University of Calgary research study benefits people with severe essential tremor Elias Pharaon is 85 years old and can sign his name for the first time in five years thanks to a new way to do brain surgery. Performed by a team of University of Calgary physicians and researchers with the Hotchkiss Brain Institute, magnetic…

Pimozide, known for treating certain psychiatric conditions, may stabilize progression of the disease. The University of Calgary’s Lawrence Korngut is leading a clinical trial with nine hospital centres across Canada to recruit patients for further study. If you took part in the ALS Ice Bucket Challenge, you may have wondered where the money raised by the…

UCalgary researchers discover stress isn’t just contagious; it alters the brain on a cellular level In a new study in Nature Neuroscience, Jaideep Bains, PhD, and his team at the Cumming School of Medicine’s Hotchkiss Brain Institute (HBI), at the University of Calgary have discovered that stress transmitted from others can change the brain in the…

Treating people affected by Parkinson’s disease by grafting healthy neurons is an attractive idea which has not yet given the anticipated results up until now.  Even if grafted neurons survive, they are not able to recreate the dopaminergic neuron circuits that are essential for normal brain function.  An international team led by Martin Lévesque, professor…

A study by a group of researchers led by Alain Dagher from The Montreal Neurological Institute and Hospital of McGill University has tested the theory that brain degeneration in Parkinson’s disease (PD) originates in subcortical regions and spreads along neural networks to the cerebral cortex. By analyzing data on PD patients and healthy controls collected…

A discovery by Hideto Takahashi and his team paves the way for a better understanding of the mechanisms of neuropsychiatric disorders. Did you know? Your body is made up of a hundred billion nerve cells that, like small computers, receive, process and deliver crucial information to your body. These machines are your neurons. They form…

Volume in brain region linked to physiological changes characteristic of AD New research has drawn a link between changes in the brain’s anatomy and biomarkers that are known to appear at the earliest stages of Alzheimer’s disease (AD), findings that could one day provide a sensitive but non-invasive test for AD before cognitive symptoms appear.

A recent publication by Caroline Ménard shows that chronic stress, as occurs in cases of bullying, can make the blood-brain barrier more permeable to contaminants and microbes that may be in the blood.  As the brains of depressed individuals show signs of inflammation, Caroline Ménard and her colleagues had hypothesized that leakiness of the blood…

Learning and memory are crucial parts of human cognition, yet the biological processes that govern how we learn and store different types of memories are poorly understood. Although a cellular process called synaptic plasticity has long been thought to contribute to learning and memory, many of the neural mechanisms behind synaptic plasticity have remained unclear.…
