How are the cerebral hemispheres of the brain divided?
How are the cerebral hemispheres of the brain divided?
Cerebral Hemispheres. The cerebrum is divided into right and left hemispheres by the longitudinal fissure. The central sulcus separates the frontal lobe from the parietal lobe. The folds or convolutions in the brain are called gyri, the grooves are sulci.
Is the cerebrum in the right or left hemisphere?
Cerebral Hemispheres. The cerebrum is divided into right and left hemispheres by the longitudinal fissure. The central sulcus separates the frontal lobe from the parietal lobe.

What does the left cerebral hemisphere control?
The left cerebral hemisphere controls movement of the right side of the body. Depending on the severity, a stroke affecting the left cerebral hemisphere may result in functional loss or motor skill impairment of the right side of the body, and may also cause loss of speech.
Where is the right cerebral hemisphere located?
Cerebral hemisphere located on the right of the corpus callosum which controls the left side of the body. See also: hemispheric lateralization. RIGHT BRAIN: “The right brain is responsible for prosodic language functions.”.
What does the right side of the brain control?
The right side of the brain controls many of the body’s thought and actions. It focuses around judging the position of things in space, knowing body position, understanding and remembering things we do and see, putting bits of information together to make an entire picture, and it controls the left side of the body.
What does the right brain control?
Right hemisphere brain damage, or RHD, is damage to the right side of the brain. Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving . RHD may lead to problems with these important thinking skills.
