WeiQi (right) vs. Chess (left)

I found this 2002 Functional MRI study comparing the brains of Go players vs Chess Players. Seems that when playing Go the brain tends to lateralize (even if modestly) to the right brain parietal lobe while it tends to lateralize to the left brain when playing Chess. Here are the functions of those lobes which can be seen when those parts are damaged.

Right (GO)

• Non-verbal memory
• Drawing Memory
• Space Awareness
• Construction Skill

Left (Chess)

• Verbal Memory
• Recall of List of digits
• Right-Left Confusion
• Writing Ability
