Brain Diagram and Cerebrum Function

The brain is the center of the nervous system.  The Nervous system has been regarded as the most complicated among all of the body systems. The brain has intrigued people especially healthcare professionals and scientists because of its undefined functions. An adult human has a brain weighing 1.5 kg forming the right and left hemisphere of the cerebrum. Until now, scientists still cannot determine why each hemisphere controls the opposite sides of the body wherein the left brain controls the right side of the body and the right controls the left. Have you seen the brain diagram yet or do you know the cerebrum function as well as its meaning?

The Cerebrum

Cerebrum, also known as telencephalon along with diencephalon is what organizes the forebrain. It is like the center of an organization that controls the functions of every department. The cerebrum function as the coordinator of the body responsible for directing the senses like hearing, vision, balance, smell, and taste. As the one controlling all the actions in vertebrates, the cerebrum contains billions of neurons connected to other neurons signalling the body to create actions.

Cerebrum Function

The cerebrum functions as the administrator for the decisions made by the body. The functions starts from the primary motor cortex as well as other area of the frontal lobe motor wherein actions are being planned. Aside from actions or movement, sensory processing is another cerebrum function. The cerebral cortex’s main sensory areas receive and process the information for auditory, visual, glustatory, olfactory and somatosensory. The relationship between the cortical areas, these regions of the brain makes the sensory information through the environment.

The cerebrum’s anterior portion in most vertebrates is called olfactory bulb. In humans however, this bulb is smaller and located below the frontal lobe. If this bulb gets damaged the sense of smell will be affected. Another function that the cerebrum processed is the language and communication. The language and the speech process of vertebrates especially for humans are associated within the frontal lobe and temporal-parietal lobe specifically the Broca’s and Wernicke’s area. Damage to Broca’s and Wernicke’s area may result to expressive aphasia and receptive aphasia respectively.

Another important cerebrum function concerns about memory and learning. The medial temporal lobe is the region associated to this function along with hippocampus. Damage or removal of hippocampus will eventually lead to amnesia which also prevents a person to form or have new memories.

Every part of the cerebrum in the brain diagram plays an important function. While people are still confused about the brain functions, they significantly made every possible brain diagram to illustrate how the center of the nervous system affects all body functions.  All of the body functions are associated with the cerebrum which is composed of the three sub-regions including cerebral cortex, basal ganglia, and the limbic system. According to all brain diagrams the cerebrum lies on the top or in front of the brainstem which is the largest among the five main divisions of human’s brain.
