That's the finding of a new Canadian study by Université de Montréal psychology professors Gregory West, Sylvie Belleville and Isabelle Peretz. Published in PLOS ONE, it was done in cooperation with the Institut universitaire de gériatrie de Montréal (IUGM), Benjamin Rich Zendel of Memorial University in Newfoundland, and Véronique Bohbot of Montreal's Douglas Hospital Research Centre.
In two separate studies, in 2014 and 2017, young adults in their twenties were asked to play 3D video games of logic and puzzles on platforms like Super Mario 64. Findings showed that the gray matter in their hippocampus increased after training.
Hippocampus - Region - Brain - Memory - Factor
The hippocampus is the region of the brain primarily associated with spatial and episodic memory, a key factor in long-term cognitive health. The gray matter it contains acts as a marker for neurological disorders that can occur over time, including mild cognitive impairment and Alzheimer's.
West and his colleagues wanted to see if the results could be replicated among healthy seniors.
Research - Team - People - Groups - Participants
The research team recruited 33 people, ages 55 to 75, who were randomly assigned to three separate groups. Participants were instructed to play Super Mario 64 for 30 minutes a day, five days a week, take piano lessons (for the first time in their life) with the same frequency and in the same sequence, or not perform any particular task.
The experiment lasted six months and was conducted in the participants' homes, where the consoles and pianos, provided by West's team, were installed.
Researchers - Effects - Experiment - Beginning - End
The researchers evaluated the effects of the experiment at the beginning and at the end of the exercise, six months later, using two different measurements: cognitive performance tests and magnetic resonance imaging (MRI) to measure variations in...
