By observing the eye movements of schizo-phrenia patients while playing a simple video game, a University of British Columbia researcher has discovered a potential explanation for some of their symptoms, including difficulty with everyday tasks. Continue reading
There is no evidence that impaired blood flow or blockage in the veins of the neck or head is involved in multiple sclerosis, says a McMaster University study.
The research, published online by PLOS ONE Wednesday, found no evidence of abnormalities in the internal jugular or vertebral veins or in the deep cerebral veins of any of 100 patients with multiple sclerosis (MS) compared with 100 people who had no history of any neurological condition.

Findings identify a novel pharmaco-logical target for drug development
Researchers at McGill University have found that sodium – the main chemical component in table salt – is a unique “on/off” switch for a major neurotransmitter receptor in the brain. This receptor, known as the kainate receptor, is fundamental for normal brain function and is implicated in numerous diseases, such as epilepsy and neuropathic pain. Continue reading
New insight into how the brain communicates using a chemical messenger may lead to better understanding of memory preservation and may contribute to Alzheimer’s disease research.
Faculty of Medicine & Dentistry researchers Trevor Hamilton and Bill Colmers recently published findings in the Journal of Neuroscience Continue reading
Researchers at McMaster have discovered a solution to a long-standing medical mystery in Huntington’s disease (HD).
HD is a brain disease that can affect one in roughly 7,000 people in mid-life, causing an increasing loss of brain cells at the centre of the brain. Continue reading
New research is emphasizing the importance of regular screenings for glaucoma, a disease that deteriorates the optic nerve over time and is a leading cause of irreversible blindness worldwide. The onset of glaucoma is associated with a delay in diagnosing the disease. Continue reading
Medical researchers at the University of Alberta recently published findings showing that brain development is delayed throughout childhood and adolescence for people born with Fetal Alcohol Spectrum Disorder (FASD). Continue reading
Imagine being able to zoom into the brain to see various cells the way we zoom into Google maps of the world and can see houses on a street. And keep in mind that the brain is considered the most complex structure in the universe with 86 billion neurons. Zooming in is now possible thanks to a new brain atlas with unprecedented resolution. BigBrain is the first 3D microstructural model of the entire human brain, and is free and publicly available to researchers world-wide. Continue reading
Reducing levels of nerve-growth factor may be a key to developing better pain treatments
Arthritis is a debilitating disorder affecting one in 10 Canadians, with pain caused by inflammation and damage to joints. Yet the condition is poorly managed in most patients, since adequate treatments are lacking – and the therapies that do exist to ease arthritis pain often cause serious side effects, particularly when used long-term. Any hope for developing more-effective treatments for arthritis relies on understanding the processes driving this condition. Continue reading
Researchers at the University of British Columbia have developed a new magnetic resonance imaging (MRI) technique that detects the telltale signs of multiple sclerosis in finer detail than ever before – providing a more powerful tool for evaluating new treatments.
The technique analyzes the frequency of electro-magnetic waves collected by an MRI scanner, instead of the size of those waves. Although analyzing the number of waves per second had long been considered a more sensitive way of detecting changes in tissue structure, the math needed to create usable images had proved daunting.
