Impact of video gaming on the brain

Wed, 2015-05-20 12:10

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.

Memory and Alzheimer’s: towards a better comprehension

Research by Dr. Sylvain Williams shows that the flow of activity in the hippocampus, a brain region essential for memory, is actually bidirectional, rather than just unidirectional

A study just published in the prestigious Nature Neuroscience journal by, Sylvain Williams, PhD, and his team, of the Research Centre of the Douglas Mental Health University Institute and McGill University, opens the door towards better understanding of the neural circuitry and dynamic mechanisms controlling memory as well of the role of an essential element of the hippocampus – a sub-region named the subiculum.
