This essay example is presented by US Essay Writers.

Human brain is the most complex organ in the human body. Despite centuries of advancements in medical sign, the entire functionality of the human brain remains a mystery for medical experts as new types of neurons and brain functions are discovered every now and then. This essay focuses on the parts and functions of human brain in addition to the ongoing research on the newly discovered parts of the brain.

Although medical experts are aware of a large number of parts and functions of the brain, some astounding new discoveries are made after short intervals. For example, there is an ongoing research on ‘mirror neurons’ which have been termed as the part of the brain responsible for mirroring of actions and behaviors among humans and some other mammals. Researchers have highlighted the possibility that mirror neurons in human brain are responsible for development of human intelligence and therefore the civilization as we know it. Due to mirror neurons, humans were able to communicate using gestures which evolved into languages. With the rise of languages, humans started to develop and share knowledge which was used for development of the society. In light of the knowledge on human brain available to medical scientists, human brain can be divided into four main parts known as cerebral lobes, which are: frontal lobe, parietal lobe, temporal lobe and occipital lobe. The functions of frontal lobe include: controlling attention, intrapersonal thinking, ability to solve problems, and physical reactions. Thus, frontal lobe performs all the tasks that contribute towards the intelligence of the individual. These functions are extremely important as without these functions, an individual may not be able to think and therefore perform any of the day to day tasks. The parietal lobe is responsible for processing all the sensory information received by organs. The temporal lobe is responsible for controlling and retaining visual and auditory data in addition to language. Lastly, the occipital lobe is the smallest of all four cerebral lobes. This part of the brain is responsible for visual reception and processing, recognition of colors, and movement.

Thus, it can be concluded that human brain is a very complex organ which is responsible for multitude functions, and an unknown number of those functions is not yet known. There is still ongoing research on the composition and functions of brain. Each of the parts of the brain is responsible for some essential function without which the body will not be able to function normally. This attribute makes the brain the most essential part of the human body.
