Impact of video gaming on the brain

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.
