Some post-surgery alternatives to opioids can reduce pain, study finds
Researchers examined the most commonly used non-pharmaceutical pain management therapies following knee replacement surgery to see if they did indeed work to reduced pain while the patient was in the hospital. They found that acupuncture and electrotherap
Long-term, 3-D culture method lets slow-developing brain cells mature in a dish
Stanford researchers have used a revolutionary 3-D culture technique to nurse a very slowly developing set of brain cells known as astrocytes to maturity in laboratory glassware.
Open contest with skeleton videos may help people learn, or relearn, to walk
If you’re a scientist who wants to do something to help kids with cerebral palsy, your first strategy probably isn’t to launch an internet contest with freaky skeleton videos, but that is more or less what Łukasz Kidziński, PhD, did.
Does autism reflect an excitation-inhibition imbalance in the brain?
A Stanford study suggests that aspects of autism reflect a signaling imbalance in certain neurons in the forebrain. Could reversing this imbalance alleviate some symptoms?
Stanford bioengineers encourage virtual competitors to vie for a different kind of athletic title
Better models of the bone, muscles and nerves that control our bodies could help doctors manage movement disorders like cerebral palsy. A new competition is crowdsourcing the search for those tools.
Jennifer Cochran appointed chair of bioengineering
Jennifer Cochran, whose research focuses on development of new technologies for high-throughput protein analysis and engineering, succeeds Norbert Pelc.
Autism may reflect excitation-inhibition imbalance in brain
Stanford researchers used advanced lab technologies to show, in mice, that symptoms of autism can be countered by reducing the ratio of excitatory to inhibitory neuronal firing in the forebrain.
Correcting a forebrain signaling imbalance reverses autistic symptoms in mice
A new study, conducted by Stanford psychiatrist, neuroscientist and inventor Karl Deisseroth, MD, PhD, and colleagues, suggests that key features of autism reflect an imbalance in signaling from two kinds of neurons in a portion of the forebrain.
Researchers identify biomarkers associated with chronic fatigue syndrome severity
Stanford investigators used high-throughput analysis to link inflammation to chronic fatigue syndrome, a difficult-to-diagnose disease with no known cure.
Blood test: Scientists crack code of chronic fatigue syndrome’s inflammatory underpinnings
A new study led by Stanford chronic fatigue syndrome expert Jose Montoya, MD, has linked chronic fatigue syndrome to variations in 17 immune-system signaling proteins, or cytokines, whose concentrations in the blood correlate with the disease’s severity.
The mouse that didn’t roar: Dormitory housing defuses hardwired male territorial aggression
Male mice are naturally territorial. In the wild or in the lab, they attack other male mice even if plenty of room, food and females are available. This behavior is under the control of a small nerve circuit in the male mouse’s brain; disabling the circui
Social influences can override aggression in male mice, study shows
A tiny set of nerve cells in a male mouse’s brain activates aggression. But a new Stanford study shows that the male’s susceptibility to this activation depends on whether it has been housed with other mice or in isolation.
Late-night serendipity yields new insight Into Alzheimer’s disease
A Stanford team found that amyloid beta did not form into the plaques and fibrils characteristic of Alzheimer’s disease when in the presence of cathelicidin. Instead, the results indicate the two compounds form a stable non-toxic complex.
Brain scans shown to predict how well PTSD patients respond to therapy
Using neuroscience to help determine the best treatment plans for patients with psychiatric conditions — everything from depression to anxiety to bipolar disorder — is a growing area of research in a field that is in desperately in need of better treatmen
Addiction policies should accord with neuroscience, Stanford researchers argue
Addiction, like riding a bike, is a learned behavioral pattern you don’t unlearn even if you haven’t performed it for decades. Your brain’s semi-permanently hot-wired reward system has to be stripped down, reordered, and re-insulated again.
Stanford researchers say U.S. policies on drugs and addiction could use a dose of neuroscience
Legal and illegal drugs are killing more people than AIDS ever did, yet the nation’s drug policies are based on unproven assumptions about addiction. Neuroscience could help shape more effective policies and save lives.
Inside the heads of men and women: A look at sex-based cognitive differences
New technologies and new hypotheses have generated a growing pile of evidence that there are inherent differences in how men’s and women’s brains are wired and how they work.
Memory lane
Ever wish you were one of those people who could quickly memorize the order of all the cards in a deck? You can be, according to researchers from the Stanford School of Medicine and from the Donders Institute for Brain, Cognition and Behavior in the Nethe
Think typing
One rainy day in October 2007, Dennis Degray was taking out the trash when he slipped, fell and landed on his chin. He severely injured his spinal cord, becoming paralyzed from the neck down. “I’ve got nothing going on below the collarbones,” he says.
