Opioids, such as morphine and fentanyl, are powerful drugs used to manage a variety of pain conditions. However, chronic opioid use can result in the development of physical dependence. When individuals stop opioid use, they may suffer from a debilitating withdrawal syndrome. Continue reading →

Of all psychiatric conditions, obsessive-compulsive disorder, or OCD as it’s more commonly known, is perhaps the most widely known and also, misunderstood. Colloquially, this term is used to describe anyone with a penchant for a obsessive nature. Yet, this ailment, which only affects about 2% of the population, is quite difficult to both diagnose and manage. Continue reading →

Recent events at home and abroad foreshadow a more divided and closed world.  As such, the Canadian Association for Neuroscience wants to state their position that science can and must remain a builder of bridges between the peoples of all nations, regardless of differences in political views, religious beliefs or country of origin. Scientists around the world share a desire to advance knowledge in ways that benefit all humans. Continue reading →

Imagine a fender bender at an intersection. It’s a common occurrence and, usually, someone is at fault. But ask any police officer and you’ll find the blame may not be all that easy to determine. The stories from the drivers involved often oppose one another and eye-witness reports also may reveal striking differences in how the accident unfolded. Continue reading →

“The most terrible poverty is loneliness, and the feeling of being unloved.”
-Mother Teresa

At one time or another, everyone experiences moments of social isolation, when there is no one around and the world is confined to one’s own existence. In short bursts these moments of solitude can be therapeutic and may lead to moments of emotional regeneration or creativity. Yet when loneliness becomes chronic, the effects may be deleterious to one’s emotional health. Continue reading →

Alzheimer’s disease is growing in Canada at an unprecedented rate. At the moment, over half a million people suffer from this debilitating condition but that number is expected to nearly double over the next generation. The effects of this illness are tragic, such as memory loss as well as changes in behaviour, judgement, and normal daily function. For this reason, understanding this disease and finding meaningful treatments are considered a priority.
As Alzheimer’s progresses, a protein, known as amyloid-β, begins to clump together, forming what is officially called a plaque. As this happens, the neurological landscape changes as neurons begin to die off. Despite decades of research, the mechanism behind this loss remains, for the most part, a mystery. Continue reading →

If you happen to watch any survival-based reality series, such as the Canadian Survivorman series, you’ll come to realize starvation has a dire effect on the body. A person becomes weak, disoriented, and begins to crave protein. In humans,  this is considered to be normal as we are considered omnivores. Yet, this effect also can be seen in other species, including one usually considered to be herbivorous.
The common fruit fly, Drosophila melanogaster, primarily feeds, as the name implies, on decaying fruit and the microorganisms inhabiting it Yet, when this insect undergoes starvation, its tastes change. After several days with no food, they turn carnivorous and even cannibalistic.  This dramatic change in food choice, while observed, still has yet to be fully understood. Continue reading →

Have you ever noticed a tendency to drink some water or other liquid sustenance right before going to bed? It’s a common occurrence although the reason behind this action has not been well understood. This unfortunately has led to a rather large-scale debate regarding the potential health benefits and risks of having a swig before sleep.
Over the years, some researchers have suggested the action is based on a physiological need, such as elevated body temperature or low water concentration in blood. Others have suggested this action is psychological rather than biological in nature as it increases the chances for REM sleep and dreaming. Then there are those who feel this action has no health value at all. After all, drinking immediately before sleep means you will no doubt have to disturb your regular period of rest for a quick bathroom break. Continue reading →

Imagine losing the ability to control your nerve function. You may encounter numbness and weakness in the limbs. Your ability to speak could decline as well as your vision. Tics and tremors might take over certain parts of your body. You even are at risk for depression.
These are just a few of the symptoms of multiple sclerosis, which is better known simply as MS. This condition affects over two million people worldwide and leads to significant reductions in a person’s quality of life. Yet quite possibly the worst aspect of this disease isn’t the range of symptoms, but the culprit causing them. Continue reading →

What convinces a stem cell to determine its fate? It’s one of the most persistent questions in modern biology. Research over the last four decades has revealed there is no easy answer. For example, in the brain, stem cells in the embryo produce all of the different cell types at precise times and amounts. If stem cells are perturbed by altering their ability to make those cell types, this is thought to contribute to neuropsychiatric and developmental disorders.
To produce their progeny, stem cells receive signals from other cell types, blood vessels, and the cerebral spinal fluid, and even produce signals themselves. This in itself raises numerous questions. What are those signals? How many are there? How does a stem cell decide to respond to one signal and not another? More importantly, how can this all happen in a coordinated manner to ensure the proper development of the brain? Continue reading →
