Though the size of human brain is small it is a complex organ. The functions of the brain were found by the ancient Egyptians and Greeks in 400 BC. It was Hippocrates who first discovered that brain played an important role in sensation and intelligence. The research into the functioning of the brain gathered momentum from 0 AD to 1500 Ad. During this time period physicians began to recognize neurological disorders and treatments for the same. During this period, many surgical instruments were invented. Today, many researches are being conducted on various processes of the brain. There are many studies focused on disciplines such as neuroscience, cognitive science, behavioral science, psychology and so on. We look at a few interesting facts on the human brain.
A Few Neuro-Architecture Facts on the Human Brain
The central organ of the human body, brain, is anatomically divided into three parts called the forebrain, midbrain and the hindbrain. Here are a few interesting facts on the size and dimensions of the brain.
At the time of birth, the size of the brain is approximately 400gms and later as one becomes an adult, the size increases to approximately 1400gms. Another interesting fact is the height of an adult brain is 3.6 inches and the length is 6.3 inches. The width is 5.5 inches.
The cerebral cortex of the brain consisting of a frontal lobe, temporal lobe, occipital lobe and the parietal lobe occupies 85% of the human brain. The composition of the brain is 10-12% lipids, 8% protein, 77% water, 1% carbs, 2% soluble organics and 1% inorganic salt.
Half of the neurons in the brain reside in the cerebellum. But cerebellum occupies only 10% of the human brain.
Did you know that number of neurons in the human brain is equivalent to the total number of stars in our galaxy? That is 100 billion. There are 186 million more neurons in the left hemisphere of the brain than the right hemisphere.
Are you aware of the fact, approximately 1000ml of blood flows through the human brain every sixty seconds? In a minute the human brain absorbs 46 cubic centimeter of oxygen from the blood. Only 6% of the oxygen is used by the white matter of the brain while the gray matter absorbs 94%.
