The Canadian Association for Neuroscience applauds the announcement by the Canadian government of important new financial support for Investigator-led fundamental research. This budget makes significant strides towards the implementation of the recommendations of the Fundamental Science Review, commissioned by the honourable Kirsty Duncan, Minister of Science, and is good news for scientists across the country, and all Canadians.

Making information meaningful leads to better memory
When trying to memorize information, it is better to relate it to something meaningful rather than repeat it again and again to make it stick, according to a recent Baycrest study published in NeuroImage.
“When we are learning new information, our brain has two different ways to remember the material for a short period of time, either by mentally rehearsing the sounds of the words or thinking about the meaning of the words,” says Dr. Jed Meltzer Continue reading
Sick Kids Researchers Have Found An Unexpected Twist in How Our Brains Develop
One example of the latter recently came from the joint laboratory of Freda Miller and David Kaplan, at the Hospital for Sick Children in Toronto. They found that a type of cell known for transmitting information between nerve cells also plays another vital role. It instructs stem cells that build the brain to make another type of cell called an oligodendrocyte. This cell is crucial for making sure communication and information transmission in the brain happen at the right time in the right place. The results were published in the journal, Neuron, http://www.cell.com/neuron/fulltext/S0896-6273(17)30344-6. Continue reading
McGill Researchers Have Found A Possible Path For Treatment of Fragile X Syndrome
There is no denying autism spectrum disorders, commonly known as ASD, have become some of the world’s greatest health concerns. But what most people do not know is the incredible complexity of these conditions. As researchers have found, the problems are not singular in nature. Rather, they are a consequence of several changes in the way the cells of the brain function. This reality has forced ASD researchers to head deep into the molecular level of the brain in the hope of understanding what is happening in those affected.
Brain area involved in addiction activated earlier than previously thought in recreational cocaine users
Non-dependent users also experience dopamine release in response to drug cues
Even among non-dependent cocaine users, cues associated with consumption of the drug lead to dopamine release in an area of the brain thought to promote compulsive use, according to researchers at McGill University.
The findings, published in Scientific Reports, suggest that people who consider themselves recreational users could be further along the road to addiction than they might have realized. Continue reading
Common acne medication offers new treatment for multiple sclerosis – Study results offer safe and affordable treatment option
A Canadian clinical trial led by researchers at the University of Calgary’s Hotchkiss Brain Institute (HBI), at the Cumming School of Medicine (CSM), shows that minocycline, a common acne medication, can slow the progress of relapsing-remitting multiple sclerosis (MS) in people who have recently experienced their first symptoms.
In addition to being an unexpected discovery — an acne drug benefitting a neurological disorder — the discovery is significant as it offers a safe and affordable treatment option for those with early onset MS. This discovery could impact thousands of newly diagnosed MS patients around the world. Continue reading
Researchers identify specific neurons that distinguish between reality and imagination
New Western University research shows that neurons in the part of the brain found to be abnormal in psychosis are also important in helping people distinguish between reality and imagination.
The researchers, Dr. Julio Martinez-Trujillo, principal investigator and professor at Western University’s Schulich School of Medicine & Dentistry and Dr. Diego Mendoza-Halliday, postdoctoral researcher at M.I.T., investigated how the brain codes visual information in reality versus abstract information in our working memory and how those differences are distributed across neurons in the lateral prefrontal cortex region of the brain. The results were published today in Nature Communications (https://www.nature.com/articles/ncomms15471) Continue reading
Researchers identify a new factor essential for the healthy development of a child’s brain
Proper brain development is a crucial step in a child’s health. An important part of brain development is the creation of white matter, which enables different regions of the brain to rapidly and effectively “talk” to one another.
In a new study published in Neuron, a team of researchers led by Dr. Freda Miller and Dr. David Kaplan has revealed how oligodendrocytes, which are crucial for proper brain function and that are damaged or altered in conditions such as Multiple Sclerosis, autism and concussions, are formed during development.

University of Ottawa Researchers Have Found Yet Another Benefit From Exercise
No one can argue against exercise being good for you. Decades of research have revealed how getting our bodies in motion can offer a wealth of health benefits. Our muscles, metabolism, and immunity all improve as well as our brains. Our ability to learn and remember gets better and we may be able to ward off diseases such as Alzheimer’s disease and multiple sclerosis . Continue reading
Researchers at Dalhousie University Reveal A Startling Phenomenon in Evolution
Have you ever been startled by a sudden noise, sight or touch? It can be quite a shock to the system. You tense up, your mind blanks out all previous thoughts, and you find yourself preparing for the worst. Then there are the lingering effects that can last for minutes after it is all over. While you may hate the feeling of being startled, neuroscience researchers have found the entire process is a natural part of life inherited in evolution from our ancient ancestors. Continue reading
