A child’s smile is something we take for granted. But muscle dysfunction can turn a simple expression of joy into a challenge. Surface electromyography provides a noninvasive method of sensing muscle activity that can be used for muscle rehabilitation—and to bring a smile to a child’s face.
Scientists are developing profiles of the contents of individual brain cells in a search for the root causes of chronic pain, memory loss and other maladies that affect millions of people.

When a patient undergoes a cardiac catheterization procedure such as a balloon angioplasty, there's a slight risk of a stroke or other neurological complication.
When a stroke patient is discharged from the hospital, they often must cope with a new disability or lack of function, so medication changes can be particularly confusing. But a pilot study that is looking at a new discharge strategy and being led by researchers at Wake Forest Baptist Medical Center, indicates that phone calls and conversations with a “stroke coach” seem to keep a patient on the road to recovery.
Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells “listen in” on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.
UCLA researchers found that older adults who regularly used a brain fitness program played on a computer demonstrated significantly improved memory and language skills.
The greatest risk factor for Alzheimer’s disease (AD) is advancing age. By age 85, the likelihood of developing the dreaded neurological disorder is roughly 50 percent. But researchers at the University of California, San Diego School of Medicine say AD hits hardest among the “younger elderly” – people in their 60s and 70s – who show faster rates of brain tissue loss and cognitive decline than AD patients 80 years and older.
People suffering from the “essential tremor” disorder can now be more easily diagnosed.

New research from Washington University in St. Louis suggests that as much as 10 percent of individual differences in intelligence can be explained by the strength of neural pathways connecting the left lateral prefrontal cortex to the rest of the brain.
Neuroscientists are finding that, as we get older, our aging brains are proving surprisingly malleable, and in ways not previously anticipated. But there are limitations.
Researchers at UCLA have identified a novel molecule in the brain that, after stroke, blocks the formation of new connections between neurons. As a result, it limits the brain’s recovery. In a mouse model, the researchers showed that blocking this molecule—called ephrin-A5--induces axonal sprouting, that is, the growth of new connections between the brain’s neurons, or cells, and as a result promotes functional recovery.
Researchers at Columbia University Medical Center (CUMC) have discovered that some cases of glioblastoma, the most common and aggressive form of primary brain cancer, are caused by the fusion of two adjacent genes. The study also found that drugs that target the protein produced by this genetic aberration can dramatically slow the growth of glioblastomas in mice. The findings were published today in the online edition of the journal Science.

Ever wonder how the human brain, which is constantly bombarded with millions of pieces of visual information, can filter out what’s unimportant and focus on what’s most useful? The process is known as selective attention and scientists have long debated how it works. But now, researchers at Wake Forest Baptist Medical Center have discovered an important clue. Evidence from an animal study, published in the July 22 online edition of the journal Nature Neuroscience, shows that the prefrontal cortex is involved in a previously unknown way.
