The most complex organ of the human body system is invariably the human brain. Unraveling the human brain’s been a long journey that still continues. Each day there’s a new discovery that is in addition to the unending functions of the human brain. The first people to draw the brain the commander and controller of the human body were the Greeks and the Egyptians of 4000 BC. It was Hippocrates, father of medicine who discovered that brain plays a role in sensation and intelligence. In 387 BC, Plato taught his pupils in Athens, that brain is here that the mental thought process takes place. Aristotle, claimed that it’s the human brain that’s the hand behind all the body actions and not the heart. This makes the ancient idiom ‘memorize by heart’ sound superficial. Soon, scholars of the 0 AD till 1500 AD confirmed that brain is the power behind the successful operation of the body.
After the ban on dissection of human body was lifted by the Church during Renaissance, great minds like Leonardo da Vinci and Rene Descartes began to take a look behind other minds and documented the information related to the elements of the brain. Let us have a look at the human brain diagram and learn a few facts about this ‘intelligent’ organ.
Investigating More About Human Brain
Before we have a look at the brain diagram, it’s important to go through a few facts about the brain and its function. This will help you understand the anatomy of the brain better.
The brain is composed of 77 to 78% water and 10 to 12% lipids. It contains 8% proteins 1% carbohydrates, 2% soluble organics and 1% insoluble salts. More than half of the neurons in the brain are located in the cerebellum and only 10% neurons make up the brain. 85% of the brain is cerebral cortex, divided as, 41% frontal lobe, 19% parietal lobe, 22% temporal lobe, and 18% occipital lobe. There are 186 million more neurons in the left hemisphere of the brain than the right hemisphere.
The human brain is an astonishing organ that takes care of each function and work of the body. All the functions are performed without a single glitch and before you even bat an eyelid. The following are the different regions of the human brain and their functions.
However, the human brain, as strong and as invincible as it may look, isn’t going to stay that way forever. The human brain will wither in the future, as with any other side of the body. One’s lifestyles and all other external factors will take toll against the human brain. As one grows old, the human brain will become slower in terms of functioning and rejuvenating itself. However, there are ways on how to enhance the strength of the human brain as age catches up. This article tries to give some useful advice on how to do just that.
The brain is part of the human anatomy. It is perhaps the most important organ in the body; but of course, we all know that every other organ in the body works for the others to function properly. The human brain is submitted to the lifestyle of the individual who owns it. If the person loves alcohol, he may not fully reap the faculties of his brain. Alcohol and other dangerous substances destroy brain cells. An alcoholic will argue that,’ I’ve been using only ten percent of my brain, drinking will activate the other 90% of it. ‘ This is a total fallacy. This premonition was made in the 1800s and there’s no truth in it. The brain is a lifetime organ, so we must maintain and protect it.
Eating the right sets of food will definitely benefit the brain. The brain is the more active part of the body. Even when one sleeps, the brain remains active and vibrant. The brain will welcome it if one eats the right and balanced sets of food. The sad is that the brain is commonly taken for granted when it is a question of having a balanced meal or a workout because people are so focused into developing their outside looks. It’s about time that we give the brain a break.
Proper exercise is well for the brain and not just for the body. The human brain needs a well-balanced life.
The central core consists of the thalamus, pons, cerebellum, reticular formation and medulla. These five regions are the central areas that regulate respiration, pulse, arousal, balance, sleep and initial stages of the processing sensory information. The thalamus interprets the sensory information and helps determine what’s good and bad. It then sends the message across the cerebral cortex to the region where further analyses of the information continues. The area that helps you dream and wake up from your sleep is the pons. The body coordination and control of posture and maintenance of equilibrium is taken care by the cerebellum. The signals transmitted to the cerebral cortex that helps in attending stimulation and remain alert while sleeping is taken care of by the reticular formation. Last but not the least, the medulla helps you breath, walk, sleep and signal the heart to continue beating.
The thalamus – This is the brain’s relay information network. It takes in sensory information and then passes those messages to the cerebral cortex.
The limbic system is present only in mammals and helps in the liaison between motivated behavior, emotional conditions and memory processes. The regions under the limbic system are hippocampus, amygdala and hypothalamus. The emotions, learning and memory actions are taken care of by the hippocampus and amygdala takes care of aggression, eating, drinking and the carnal instincts, that is, sexual behavior. On the other hand, hypothalamus looks after the blood glucose, salt, blood pressure and hormones. It regulates the body processes, as it is related to both the central and autonomic nervous systems and the endocrine systems.
This is the region that makes humans as humans. It is the region of higher cognitive and emotional functions. It is divided into two symmetrical halves called the cerebral hemispheres. Each individual hemisphere contains four lobes, occipital lobe, parietal lobe, the frontal lobe, and temporal lobe. The frontal lobe controls the actions like planning, decisions, setting goals and connects the present to future. The visual images are passed to the parietal and temporal lobes through the occipital lobe. The sensory processes, spatial interpretation, language, and attention comprehension is controlled by the parietal lobe. Lastly, language comprehension, the auditory perception, and visual recognition is controlled by the temporal lobe.
The brain acts as a center to receive, interpret and direct the information throughout the body. It is divided into three main divisions called the forebrain, midbrain and hindbrain. There are various areas and structures that make up these three division of the brain. Let us have a look at these areas and to know more about their functions.
The amygdala is situated deep within the limbic center in the same zone to which emotions are perceived. This structure is about the size of almond. It is in this region where emotional reactions like anger and fear are analyzed. It also controls the sexual urges. Recently, it was deemed to be associated with mental conditions such as autism as well as depression. It is bigger in size in males.
The cerebellum lies below the cerebrum. This region of the brain helps in balancing, movement, maintaining posture as well as muscle coordination.
The part of the brain that makes up the spinal cord is referred to as the brain stem. It helps the body survive by controlling the basic functions like breathing, digesting food, sleeping as well as heart rate.
The frontal lobe helps in organizing complex problems, helps plan steps to accomplish an objective, develops verbal skills, and participates in decision-making, problem solving and planning.
This region is placed deep within the brain and helps store memories for long-term. If this region was not present, people would be stuck with old memories and would never be in a position to develop or process new memories.
The hypothalamus is located at the root of the brain. This region helps in the hormonal system interact and maintain the degree of hormones in the body. It also helps maintain the blood pressure and temperature of the body as well as controls the sensation of appetite and body weight.
Homo sapiens understand the hidden brain powers, the dream of becoming super humans will turn into reality.
