MRI reveals similarities between the human and chimpanzee brain

New MRI-based studies present more evidence that the brains of chimpanzees are human-like in terms of the relationships among brain asymmetry, handedness and language, according to research undertaken at the Yerkes National Primate Research Center in Atlanta.

Children with ADHD have abnormal fiber pathways in the frontal cortex

Children with attention deficit hyperactivity disorder (ADHD) display anatomical brain abnormalities beyond chemical imbalance, according to research presented at the annual meeting of the Radiological Society of North America (RSNA).

Transcranial Magnetic Stimulation to treat major depression

Psychiatrists at Rush University Medical Center are testing a noninvasive technique that uses repeated short bursts of magnetic energy to stimulate nerve cells in the brain to treat major depression.

Researchers find that alcohol has a profound effect on some, but not all, brain circuits activated in sober driving

New imaging studies from Yale show that when the human brain is under the influence of alcohol, different areas of the brain are impaired under high and low levels of alcohol.

An errant enzyme linked to bipolar disorder impairs awareness, perception and reasoning

The disturbed thinking, impaired judgment, impulsivity, and distractibility seen in mania, a destructive phase of bipolar disorder, may be traceable to overactivity of protein kinase C (PKC), suggests the study, funded by the National Institute of Mental Health (NIMH) and National Institute on Aging (NIA), and the Stanley Foundation.

Recovering alcoholics can remain sober for years

The study used a test that gauged participants' abilities to make sound choices between short-term rewards and the long-term negative consequences of their decisions.

Discovery of new method for visual impairment treatment

The patients suffering from visual impairment can be helped if a healthy donor’s cerebrospinal fluid is introduced to the parent’s vertebral canal – this method is called liquortransfusion.

Scientists are trying to determine what goes on inside the brain when it sees a face

Ever catch a glimpse of someone but can't quite fit a name to go with the face? While it's something that happens to everyone, for older people especially, difficulty in retrieving names is a common frustration.

Research speeds development of brain-controlled devices that may allow amputees and paraplegics to use their limbs

New research is speeding the development of brain-controlled devices that may soon allow amputees and paraplegics to use their limbs.

New direction for spinal cord research

A piece of the puzzle of how nerves find their way across the midline of the brain and spinal cord in a developing embryo has been found by Medical College of Georgia researchers.

Researchers have identified a protein in the brain that halts the progression of Alzheimer's

Researchers have identified a protein in the brain that halts the progression of Alzheimer's disease in human brain tissue. The protein, known as "transthyretin," protects brain cells from gradual deterioration by blocking another toxic protein that contributes to the disease process.

Men undergoing prostate cancer therapy forget things faster

Oregon Health & Science University researchers studying how testosterone deprivation affects verbal memory found that men undergoing the prostate cancer therapy forget things faster than their healthy counterparts.

Groundbreaking new study that may help stroke patients regain greater use of their hands or arms

The trial showed that study participants – stroke survivors suffering impaired hand or arm movement – who underwent physical rehabilitation accompanied by motor cortex stimulation showed greater improvement than participants who received physical rehabilitation alone.

Discovery of the gene for a form of Joubert Syndrome

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered the gene for a form of Joubert Syndrome, a condition present before birth that affects an area of the brain controlling balance and coordination in about 1 in 10,000 individuals.

Lack of improvement 24 hours after stroke treatment associated with poor outcome or death at 3 months

Stroke patients who show little improvement in the first 24 hours after receiving thrombolytic (clot-dissolving) therapy are more likely to have poor outcomes or death at three months, according to a study in the October 20 JAMA.

Research shows brain cells move like a two-stroke engine

Following the often-quoted advice of Yogi Berra — "You can observe a lot by just watching" — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.

Research findings represents a step toward understanding the machinery by which the brain processes decisions

While neurobiologists have long suspected that certain regions of the brain are specifically involved in making decisions, the challenge has been to develop rigorous laboratory behavioral experiments that could pinpoint those areas.

Brain imaging study shows brain differences between autistic boys with language impairment and those with normal language development

The study, published October 11, 2004, in the advance online issue of the Annals of Neurology, found that a language center of the brain -- Broca's area -- is apparently normal in autistic boys who have normal language capabilities.

Pilot study of mind-to-movement device shows early promise

In March 2002, Brown University researchers published an astounding piece of science. Three rhesus monkeys, they reported, could control a computer cursor without their hands. They used their minds instead.

Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence

Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence than do other children their age, according to two studies funded by the National Institutes of Health (NIH). Both studies appear in the October issue of Journal of Pediatrics.
