount of salt is crucial to our health. The sodium found in salt […]
