Migraines and Seizures

The main parts of the human brain.

The cerebrum , in the forebrain, is by far the largest and most complex part of the brain. It is divided into two sides, the right and left hemispheres. The left hemisphere controls the right side of your body, and the right hemisphere controls the left side of your body. The two sides look similar, but they are not identical, and they do not necessarily serve the same functions. Both the cerebrum and the cerebellum are covered by the cerebral cortex, commonly known as “gray matter.” Besides its two hemispheres, the cerebrum is further divided into four lobes. The frontal lobes control your voluntary actions—the things you do on purpose, like walking around or picking up an object. They also help you consider different ideas, and decide how to behave in a situation. Behind the frontal lobes, the parietal lobes collect and process the data you pick up from your senses, including your sense of the space around you. They also help you read and do math. The occipital lobes manage and remember information coming from your eyes, while the temporal lobes do the same for the information coming from your ears.
