Ketamine, A Promising Depression Treatment, Seems To Act Like An Opioid
A new study suggests that ketamine, an increasingly popular treatment for depression, has something in common with drugs like fentanyl and oxycodone.
Opioid system plays key role in ketamine’s antidepressant effects, Stanford study finds
For about a dozen years now, the drug ketamine has been a buzz word in psychiatric research circles. Many considered it the most exciting thing to emerge in decades to successfully treat treatment-resistant depression as well as other severe forms of psyc
America’s Invisible Pot Addicts
More and more Americans are reporting near-constant cannabis use, as legalization forges ahead.
Expanded Awareness: Turning the Tables on Your Brain
Sometimes the enormous success of science leads to some wrong assumptions. In the case of brain science, the advent of sophisticated brain scans opened a window to the brain as never before.
To help patients quash pain, researcher develops practical guide for health care providers
In a new book, Stanford pain psychologist Beth Darnall offers practical tools for health care providers to help their patients reduce pain.
Better health might depend on a good night’s sleep
Getting a sound night’s sleep is important for good health. But, sometimes older adults get much less sleep than they need. Health experts say seniors could sleep better if they made some simple changes.
On/off sociability switch in brain identified, could play a role in autism
The release of a single signaling chemical from a specific nerve-cell tract in a particular part of the brain, like an on/off switch, may spell the difference between sociability and social awkwardness.
Scientists tie specific brain circuit to sociability in mice
Autism spectrum disorder is marked by severe social deficits. Stanford researchers were able to reverse those types of deficits in mice by activating a single brain circuit.
Reaching for new stroke treatments by understanding proprioception
Stanford mechanical engineering PhD student Sean Sketch is working to better understand proprioception — in the hope of one day helping people for whom sense has been impaired by stroke or other diseases.
A nanoparticle opens new windows into neuroscience and biology
Neurons in the brain and body send chemical signals from one to the next. Now, scientists led by Stanford's Steven Chu are a step closer to watching those signals take shape inside individual neurons.
Stanford researchers start concussion study with high school athletes
A Palo Alto company is teaming up with a Stanford health care network and several regional high schools for a study that will use virtual reality headsets to track eye movements to better spot concussions.
5 Questions: Robert Fisher on deep-brain stimulation for drug-resistant epilepsy
The FDA has approved the use of an implanted device that releases periodic electrical discharges in the brain to counteract seizures in people with epilepsy. In an interview, neurologist Robert Fisher described the technology and Stanford’s role in testin
Study links depression to low blood levels of acetyl-L-carnitine
Investigators at Stanford and elsewhere have shown, for the first time in humans, that low blood levels of acetyl-L-carnitine track with the severity and duration of depression.
“Mood mirror” in blood: Might its absence bring on the blues?
Stanford psychiatric researcher Natalie Rasgon, MD, PhD, and her collaborators in a multicenter study have identified a substance, acetyl-L-choline, whose levels in the blood of people suffering from depression are correspondingly depressed.
How you get around depends on how fast you’re moving
Stanford neuroscientist Lisa Giocomo, PhD, and her colleagues examined the navigational behavior and brain-activity patterns of mice traveling through a virtual reality environment.
Virtual athletes compete to take on a medical challenge
ŁUKASZ KIDZIŃSKI, a postdoctoral scholar in bioengineering at Stanford, cooked up a contest with a serious goal: designing better prosthetic limbs and helping patients adapt to them.
Virtual athletes compete to take on a medical challenge
Lukasz Kidziński hit on the idea of a competition, in which teams from around the world would compete to design artificial intelligence algorithms that would, along with virtual bodies informed by Scott Delp’s data and models, learn to walk, run and event
What happens when you take a bunch of medications? A new algorithm could help doctors figure it out
Researchers Marinka Zitnik, PhD; Monica Agrawal; and Jure Leskovec, PhD, have designed a new system to deal with the literally billions of possibilities when considering any two drugs — out of about 5,000 on the U.S. market — and one of around a thousand
