FOXO1 gene may play an important role in pathological mechanisms of Parkinson's

A recent study led by researchers at Boston University School of Medicine (BUSM) revealed that the FOXO1 gene may play an important role in the pathological mechanisms of Parkinson's disease.

Blindsight in monkeys is available in everyday environments

The visual information from eyes is sent into the brain unconsciously even if you are not aware. One of examples of unconscious seeing is a phenomenon of "blindsight" [Subjects have no awareness, but their brains can see] in subjects with visual impairment, caused by the damage of a part of the brain called the visual cortex.

Why our eyes are bigger than our stomachs

Viewing images of high-calorie foods can trigger hunger cravings, suggests research presented at the Endocrinology Society’s annual meeting ENDO 2012 in Houston, Texas, USA.

Gene transfer technique eliminates specific neural circuit linked to Parkinson's disease

In the brains of humans and non-human primates, over 100 billion nerve cells build up complicated neural circuits and produce higher brain functions. When an attempt is made to perform gene therapy for neurological diseases like Parkinson's disease, it is necessary to specify a responsible neural circuit out of many complicated circuits.

Study reveals function of dorsal anterior cingulate cortex in the brain

Every day the human brain is presented with tasks ranging from the trivial to the complex. How much mental effort and attention are devoted to each task is usually determined in a split second and without conscious awareness. Now a study from Massachusetts General Hospital (MGH) researchers finds that a structure deep within the brain, believed to play an important role in regulating conscious control of goal-directed behavior, helps to optimize behavioral responses by predicting how difficult upcoming tasks will be.

Scientists identify cause of double-cortex syndrome

Researchers at McGill University have discovered the cause of an inherited form of epilepsy. The disease, known as double-cortex syndrome, primarily affects females and arises from mutations on a gene located on the X chromosome. Drs. Susanne Bechstedt and Gary Brouhard of the Department of Biology have used a highly advanced microscope to discover how these mutations cause a malformation of the human brain.

AHS scientific conference to focus on impact of traumatic brain injuries

The impact of traumatic injuries to the brain - whether sustained in combat or on the playing fields of America's schools - is a major topic for international migraine specialists the week of June 18 as they gather in Los Angeles for the 54th Annual Scientific Sessions of the American Headache Society. This is among many timely issues concerning headache, migraine, and brain injuries on the four-day agenda here which runs through Sunday morning, June 24.

Distinct brain regions organize objects based on their physical size

The human brain can recognize thousands of different objects, but neuroscientists have long grappled with how the brain organizes object representation; in other words, how the brain perceives and identifies different objects. Now researchers at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) and the MIT Department of Brain and Cognitive Sciences have discovered that the brain organizes objects based on their physical size, with a specific region of the brain reserved for recognizing large objects and another reserved for small objects.

Concordia research helps develop first brain map of love and desire

Thanks to modern science, we know that love lives in the brain, not in the heart. But where in the brain is it - and is it in the same place as sexual desire? A recent international study is the first to draw an exact map of these intimately linked feelings.

Study identifies critical neurological factor in aggression

Pathological rage can be blocked in mice, researchers have found, suggesting potential new treatments for severe aggression, a widespread trait characterized by sudden violence, explosive outbursts and hostile overreactions to stress.

Study reveals critical aspect of how frontopolar cortex contributes to decision making

Researchers at the University of Iowa, together with colleagues from the California Institute of Technology and New York University, have discovered how a part of the brain helps predict future events from past experiences. The work sheds light on the function of the front-most part of the frontal lobe, known as the frontopolar cortex, an area of the cortex uniquely well developed in humans in comparison with apes and other primates.

MRI images of the brain when a person loses self-control

New pictures from the University of Iowa show what it looks like when a person runs out of patience and loses self-control.

A novel candidate gene in human early-onset degenerative ataxias

Researchers at the University of Helsinki and the Folkh-lsan Research Center, Finland, have identified the genetic cause of early-onset progressive cerebellar degeneration the Finnish Hound dog breed. The study, led by Professor Hannes Lohi, revealed a new disease mechanism in cerebellar degeneration. A mutation was identified in the SEL1L gene, which has no previous link to inherited cerebellar ataxias.

Acute levodopa may worsen motor plasticity in late-stage PD

Administering acute doses of levodopa appears to worsen motor cortex plasticity as Parkinson’s disease advances, researchers report.

IBMT linked with positive structural changes in brain connectivity

A Texas Tech University scientist studying the Chinese mindfulness meditation known as integrative body-mind training (IBMT) said he and other researchers have confirmed and expanded on changes in structural efficiency of white matter in the brain that can be related to positive behavioral changes in subjects practicing the technique for a month and a minimum of 11 hours total.

MIT engineers develop new glucose-powered implantable medical device

MIT engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose. This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed patients move their arms and legs again.

Researchers use brain imaging to uncover susceptibility to psychological stress and trauma

Most people have intense emotional reactions to traumatizing events like road accidents or combat. But some suffer far longer, caught in the grip of long-term debilitating disorders such as Post-Traumatic Stress Disorder (PTSD). Because doctors cannot predict who will develop these disorders, however, early or preventive intervention is not available. Now, a new project led by researchers at Tel Aviv University seeks to identify pre-traumatic subjects - those who are more susceptible to long-standing disorders if exposed to a traumatic incident.
