The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Overexpression of alpha-synuclein can cause Parkinson's

Researchers at the University of California, San Diego School of Medicine say overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons, starting with the terminal extensions of neurons and working its way back to the cells' center, with the potential consequence of progressive degeneration and eventual cell death.

Northwestern Medicine expert offers tips to battle seasonal affective disorder

Winter is in full force. With short days and less exposure to sunlight, everyone feels less energetic and more people are vulnerable to depression. Seasonal Affective Disorder (SAD), or winter depression, is a mood disorder related to seasonal variations of light. Symptoms start in late fall and oftentimes last until April or early spring. It affects between 10 to 20 percent of Americans, primarily younger adults and women.

Reprogrammed human skin cells highly effective in treating myelin disorders

A study out today in the journal Cell Stem Cell shows that human brain cells created by reprogramming skin cells are highly effective in treating myelin disorders, a family of diseases that includes multiple sclerosis and rare childhood disorders called pediatric leukodystrophies.

New data on attention and visual perception

The journal PLOS ONE has recently published a study which provides new data around attention and visual perception. The article "A role of eye vergence in covert attention" is signed by led by Hans Supèr, ICREA researcher at the Institute for Brain, Cognition and Behaviour (IR3C) of the University of Barcelona; Maria Solé Puig, J. Antonio Aznar Casanova and Laura Pérez Zapato, all of them researchers at the IR3C, have also participated in the study.

Broken motors induce stress and anxiety in mice

When motors break down, getting where you want to go becomes a struggle. Problems arise in much the same way for critical brain receptors when the molecular motors they depend on fail to operate. Now, researchers reporting in Cell Reports, a Cell Press publication, on February 7, have shown these broken motors induce stress and anxiety in mice. The discovery may point the way to new kinds of drugs to treat anxiety and other disorders.

Researchers develop special version of iDichotic for patients with schizophrenia

Two years ago, researcher Josef Bless was listening to music on his phone when he suddenly had an idea. "I noticed that the sounds of the different instruments were distributed differently between the ears, and it struck me that this was very similar to the tests we routinely use in our laboratory to measure brain function. In dichotic listening, each ear is presented with a different syllable at the same time and the listener has to say which syllable seems clearest. The test indicates which side of the brain is most active during language processing," Bless explains.

Drugs that target retromer pathway could help prevent or treat Parkinson's

Columbia University Medical Center (CUMC) researchers have identified a protein trafficking defect within brain cells that may underlie common non-familial forms of Parkinson's disease.

Nerve stimulator may be new option for migraine sufferers

Wearing a nerve stimulator for 20 minutes a day may be a new option for migraine sufferers, according to new research published in the February 6, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology.

New technique can detect mercury contamination in water

Chemists at the University of Burgos (Spain) have manufactured a sheet that changes colour in the presence of water contaminated with mercury. The results can be seen with the naked eye but when photographing the membrane with a mobile phone the concentration of this extremely toxic metal can be quantified.

Cedars-Sinai to include more patients in hypothermia plus clot-busting drug trial for stroke

An international multicenter clinical trial led by a Cedars-Sinai neurologist on the combination of brain cooling and "clot-busting" drug therapy after stroke has received Food and Drug Administration approval to expand from 50 patients to 400.

Basis of antidepressant drugs and electroconvulsive therapy found

Through a series of investigations in mice and humans, Johns Hopkins researchers have identified a protein that appears to be the target of both antidepressant drugs and electroconvulsive therapy. Results of their experiments explain how these therapies likely work to relieve depression by stimulating stem cells in the brain to grow and mature.

Migraine, epilepsy and genetics: an interview with Dr. Melodie Winawer

This work is the product of an extraordinary consortium called the Epilepsy Phenome/Genome project (EPGP). It is a consortium of 27 centres in the U.S. and internationally with several hundred physicians and staff who have worked together to enrol more than 4000 patients with epilepsy and their family members.

Study: 10 to 15% of people with TIAs will experience strokes within three months

Each year, as many as 500,000 Americans experience mini strokes called transient ischemic attacks (TIAs). Symptoms quickly go away, usually within an hour, and many people don't seek treatment. But 10 to 15 percent of people who experience TIAs will experience full-blown strokes within three months, and 40 percent of these strokes will occur in the first 24 hours, according to an article by three Loyola University Medical Center neurologists in the journal Expert Review of Neurotherapeutics.
