Playing video games linked to enhanced brain connectivity and increased gray matter, research shows

The study by Macquarie University, published in Nature, explores the correlation between playing action video games and increased gray matter volume and brain connectivity. Using MRI scans, researchers studied 27 expert gamers and 30 amateurs, focusing on the insular cortex, a brain region involved in sensory, emotional, and cognitive functions. Results showed that expert gamers had superior brain connectivity and increased gray matter, likely due to the coordination of attention and sensory motor functions during gaming.

What was the main finding of the study conducted by Macquarie University?

• Action video games decrease brain connectivity.

• Playing action video games increases gray matter volume.

• Video games have no effect on the brain.

• Action video games reduce cognitive functions.

How many expert video game players were studied using MRI scans?

• 15

• 27

• 30

• 50

What is the role of the insular cortex in the brain?

• It is involved in memory storage.

• It controls only sensory functions.

• It acts as a hub linking various brain regions.

• It is responsible for motor skills only.

What did the study reveal about the brain connectivity of expert video game players?

• They have the same brain connectivity as amateurs.

• They have inferior brain connectivity.

• Their brain connectivity is unaffected.

• They have superior brain connectivity.

What might explain the increased gray matter volume in expert video game players?

• Lack of physical activity.

• Coordination between attention and sensory-motor functions.

• Increased screen time.

• Dietary habits.
