Wayne State University researcher invited to edit book on neuropsychiatry
A Wayne State University School of Medicine faculty member is editor of a newly published book, Brain Network Dysfunction in Neuropsychiatric Illness: Methods, Applications & Implications, published by Springer Nature Publishing.
Rutgers Opens Center for Advanced Human Brain Imaging Research
Rutgers Biomedical and Health Sciences has opened a new brain imaging research center to improve the diagnosis of neurological and psychiatric disorders and to help personalize and monitor treatments.
JFK University Medical Center First Hospital in New Jersey to Utilize New Portable MRI
Hackensack Meridian JFK University Medical Center is the first hospital in New Jersey to operate a new portable MRI that can be wheeled to the bedside of critically ill patients. The world’s first portable MRI called Swoop™, enables clinicians to obtain neurological images of critically ill patients at the point of care quickly and conveniently.
Shine On: Avalanching Nanoparticles Break Barriers to Imaging Cells in Real Time
A team of researchers co-led by Berkeley Lab and Columbia University has developed a new material called avalanching nanoparticles that, when used as a microscopic probe, offers a simpler approach to taking high-resolution, real-time snapshots of a cell’s inner workings at the nanoscale.
Which OCD treatment works best? New brain study could lead to more personalized choices
New research could improve the odds that people with obsessive-compulsive disorder will receive a therapy that really works for them – something that eludes more than a third of those who currently get OCD treatment. The study suggests the possibility of predicting which of two types of therapy will help people with OCD: One that exposes them to the subject of their obsessive thoughts and behaviors, or one that focuses on stress reduction and problem-solving.
Scanning the Brain to Predict Behavior, a Daunting ‘Task’ for MRI
To study the brain “in action,” researchers use a specialized form of brain imaging known as task-based functional MRI (task-fMRI), which shows how the brain responds to stimuli. While this technique can reveal much about the general workings of the average human brain, new research indicates that task-fMRI lacks the reliability to predict individual behavior or how a person might respond to mental-health therapies.
Cumulative Effects of Long Term Alcohol on Brain Function
Functional MRI (fMRI), a type of scan that measures brain activity, has enabled study of the impact of alcohol on brain function. This type of imaging allows brain activity to be assessed while participants are at rest, performing a simple task like tapping a finger, or doing a complex cognitive task like a memory task or decision-making. It works by detecting the change in blood flow that occurs when brain cells (or neurons) in different parts of the brain are activated. Blood flow provides the energy and oxygen needed for brain cells to activate, and it is this exchange of oxygen that is measured using fMRI and is reflected by brain blood flow. Complicated physics are involved in determining the profile of blood flow when a part of the brain is activated, and studies have shown that the time course of these changes – known as the hemodynamic response function (HRF) – is affected by acute alcohol consumption. However, the effects of heavy chronic (long-term) alcohol consumption on HRF
Brain Scan-Blood Test Panel Promises Improved Diagnosis of Brain Trauma Following Battlefield Blast Exposure
New brain scans and blood tests move researchers towards more sensitive diagnosis of battlefield brain trauma and evaluation of new drugs
To BOLDly Go (or No-go): Brain imaging predicts frequent binge drinking in adolescents
A study published in the journal Alcoholism: Clinical and Experimental Research could inform efforts to prevent adolescents from escalating to harmful patterns of drinking. Binge drinking in adolescence has many short- and long-term heath consequences, including risk of future alcohol use disorder and potential for harm to the developing brain. The risks are greatest for those who binge frequently – at least once a week. A hallmark of binge drinking is a reduced capacity to control one’s alcohol intake, related to a neurological process of ‘inhibitory control’ involving several regions of the brain. In adolescents who have not yet started drinking, specific alterations in these brain responses have been linked to an increased risk of future alcohol and drug use; however, it was not known if there are changes that could predict escalation of alcohol use among those already drinking. Therefore, researchers from the University of California investigated whether abnormal brain patterns co
