Cerebrum (Forebrain)

    The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called “lobes”- the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
Frontal lobe: This is associated with reasoning, planning, parts of speech, movement, emotions, and problem solving.
Parietal lobe: This is associated with movement, orientation, recognition, perception of stimuli.
Occipital lobe: This is associated with visual processing.
Temporal lobe: This is associated with perception and recognition of auditory stimuli, memory, and speech.
   A deep furrow divides the cerebrum into two halves, known as the left and right hemispheres. The two hemispheres look mostly symmetrical yet it has been shown that each side functions slightly different than the other. Sometimes the right hemisphere is associated with creativity and the left hemispheres is associated with logic abilities. The corpus callosum is a bundle of axons which connects these two hemispheres. Nerve cells make up the gray surface of the cerebrum which is a little thicker than your thumb. White nerve fibers underneath carry signals between the nerve cells and other parts of the brain and body.
