Research suggests oxytocin as potential new obesity treatment

The hormone oxytocin reduces the communication between different brain areas involved in the cognitive, sensory and emotional processing of food cues that people with obesity demonstrate when they look at high-calorie foods, according to research being presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

New research illuminates positive effects of exercise on the brain

Anyone who trains for a marathon knows that individual running workouts add up over time to yield a big improvement in physical fitness.

Research links participation in team sports to larger hippocampal volumes in children

Adult depression has long been associated with shrinkage of the hippocampus, a brain region that plays an important role in memory and response to stress. Now, new research from Washington University in St. Louis has linked participation in team sports to larger hippocampal volumes in children and less depression in boys ages 9 to 11.

Study: Perivascular spaces contribute to worse cognitive health in older adults

Seemingly harmless fluid-filled spaces around the cerebral small vessels, commonly seen on brain MRIs in older adults, are now thought to be associated with more compromised cognitive skills, according to a Vanderbilt University Medical Center study published in Neurology.

Participation in sports linked with fewer depressive symptoms in children

Participation in team sports is associated with fewer depressive symptoms in children, whereas non-sport activities have no association with symptoms, according to a study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier.

Butler Hospital receives COBRE grant to enhance research on neuropsychiatric illnesses

Neuropsychiatric illnesses are common and highly impairing conditions that arise from abnormal functioning of the brain.

Diattenuation Imaging offers structural information of difficult to access brain regions

A new imaging method provides structural information about brain tissue that was previously difficult to access. Diattenuation Imaging, developed by scientists at Forschungszentrum Jülich and the University of Groningen, allows to differentiate, e.g., regions with many thin nerve fibers from regions with few thick nerve fibers.

Study unravels mystery behind how the brain encodes time when forming long-term memories

The way we encode our memories involves many pieces of information, and scientists have looked at how most of them work. But one dimension still eludes them: time.

Stanford researchers detail how hits to the side of the head cause concussion

Concussion researchers have long suggested that damage to the corpus callosum, a thick bundle of nerves that connects the brain's two halves, could result in some common side effects of concussion, like dizziness or vision problems.

Discarding information from the brain linked to more mental effort, finds study

Discarding information from the brain is associated with more mental effort than keeping it, finds a human neuroimaging study published in JNeurosci.

Intentional forgetting may take more mental effort than remembering

Choosing to forget something might take more mental effort than trying to remember it, researchers at The University of Texas at Austin discovered through neuroimaging.

People exposed to trauma have less ability to suppress unwanted memories

People exposed to trauma are less able to suppress unwanted emotional memories due to neural and behavioral disruptions in their brain that may contribute to the development of post-traumatic stress disorder.

Scientists develop tool to screen children for fetal alcohol spectrum disorder

Scientists at the University of Southern California, Queen's University and Duke University have developed a new tool that can screen children for fetal alcohol spectrum disorder quickly and affordably, making it accessible to more children in remote locations worldwide.

National Multiple Sclerosis Society awards grant for pilot study of social interaction in individuals with MS

Ekaterina Dobryakova, PhD, and Pei-Pei Liu, PhD, were awarded a $50,000 grant from the National Multiple Sclerosis Society to conduct a novel study of outcome processing in individuals with MS.

Study emphasizes real-time eye contact as basis for effective social interaction

In contrast to studies of mice and rats, new research published in eNeuro investigating the effect of methylphenidate (Ritalin) on neuronal activity in monkeys has found no effect of the drug on the prefrontal cortex.

Autistic children with co-occurring ADHD have greater adaptive behavior impairments

A pair of new studies has provided new insight into the challenges faced by children on the autism spectrum who exhibit symptoms of attention deficit/hyperactivity disorder.

New injury documentation tool may provide better evidence for elder abuse cases

An estimated 10 percent of older adults experience some form of abuse each year. However, the link between injuries and possible elder abuse may take months or years to establish and is often difficult to investigate due to poor documentation during prior medical visits.

Lifetime adversity, increased neural processing during trauma combine to intensify core PTSD symptoms

Lifetime adversity and increased neural processing during a traumatic event combine to increase the frequency of intrusive traumatic memories and the distress they cause, according to a new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

USC researchers use AI to identify blood-based markers of Alzheimer's disease

Nearly 50 million people worldwide have Alzheimer's disease or another form of dementia. While age is the greatest risk factor for developing the disease, researchers believe most Alzheimer's cases occur as a result of complex interactions among genes and other factors. But those factors and the role they play are not known--yet.
