Discovery improves understanding of Lou Gehrig’s disease

A collaborative study led by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute of Texas Children’s Hospital improves our understanding of how amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease, develops. A common feature of this progressive, fatal neuromuscular condition is an imbalance between the synthesis and […]

Estrogen made by neurons important to making memories

Estrogen in the brain is important to keep neurons communicating and memories being made, scientists report. Neurons in both males and females make estrogen and the scientists have shown that when they don’t, their brains have significantly less dense spines and synapses—both key communication points for neurons—in the biggest part of their brain, called the […]

Study links diabetes and back pain

People with diabetes have a 35 percent higher risk of experiencing low back pain and 24 percent higher risk of having neck pain than those without diabetes, a review by University of Sydney researchers has found. Their findings, based on meta-analyses of studies that assess the links between diabetes and back or neck pain outcomes, […]

Finding the elusive drinking ‘brake’

It’s a common scene in bars and clubs: messy, falling-down drunk, slurring and incoherent, precariously close to catastrophe … and asking the bartender for another shot. For the majority of us who imbibe, there is a certain point at which we stop pounding the drinks, and many reasons we do so. Maybe we sense that […]

Researchers define cells used in bone repair

Research led by Johns Hopkins investigators has uncovered the roles of two types of cells found in the vessel walls of fat tissue and described how these cells may help speed bone repair. The study found that one of these perivascular stem cell types, pericytes, induces growth of new blood vessels, while another type, adventicytes, […]

Research demonstrates that the brain’s primitive sensory region also participates in sophisticated learning

Columbia neuroscientists have revealed that a simple brain region, known for processing basic sensory information, can also guide complex feats of mental activity. The new study involving mice demonstrated that cells in the somatosensory cortex, the brain area responsible for touch, also play a key role in reward learning, the sophisticated type of learning that […]
