A stroke in this area of the brain can lead to paralysis or “jerky” muscle movements. This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position. While the frontal lobe controls movement, the cerebellum “fine-tunes” this movement. The cerebellum is located behind the brain stem. This aspect of brain anatomy, makes clear why stroke symptoms often only affect one side of the body. The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. The cerebrum can be anatomically divided into two parts: the right and left hemispheres. Occipital lobe: processes visual stimuli.Parietal lobe: controls sensory comprehension, interpreting taste, touch, temperature, pain, movement and orientation.Temporal lobe: controls memory, hearing, and understanding of speech and allows a person to distinguish between sounds and smells.Frontal lobe: involved in motor function, problem solving, spontaneity, memory, language, initiation, judgment, impulse control, and social and sexual behavior.Each of these lobes has different functions, some of which may overlap. The cerebrum is the largest part of the brain, made up of four distinct lobes: the frontal, temporal, parietal and occipital. The signs and symptoms of a stroke depend on which region of the brain is affected and to what degree. To understand how stroke occurs and the damage it can cause, it is helpful to know the basic anatomy of the brain.
