Gaming Can Train Your Intelligence

A new study has found that video gaming can stimulate neurogenesis (growth of new neurons) and connectivity in the brain regions responsible for spatial orientation, memory formation and strategic planning, as well as, fine motor skills.

Neurogenesis and neuroplasticity improvements were observed in the right hippocampus, right prefrontal cortex and the cerebellum. These brain regions are involved in functions such as spatial navigation, memory formation, strategic planning and fine motor skills of the hands. Increasingly, the level of connectivity between brain areas is being linked to higher intelligence and consciousness.

Gaming brings together the cerebral function of the cerebrum with the cerebellar muscle memory of the cerebellum which improves cognitive function and performance.

The benefits of video gaming could be helpful in therapeutic interventions targeting psychiatric disorders. Video games could be a useful tool for treating patients with mental health problems in which brain regions are altered or reduced in size.

Dr Brian Glass from Queen Mary's School of Biological and Chemical Sciences, said: "Previous research has demonstrated that Action video games, can speed up decision making but the current work finds that real-time strategy games can promote our ability to think on the fly and learn from past mistakes".
