Researchers pinpoint a brain area that influences electoral decisions
Screening for genes whose risk association with breast cancer has yet to be proven is not justified and potentially harmful, argue an international team of leading geneticists and oncologists in a paper published this week in the prestigious New England Journal of Medicine.
A $1-million gift from Macdonald College of McGill University alumnus J. William Ritchie, BSc(Agr)'51, will provide major support for McGill’s Faculty of Agricultural and Environmental Sciences in its efforts to open its Macdonald campus to more visitors and provide a unique, hands-on education into the critical role of agriculture in the food supply chain.
A new study published in the journal Proceedings of the Royal Society B by the teams of Dr. Gregory West (Assistant Professor at the Université de Montréal) and Dr. Véronique Bohbot (Douglas Institute researcher and associate Professor at McGill University and the Douglas Research Institute of the CIUSSS de l’Ouest-de-l’Île de Montréal) shows that while video game players (VGPs) exhibit more efficient visual attention abilities, they are also much more likely to use navigation strategies that rely on the brain’s reward system (the caudate nucleus) and not the brain’s spatial memory system (the hippocampus). Past research has shown that people who use caudate nucleus-dependent navigation strategies have decreased grey matter and lower functional brain activity in the hippocampus.
With the arrival of spring, millions of Canadians have begun their annual ritual of sneezing and wheezing due to seasonal allergies.
