University of Victoria Researchers Find A “Starburst” In The Space-Time Continuum of Motion Sensing

Most people take motion sensing for granted. Our eyes pick up on something moving and our brains are sent a signal to let us know something has occurred in our space-time continuum. Despite the simplicity of the task, the mechanisms allowing us this ability are incredibly complex. They have been studied for over fifty years and the neural circuitry underlying motion detection is probably the best described circuitry in the brain. Yet, researchers have not discovered all the answers.

Canadian Researchers Help To Understand How The Brain Copes With Stress

It’s one of the guarantees of life: stress. At its core, it’s a perception of a physical or psychological threat and is designed to help us survive. But the triggers are varied and as such, there is no single way to deal with the impending sensation of harm.
For years, researchers have studied the stress spectrum and identified numerous behavioural changes. Most are relatively simple to understand such as heightened awareness, risk avoidance, and the fight or flight response.

Canadian Researchers Reveal The Mental Trap of PTSD

Post-traumatic stress disorder (PTSD) is a scourge for anyone who suffers from it. The symptoms are heartbreaking – nightmares, flashbacks, poor sleep quality, irritability, and a lack of concentration. Some will feel disconnected from reality as they perceive being trapped in a mental cage from which they cannot break free.

Researchers Are Learning How The Brain Tells Us To Stop Moving

In the playground, a popular game for kids of all ages is “Freeze.” The concept is rather simple. A leader tells the participants they are free to move around until everyone is told to freeze in place. Those who don’t suddenly stop are notified they are out and the game continues. It’s a great way to learn how to deal with environmental stimuli and also how to better control locomotor abilities. But most of all, it’s a great deal of fun.

Quebec Researchers Are Learning How To Rebuild The Nervous System

Imagine repairing injured spinal cords or brains. Many may relegate this idea to the realms of science fiction yet researchers around the world continue to strive for this goal. They have developed and tested ways to rebuild the damage nervous system and bring back proper function. Some have even shown success in the lab.

A Novel Treatment May Help Reduce the Progression of Alzheimer’s Disease

Of all the neurodegenerative diseases, Alzheimer’s disease (AD) stands as the most common worldwide. While the onset is complex in nature, a hallmark sign of illness is the accumulation of a particular peptide in the brain, known as amyloid beta (Aβ) (http://www.jci.org/articles/view/25100). When present, the molecule can aggregate to form plaques and also interact with cells in the brain leading to altered signalling and function.
