New method can detect and monitor pH changes in living brains

University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too.

Strong link between the amygdala and a baseline level of distrust

Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with declarative memory and the recognition of scenes.

TJU researchers to investigate Cu-64 imaging agent for prostate cancer

Jefferson's Kimmel Cancer Center and the Department of Radiology at Thomas Jefferson University received a five-year, $2.6 million grant from the National Institutes of Health (NIH) to investigate a potentially revolutionary method that can stage prostate cancers and detect recurrent disease so accurately, it would significantly reduce the number of confirmation biopsies. Such biopsies can be invasive, costly, and often lead to false-positive readings.

CU scientist looks at reward circuits in the brain

Why does one person become anorexic and another obese? A study recently published by a University of Colorado School of Medicine researcher shows that reward circuits in the brain are sensitized in anorexic women and desensitized in obese women.

Excess brain activity contributes to amnestic mild cognitive impairment

A study led by a Johns Hopkins neuroscientist and published in the May 10 issue of the journal Neuron suggests a potential new therapeutic approach for improving memory and interrupting disease progression in patients with a form of cognitive impairment that often leads to full-blown Alzheimer's disease.

IGABT effective at controlling return and spread of cervical cancer

Delivering radiotherapy directly to cancer of the cervix using 3-D imaging techniques is effective at controlling the return and spread of the disease and, in most cases, avoids the need for hysterectomies, according to research presented at the World Congress of Brachytherapy today.

Study compares three new methods to study disorders of consciousness

Disorders of consciousness such as coma or a vegetative state caused by severe brain injury are poorly understood and their diagnosis has relied mainly on patient responses and measures of brain activity. However, new functional and imaging-based diagnostic tests that measure communication and signaling between different brain regions may provide valuable information about the potential for consciousness in patients unable to communicate. These innovative approaches are described and compared in a Review article in the groundbreaking neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

Study shows effects of psychotropic drug treatment on brain morphology

It is increasingly recognized that chronic psychotropic drug treatment may lead to structural remodeling of the brain. Indeed, clinical studies in humans present an intriguing picture: antipsychotics, used for the treatment of schizophrenia and psychosis, may contribute to cortical gray matter loss in patients, whereas lithium, used for the treatment of bipolar disorder and mania, may preserve gray matter in patients.

Psychopaths’ brains differ from healthy non-offenders: Study confirms

Approximately half of male prisoners in England and Wales will meet diagnostic criteria for ASPD. The majority of such men are not true psychopaths (ASPD-P). They are characterized by emotional instability, impulsivity and high levels of mood and anxiety disorders. They typically use aggression in a reactive way in response to a perceived threat or sense of frustration.

Researchers find talking about ourselves triggers sensation of pleasure

According to researchers, talking about ourselves - whether in a personal conversation or through social media sites like Facebook and Twitter - can trigger the same sensation of pleasure in the brain as food, money or sex.

High fructose intake may increase risk of NFALD in obese people

Obese people who consume increased amounts of fructose, a type of sugar that is found in particular in soft drinks and fruit juices, are at risk for nonalcoholic fatty liver disease (NFALD) and more its more severe forms, fatty inflammation and scarring.

Biosynthetic polyphenol may improve cognitive function in Alzheimer's disease patients

Mount Sinai School of Medicine researchers have succeeded in developing a biosynthetic polyphenol that improves cognitive function in mice with Alzheimer's disease (AD). The findings, published in a recent issue of the Journal of Neuroscience, provide insight in determining the feasibility of biosynthetic polyphenols as a possible therapy for AD in humans, a progressive neurodegenerative disease for which there is currently no cure.

Researchers examines whether MRI can improve accuracy of Huntington’s diagnosis

Huntington disease (HD) is an inherited neurodegenerative disorder caused by a defect on chromosome four where, within the Huntingtin gene, a CAG repeat occurs too many times. Most individuals begin experiencing symptoms in their 40s or 50s, but studies have shown that significant brain atrophy occurs several years prior to an official HD diagnosis. As a result, the field has sought a preventive treatment that could be administered prior to the development of actual symptoms that might delay the onset of illness.
