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.

McGill Researchers Have Found A Fungal Toxin May One Day Repair Damage To The Central Nervous System

Injuries are a part of life. In most cases, such as cuts, bruises, tears, and even broken bones, our bodies heal. But when damage occurs to the central nervous system – or as most people call it, CNS – the outlook can be heartbreaking. The cells in this area, known as neurons, simply are not good at regeneration. This is why damage to the spinal cord and retina is considered a dire ailment.

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.

Molecule shown to repair damaged axons

Discovery could be key to treating brain and spinal cord injury

A foray into plant biology led one researcher to discover that a natural molecule can repair axons, the thread-like projections that carry electrical signals between cells. Axonal damage is the major culprit underlying disability in conditions such as spinal cord injury and stroke.

Andrew Kaplan, a PhD candidate at the Montreal Neurological Institute and Hospital of McGill University, was looking for a pharmacological approach to axon regeneration, with a focus on 14-3-3, a family of proteins with neuroprotective functions that have been under investigation in the laboratory of Dr. Alyson Fournier, professor of neurology and neurosurgery and senior author on the study.

Second study from UBC shows “liberation therapy” fails to treat multiple sclerosis

Opening up narrowed veins from the brain and spinal cord is not effective in treating multiple sclerosis (MS), according to a study led by the University of British Columbia and Vancouver Coastal Health.

The conclusions about so-called “liberation therapy,” which thousands of people with MS have undergone since 2009, represent the most definitive debunking of the claim that MS patients could achieve dramatic improvements from a one-time medical procedure.

Largest international study of its kind finds new schizophrenia risk genes

Results of the International Psychiatric Genomics Consortium unveiled

TORONTO – Canadian and international scientists have uncovered six new schizophrenia risk genes in the largest study of its kind. The results of the international Psychiatric Genomics Consortium CNV working group are published in the Nov. 21 advance online edition of Nature Genetics, and further support the important role genes play in susceptibility to schizophrenia, and may be helpful in early diagnosis.

UBC scientists create a mouse that resists cocaine’s lure

Shernaz BamjiScientists at the University of British Columbia have genetically engineered a mouse that does not become addicted to cocaine, adding to the evidence that habitual drug use is more a matter of genetics and biochemistry than just poor judgment.

The mice they created had higher levels of a protein called cadherin, which helps bind cells together. In the brain, cadherin helps strengthen synapses between neurons – the gaps that electrical impulses must traverse to bring about any action or function controlled by the brain, whether it’s breathing, walking, learning a new task or recalling a memory.

An eye-catching result

Research determines how the brain recognizes what’s important at first glance.

Researchers at the Centre for Neuroscience Studies (CNS) at Queen’s University have discovered that a region of the brain – the superior colliculus – contains a mechanism responsible for interpreting how visual input from a scene determines where we look. This mechanism, known as a visual salience map, allows the brain to quickly identify and act on the most important information in the visual field, and is a basic mechanism for our everyday vision.
