What hemisphere controls the right side of the body?
The reasons for this are not fully understood, but it is thought that because the left cerebral hemisphere of the brain controls the right side of the body, the right side is generally stronger; it is suggested that the left cerebral hemisphere is dominant over the right in most humans because in 90-92% of all humans, the left hemisphere is the language hemisphere.
What does the right frontal lobe of the brain do?
The right frontal lobe, on the other hand, is most associated with non-verbal abilities, creativity, imagination, musical, and art skills. The frontal lobe, like other structures of the brain, does not always work in isolation to each other. The frontal lobes work alongside other brain regions in order to control a variety of functions.

What is the cerebrum?
The cerebrum contains grey matter and billions of unmyelinated neurons (brain cells) called the cerebral cortex. Deeper parts of the cerebrum contain white matter, which is the collection of myelinated nerve fibers that connect different regions of the central nervous system (CNS) and spinal cord. Myelin sheath insulates and covers the neurons intermittently, helping to speed up nerve signals.
How many lobes does the cerebrum have?
The cerebrum is divided into four major lobes, each lobe with two halves, right and left. All four right halves come into the right hemisphere of the cerebrum and all four left halves come into the left hemisphere.
What are the folds of the cerebral cortex?
The cerebral cortex that is present superficially to the cerebrum is arranged in a folded manner and is only 2-4 millimeters thick. The folds on the cerebral cortex are called gyri, which are divided by grooves. The smaller grooves are called sulci and larger groves are called fissures. The fold of the sulci conceals about 66% of the brain's surface, with a total surface area of approximately 16 square feet. The cerebral cortex folds are the reason for the distinctive look of the brain.
Where is the occipital lobe?
Occipital lobe: Occipital lobe is in the backside of the upper brain below the occipital bone of the skull, behind the parietal and temporal lobes, and above the cerebellum. The central cerebral fissure divides the two occipital lobes, and a membrane called tentorium cerebelli separates it from the cerebellum. The occipital lobe is identified by the folds sulci and gyri. The occipital lobe is divided into four parts, each of which is responsible for a separate set of visual functions. Damage to the occipital lobe may lead to problems with vision.
Where is the parietal lobe located?
Parietal lobe: Parietal lobe is located behind the frontal lobe and above the temporal lobe, toward the upper area of the skull. The two parietal lobes are separated by the central sulcus. Temporal and parietal lobes are separated by the lateral sulcus, also called Sylvian fissure. The parietal lobe is a primary sensory area that interprets higher functions. It can perceive sensory information from outside the body, such as touch, pressure, pain, taste, and temperature. It helps the brain understand symbols, written and spoken linguistic issues, mathematical problems, codes, and riddles.
