Interventions for anxiety may help people with autism spectrum disorder
A new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging reports that anxiety occurring in autism spectrum disorder (ASD) shares similar brain mechanisms as anxiety alone. Led by Drs. John Herrington and Robert Schultz of the Center for Autism Research, a joint research center of the Children's Hospital of Philadelphia and University of Pennsylvania, the study could be good news for treating anxiety symptoms in ASD. The findings suggest that treatments that work for anxiety disorders may also help people with anxiety and ASD.

Patient plays saxophone while surgeons remove brain tumor
Music is not only a major part of Dan Fabbio's life, as a music teacher it is his livelihood. So when doctors discovered a tumor located in the part of his brain responsible for music function, he began a long journey that involved a team of physicians, scientists, and a music professor and culminated with him awake and playing a saxophone as surgeons operated on his brain.

Gut microbes may talk to the brain through cortisol
Gut microbes have been in the news a lot lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain? Results from a new University of Illinois study suggest a pathway of communication between certain gut bacteria and brain metabolites, by way of a compound in the blood known as cortisol. And unexpectedly, the finding provides a potential mechanism to explain the characteristics of autism.

Yoga may boost aging brains
(HealthDay)—Older women who practice yoga may have greater "thickness" in areas of the brain involved in memory and attention, a small study suggests.

How rhyming helps reading
When, in the nursery rhyme, Jack and Jill go up a hill, they're teaching children more than how to fetch a pail of water. They're also improving their reading skills.

Clinical trial for first-ever treatment of radiation necrosis
Radiation therapy saves countless lives, but in rare cases, it can cause a debilitating, long-term complication when used on the brain. Around three to five percent of patients who receive radiation for brain tumors, or arteriovenous malformations (AVM), develop radiation necrosis, where the brain tissue around the targeted lesion becomes injured and dies.

Compound suggests pain treatment without opioid or medical marijuana side effects
Indiana University neuroscientist Andrea Hohmann took the stage at a press conference Nov. 14 in San Diego to discuss research conducted at IU that has found evidence that the brain's cannabis receptors may be used to treat chronic pain without the side effects associated with opioid-based pain relievers or medical marijuana.

Out of tune: Mismatch of vascular and neural responses suggests limits of fMRI
In an article published online ahead of print on May 25, 2016 in Nature, investigators at the Medical University of South Carolina (MUSC) report that, during sensory stimulation, increases in blood flow are not precisely "tuned" to local neural activity, challenging the long-held view that vascular and local neural responses are tightly coupled.

Are stem-cell therapies for Parkinson's disease ready for clinical trials?
As stem cell-based therapies are moving rapidly towards clinical trials, treatments for Parkinson's Disease (PD), an incurable condition, may be on the horizon. A recent announcement of a Phase I/IIa clinical trial involving transplantation of stem cells into the first human subjects has raised hope among patients and sparked discussions in the research community. In a commentary published in the Journal of Parkinson's Disease, authors propose five key questions that should be addressed as this trial begins.

Lack of sleep tampers with your emotions
Cranky or grumpy after a long night? Your brain's ability to regulate emotions is probably compromised by fatigue. This is bad news for 30 percent of American adults who get less than six hours of sleep per night, according to the Centers for Disease Control and Prevention.

Can you think yourself into a different person?
For years she had tried to be the perfect wife and mother but now, divorced, with two sons, having gone through another break-up and in despair about her future, she felt as if she'd failed at it all, and she was tired of it. On 6 June 2007 Debbie Hampton, of Greensboro, North Carolina, took an overdose of more than 90 pills – a combination of ten different prescription drugs, some of which she'd stolen from a neighbour's bedside cabinet. That afternoon, she'd written a note on her computer: "I've screwed up this life so bad that there is no place here for me and nothing I can contribute." Then, in tears, she went upstairs, sat on her bed, swallowed her pills with some cheap Shiraz and put on a Dido CD to listen to as she died. As she lay down, she felt triumphant.

Premature birth appears to weaken brain connections
Babies born prematurely face an increased risk of neurological and psychiatric problems that may be due to weakened connections in brain networks linked to attention, communication and the processing of emotions, new research shows.

Researcher discusses neuroscience history and new hope for autistic people
To mark the publication of the book NeuroTribes (Aug 25, 2015; Avery/Penguin Random House) by Steve Silberman, whose blog of the same name has been hosted on the PLOS BLOGS Network since 2010, we invited independent science writer Emily Willingham, PhD to review the book and conduct an in-depth interview with the author. Willingham's review and interview follow, with her full bio at the bottom of this post.

Intellectual pursuits may buffer the brain against addiction
Challenging the idea that addiction is hardwired in the brain, a new UC Berkeley study of mice suggests that even a short time spent in a stimulating learning environment can rewire the brain's reward system and buffer it against drug dependence.

Possible progress against Parkinson's and good news for stem cell therapies
Brazilian researchers at D'OR Institute for Research and Education (IDOR) and Federal University of Rio de Janeiro (UFRJ) have taken what they describe as an important step toward using the implantation of stem cell-generated neurons as a treatment for Parkinson's disease. Using an FDA approved substance for treating stomach cancer, Rehen and colleagues were able to grow dopamine-producing neurons derived from embryonic stem cells that remained healthy and functional for as long as 15 months after implantation into mice, restoring motor function without forming tumors.

UM brain disorder research moves toward clinical testing
University of Montana is one step closer to turning a discovery into a drug. Promentis Pharmaceuticals, Inc. recently announced it will enter an exclusive agreement with UM to commercialize a discovery made by a team of UM faculty scientists that has the potential to treat brain cancer and possibly other disorders of the central nervous system.
