The Cerebral Cortex

Your fists represent the cerebral cortex, the most complex area of your
brain. Notice how it is divided into two equal half balls, or spheres, called
hemispheres. The left hemisphere is dedicated to processing information
logically in a step-by-step manner. For example, it helps you read, speak, and
write language or compute an equation. The right hemisphere is responsible for
more processing of spatial information, such as recognizing a friend's face, or
appreciating a piece of artwork. Quite simply, your left hemisphere sees the
"trees" (details), while your right hemisphere sees the "forest" (big
picture).
