Reasoning and behavioral control dependent on different regions of frontal lobes

The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes-which are located just behind and above the eyes-can result in profound impairments in higher-level reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at the California Institute of Technology (Caltech) recently teamed up with researchers at the world's largest registry of brain-lesion patients.

Study identifies how genetic mutations in the nervous system cause Duane Syndrome

A research team from King's College London and the University of Exeter Medical School has identified how a genetic mutation acts during the development of nerves responsible for controlling eye muscles, resulting in movement disorders such as Duane Syndrome, a form of squint.

Chemists develop new lab test to examine how DNA damage disrupts protein synthesis

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.

Scientists unravel how brain cells encode pronunciation of individual vowels in speech

Diagnosed with Lou Gehrig's disease at 21, British physicist Stephen Hawking, now 70, relies on a computerized device to speak. Engineers are investigating the use of brainwaves to create a new form of communication for Hawking and other people suffering from paralysis. -Daily Mail

GM-CSF depletion suppresses pain in people with arthritis-related conditions

The research relates to a family of molecules firstly discovered in Melbourne that applied to blood cell development. One of these, granulocyte macrophage colony-stimulating factor or GM-CSF, acts as a messenger between cells acting at a site of inflammation.

Investigators discover biological explanation for why low levels of oxygen advance SMA symptoms

Investigators at Nationwide Children's Hospital may have discovered a biological explanation for why low levels of oxygen advance spinal muscular atrophy (SMA) symptoms and why breathing treatments help SMA patients live longer. The findings appear in Human Molecular Genetics.

Study highlights Nek9 protein as decisive factor in cell division

A study by the Institute for Research in Biomedicine (IRB Barcelona) and the Center for Genomic Regulation (acronym in Catalan CRG) highlights the protein Nek9 as a decisive factor in cell division, a fundamental process for both the development of an organism and tissue maintenance.

New silicon chips help identify patients with lupus

Researchers at the Stanford University School of Medicine and Intel Corp. have collaborated to synthesize and study a grid-like array of short pieces of a disease-associated protein on silicon chips normally used in computer microprocessors.

Neurally-interfaced hand prosthesis re-establishes communication between nervous systems

Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves.

FSH-specific polyclonal antibody might offer more effective way to prevent osteoporosis

A new study suggests that a polyclonal antibody that blocks follicle-stimulating hormone (FSH) in mice without ovaries might offer a more effective way to prevent or arrest osteoporosis than currently available treatments.

Berry wines may help people with diabetes decrease their blood sugar

In evaluating the bioactive compounds of Illinois blueberry and blackberry wines, University of Illinois scientists have found compounds that inhibit enzymes responsible for carbohydrate absorption and assimilation. And that could mean a tasty way to help people with diabetes decrease their blood sugar.

Methyl-glyoxal could play a major role in abdominal obesity, insulin resistance and type 2 diabetes

Researchers at Mount Sinai School of Medicine have identified a common compound in the modern diet that could play a major role in the development of abdominal obesity, insulin resistance, and type 2 diabetes.

MitoTarget Project and neurodegenerative diseases: an interview with Rebecca Pruss, Ph.D., CSO of Trophos

The MitoTarget Project was a project funded by the European Commission, under their FP7 programme. It was funding for a call published in 2007.

Study demonstrates MRI role in defining and understanding causes of MS

New magnetic resonance imaging (MRI) research shows that changes in brain blood flow associated with vein abnormalities are not specific for multiple sclerosis (MS) and do not contribute to its severity, despite what some researchers have speculated. Results of the research are published online in the journal Radiology.

National Jewish Health, BWH to receive NHLBI grant for second phase of COPDGene project

The COPD Foundation (COPDF) recently announced that the National Heart, Lung, and Blood Institute (NHLBI) will fund the second phase (2012-2017) of the COPDGene project as R01 grants to National Jewish Health and the Brigham and Women's Hospital.

Study identifies mode of death of cone photoreceptor cells in animal model of RP

Research conducted at the Angiogenesis Laboratory at Massachusetts Eye and Ear Infirmary, has for the first time, identified the mode of death of cone photoreceptor cells in an animal model of retinitis pigmentosa (RP).

Platelet-like nanoparticles nearly double survival rate after internal injury

Nanoparticles tailored to latch onto blood platelets rapidly create healthy clots and nearly double the survival rate in the vital first hour after injury, new research shows.

Muscle synergies activated in altered ways after stroke

The simple act of picking up a pencil requires the coordination of dozens of muscles: The eyes and head must turn toward the object as the hand reaches forward and the fingers grasp it. To make this job more manageable, the brain's motor cortex has implemented a system of shortcuts. Instead of controlling each muscle independently, the cortex is believed to activate muscles in groups, known as "muscle synergies." These synergies can be combined in different ways to achieve a wide range of movements.

Dogs offer excellent animal model for human obsessive compulsive disorder study

The genetics research group, based at the University of Helsinki and the Folkh-lsan Research Center and led by Professor Hannes Lohi, has in collaboration with an international group of researchers investigated the characteristics and environmental factors associated with compulsive tail chasing in dogs.

Study utilizes integrative approach to probe biology of bipolar disorder

The more that we understand the brain, the more complex it becomes. The same can be said about the genetics and neurobiology of psychiatric disorders. For "Mendelian" disorders, like Huntington disease, mutation of a single gene predictably produces a single clinical disorder, following relatively simple genetic principals. Compared to Mendelian disorders, understanding bipolar disorder has been extremely challenging. Its biology is not well understood and its genetics are complex.
