Brain

Uncovering the secrets of the brain requires an intense network of collaborative research. Building on a tool that was co-developed in his laboratory and described in a recent issue of Brain, Dr. Yaniv Assaf of Tel Aviv University's Department of Neurobiology is collaborating with an international team of scientists to understand how different parts of the human brain "connect" -- and to turn this information into a "brain atlas."

Patients with early-stage schizophrenia who receive a combination of medication and a psychosocial intervention appear less likely to discontinue treatment or relapse—and may have improved insight, quality of life and social functioning—than those taking medication alone, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Using a moving 3D computer model based on the skull and teeth of a New Zealand reptile called tuatara, a BBSRC-funded team from the University of Hull, University College London and the Hull York Medical School has revealed how damage to dental implants and jaw joints may be prevented by sophisticated interplay between our jaws, muscles and brain. This research will appear in a future edition of the Journal of Biomechanics.

A new study from Sweden's Karolinska Institutet suggests that bipolar disorder – or manic-depressive disorder – does not increase the risk of committing violent crime. Instead, the over-representation of individuals with bipolar disorder in violent crime statistics is almost entirely attributable to concurrent substance abuse.

UPTON, NY — A brain-scanning study at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, conducted with collaborators from Stony Brook University, reveals that an oral dose of methylphenidate, commonly known as Ritalin, improves impaired brain function and enhances cognitive performance in people who are addicted to cocaine.

Stockholm, 6 September, 2010 - Inflammation is associated with lower intelligence and premature death, according to Swedish scientists from the Karolinska Institute in Stockholm, Sweden. "Those with low-grade inflammation performed more poorly on standardised intelligence tests, even after excluding those with signs of current illness. Inflammation also predicted an increased risk of premature death," said lead researcher Dr Hakan Karlsson.

Cockroaches could be more of a health benefit than a health hazard according to scientists from The University of Nottingham.

Experts from the School of Veterinary Medicine and Science have discovered powerful antibiotic properties in the brains of cockroaches and locusts which could lead to novel treatments for multi-drug resistant bacterial infections. They found that the tissues of the brain and nervous system of the insects were able to kill more than 90 per cent of MRSA and pathogenic Escherichia coli, without harming human cells.

New device lets paralyzed people speak with their brains

SALT LAKE CITY, Sept. 7, 2010 – In an early step toward letting severely paralyzed people speak with their thoughts, University of Utah researchers translated brain signals into words using two grids of 16 microelectrodes implanted beneath the skull but atop the brain.

Cockroaches could be more of a health benefit than a health hazard according to scientists from the University of Nottingham, who have discovered powerful antibiotic properties in the brains of cockroaches and locusts.

Simon Lee, a postgraduate researcher who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham, describes how the group identified up to nine different molecules in the insect tissues that were toxic to bacteria. These substances could lead to novel treatments for multi-drug resistant bacterial infections.

ST. PAUL, Minn. –A new study shows that mild cognitive impairment (MCI) may affect more men than women. The research is published in the September 7, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Mild cognitive impairment is a condition in which people have problems with memory or thinking beyond that explained by the normal rate of aging. The study found that MCI was 1.5 times higher in men compared to women. MCI often leads to Alzheimer's disease.

ROCHESTER, Minn. -- A new Mayo Clinic study found that the prevalence of mild cognitive impairment was 1.5 times higher in men than in women. The research, part of the Mayo Clinic Study of Aging, also showed a prevalence rate of 16 percent in the population-based study of individuals aged 70-89 without dementia who live in Olmsted County, Minn. The study will be published in the September issue of Neurology.

A fixation on geometric patterns may be associated with autism in children as young as 14 months, according to a report published online today that will appear in the January 2011 print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
