Insights on neural mechanisms behind guidance of attention

Ever wonder how the human brain, which is constantly bombarded with millions of pieces of visual information, can filter out what's unimportant and focus on what's most useful?

Study on relationship between pain and higher brain functions

University of Texas Medical Branch at Galveston professor Volker Neugebauer has been awarded a four-year, $1.36 million grant by the National Institute of Neurological Disorders and Stroke to conduct an innovative study of the relationship between pain and parts of the brain associated with cognitive thought and emotional response.

Study demonstrates how nerve stimulation paired with specific experiences can reorganize the brain

UT Dallas researchers recently demonstrated how nerve stimulation paired with specific experiences, such as movements or sounds, can reorganize the brain. This technology could lead to new treatments for stroke, tinnitus, autism and other disorders.

Impaired frontostriatal circuitry linked to cognitive defects in PD

Reduced activation of the frontostriatal circuits may underlie the mild cognitive impairment often seen in patients with early Parkinson’s disease, say researchers.

Micrographia prevalent in Parkinson’s

Around half of patients with Parkinson’s disease display symptoms of micrographia, a case–control study shows.

Diabetes linked to onset of Alzheimer's disease

Researchers from the University of Medicine and Dentistry of New Jersey (UMDNJ), collaborating with scientists from Northwestern University in Illinois, have provided direct experimental evidence that diabetes is linked to the onset of Alzheimer's disease.

BD II patients show altered brain activity during emotion processing

Depressed patients with bipolar II disorder show reduced activation and altered connectivity in brain regions associated with working memory and emotional learning, US researchers report.

Mobile Music Touch may improve motor skills, sensation for people with paralyzing SCI

Georgia Tech researchers have created a wireless, musical glove that may improve sensation and motor skills for people with paralyzing spinal cord injury (SCI).

Gait disturbances could indicate a decline in cognitive function

Gait disturbances – such as a slowing of walking pace or a more variable stride – could indicate a decline in cognitive function, according to new research studies reported today at the Alzheimer's Association's International Conference 2012 (AAIC 2012).

Memory-binding process allows people to better understand new concepts and make decisions

When humans learn, their brains relate new information with past experiences to derive new knowledge, according to psychology research from The University of Texas at Austin.

Combination of estrogen and MPA increases synapses in the prefrontal cortex

A new study of aged female rats found that long-term treatment with estrogen and a synthetic progesterone known as MPA increased levels of a protein marker of synapses in the prefrontal cortex, a brain region known to suffer significant losses in aging.

Dynorphin plays an important role in weakening anxiety

Feelings of anxiety very effectively prevent people from getting into situations that are too dangerous. Those who have had a terrible experience initially tend to avoid the place of tragedy out of fear. If no other oppressive situation arises, normally the symptoms of fear gradually subside.

Italy's first successful pregnancy and delivery following transplantation of ovarian tissue

Although the first successful preservation of fertility from the freezing, thawing and grafting of ovarian tissue was reported eight years ago, the technique has remained experimental and confined to a few specialist centres. Now, with the announcement of a first pregnancy (and subsequent live birth) in Italy following the transplantation of ovarian tissue, there are indications that fertility preservation is moving into the mainstream of reproductive medicine and into a greater number of centres.

Potential link between mutant huntingtin, cell loss and cell death in Huntington's disease

Using an in vitro cell model of Huntington's disease (HD), researchers at Florida Atlantic University's Charles E. Schmidt College of Medicine have discovered a novel mechanism and potential link between mutant huntingtin, cell loss and cell death or apoptosis in the brain, which is responsible for the devastating effects of this disease. Apoptosis has been proposed as one of the mechanisms leading to neuronal death in HD.

Transcranial direct current stimulation can enhance outcome of swallowing therapy for post-stroke dysphagia

After stroke, patients often suffer from dysphagia, a swallowing disorder that results in greater healthcare costs and higher rates of complications such as dehydration, malnutrition, and pneumonia.

Early brain changes predict chances of developing chronic pain

When people have similar injuries, why do some end up with chronic pain while others recover and are pain free? The first longitudinal brain imaging study to track participants with a new back injury has found the chronic pain is all in their heads -- quite literally.

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.
