Human Brain: Facts & Functions

Human’s brain grows very fast. Immediately after birth, within 3 months of maturity it reaches half of the adult’s brain.

Using the advanced scanning techniques, scientists found that the male’s brain offspring grew much faster than that of women. Scientists made the distinction of that part of the brain that is related to evolve much faster gait, with the part that relates to evolve slower memory. Scientists say these new data may help them to identify the earliest signs of delayed development such as autism.

Led by a group of scientists from the University of California, researchers scanned the brains of 87 healthy infants from birth to 3 months. They found that the greatest changes occur immediately after birth. The newborn brain grow by an average of 1% per day.This development slows down to 0.4%  at the end of a 90 day period.

Scientists say that by recording normal growth trajectory of the individual parts of the brain may help to better understand how early disorders arise.They discovered that the Cerebellum, an area of the brain related to movement control, along 90 days, had faster growth, almost double compared to the rest of the brain.

Much of the challenge was the hippocampus, a structure that plays a very important role in terms of memory.

Regarding children born prematurely, scientists noticed that their brain was 4% lower than that of children born normally. Despite rapid growth, however, their brain was 2% lower at the end of 3 months. Now researchers will study closely to determine whether the consumption of alcohol and drugs during pregnancy affects brain size at birth.

These are just some of the vital functions of the human brain to perform, but the most amazing thing about the human brain is that many facts are less known by many people with a fully functional brain.human brain
The human brain is the only organ in the human body that has no nerves, despite the fact that he acts as central command for the central nervous system. This means that the human brain does not feel pain.
The human brain consumes the largest share of the total energy that is produced in the human body. To be more precise, the brain consumes 20% of energy, despite the fact that it represents only 2% of total body weight. Energy is vital to maintaining healthy brain cells.
The number of neurons present in the brain is approximately 100 billion, a figure 15 times higher than the general population on earth. This high number of neurons increases the ability of brain processing.
The human brain is calculated as fatty organ in the human body. About 60% of the human brain is composed of fat. Moreover, 75% of total brain mass is made up of water regulating various functions in the brain.
Neocortex is part of the human brain that is responsible for language and consciousness. It constitutes about 76% of the human brain.
Many people believe that human beings use less than 10% of their brain. This is a misconception, because every part of the brain has a known function.
During early pregnancy, neurons multiply at a rate of 250,000 neurons per minute.
About 15-20% 750ml of total cardiac output is directed to the brain every minute.
The energy consumed by the brain is enough to illuminate a light bulb, and
The human brain is not as perfect as thought.

While life expectancy in the world has increased, diseases that appear in ages past have become more frequent. This has led doctors and researchers find ways to treat or prevent diseases such as Parkinson’s, a brain injury that occurs after age 50, and is known for physical vibrations that causes the sufferer. Nowadays is achieved treated Parkinson’s symptoms, but scientists hope that very soon we will find a way to stop the progression of the disease.
