Cooperative play teaches turn-taking, fairness, and how to manage feelings with others.

Even beyond video games, playful activities help children process emotions, build resilience, and improve cognitive abilities. This early foundation is crucial for academic success and healthy relationships as children grow older.

The Brain on Play: Foundational Neuroscience

Every time you play—whether it’s kicking a ball or solving a video game puzzle—your brain is hard at work. These activities spark brain activity across several regions, engaging areas responsible for focus, memory, and problem-solving.

Modern neuroscience has revealed that play can boost the function and even the structure of certain brain regions. By measuring brain activity during playful tasks, scientists can see how different games and experiences light up areas of the brain that are vital for learning and growth.

How the Brain Processes Playful Activities

When you engage in playful activities, your brain lights up with activity. Cognitive scientists use tools like magnetic resonance imaging (MRI) to observe these changes. These technologies reveal which areas of the brain are most active during play and how they adapt over time.

Regular gameplay can change both the activity and structure of the brain. For instance, scientists have found that video games can increase the volume and activity of certain brain regions linked to attention, memory, and perception. As players get better at a game, their brains may use less energy for the same tasks, signaling greater efficiency in cognitive function.

The key neurological changes from regular gameplay include increased gray matter in regions responsible for spatial navigation, improved connectivity between brain regions, and more efficient information processing. “The brain is not set in stone. It can be changed over time by the things we do,” notes Dr. C. Shawn Green, highlighting the brain’s remarkable adaptability through play.

Key Brain Regions Activated During Play

Not all brain regions respond equally to play. During gaming or other playful experiences, regions like the hippocampus, prefrontal cortex, and cerebellum often show heightened activity. These areas are essential for memory, strategic thought, and motor skills.

MRI studies have found that regular gameplay can actually increase gray matter in these key regions. For example, puzzle games boost areas involved in planning and problem-solving, while action games stimulate regions linked to quick decisions and attention. This increase in gray matter is associated with sharper cognitive function and better brain development.

So, can playing games really sharpen memory, attention, and executive function? The answer is yes—by repeatedly exercising these skills through games, the brain becomes more efficient, making these cognitive abilities stronger over time.
