What is the Cerebrum?

The cerebrum is a large portion of the brain that controls our motor activities. Half of our brainstem neurons are located here. It is located at the top of our skull in the cranial cavity. To guide our actions, the cerebrum and cerebellum work together.

Many blood vessels are found in the cerebrum. Two main blood vessels supply blood to the brain. They connect with each other through the foramen of Monro and aqueduct of Sylvius, and they drain into the internal jugular veins. The internal carotid artery supplies most of the cerebrum with blood.

The cerebrum can be divided into two halves, which are connected partially by the corpus callosum. The two hemispheres are connected by long, thin nerve fibers known as axons. The cerebrum is home to approximately 70 billion neurons. It is one of the largest areas of the brain. The white matter is made up of long nerve fibers connecting different parts of the brain.

The cerebrum is composed of three kinds of functional areas. One part is the cerebral cortex, which controls all of our intellect, cognition, memory, and personality. Another part is the basal nuclei, which regulates motor activities. Finally, the cortex contains a portion that is responsible for bursting the lungs and sensation of fullness in the bladder.

The cerebrum is the brain’s outermost region. Its gray matter can be labeled with a color. It consists of four lobes, the frontal lobe processes problem solving, the parietal lobe processes sensory inputs, the temporal lobe processes auditory information, and the occipital lobe handles movement. These lobes all work together to control voluntary behaviors.

The cerebrum is enclosed by the frontal and intraparietal operculums, the frontal lobes, and the frontal operculum. The frontal lobe contains the choroid plexus and the tela choroidea, and the middle frontal gyrus.

The deeper regions of the cerebrum contain the hippocampus, the basal ganglia, and the olfactory bulb. The hippocampus, named after a Greek word meaning “seahorse,” is a large, hollow region of the brain that plays an important role in long-term memory. The hippocampus consists of the hippocampus proper and the dentate gyrus, which is one of the brain’s two sites for neurogenesis.
