Your cerebrum makes up the bulk of your brain and has two parts, the left and right hemispheres. Both sides communicate with each other through the corpus callosum, a network of nerves. Each hemisphere of your brain controls the muscles and senses on the opposite side of your body. The left hemisphere is responsible for mental activities like logic, analysis, speech and language. Using the right side of your body stimulates the left-brain. Puzzles or games help sharpen the left side of your brain.
