Brain Facts

The human brain is one of the most powerful organs in the body. It allows us to think, store memories, analyze and make judgments while at the same time it controls other areas automatically, such as breathing. The human brain has been listed as the ‘original computer’ and has evolved over time in both size and complexity.

Most scientists still don’t understand how the brain works, although they understand small parts of it.

Fun Brain Facts for kids

  • The brain is the center of our nervous system, allowing us to control movements, thoughts and decisions.
  • The human brain has become more complicated with evolution, giving human beings abilities that are not available in other mammals.
  • There are billions of cells in the brain that send and receive information throughout the body.
  • Compared to other mammals of similar body size, the human brain is over three times larger.
  • The skull or cranium protects the brain and is made up of 22 bones that are all joined together.
  • When a baby is born, the upper part of the skull called the ‘sagittal suture’ is not fused or joined. This is to allow a baby the flexibility of birth. The area slowly fuses or closes with age.
  • The human brain only makes up about 2% of the weight of the body, it averages at around three pounds (1.5 kg) in an adult.
  • The brain is in constant use and needs about 20% of the energy as compared to the rest of the body.
  • Our brain is actually suspended in a protective fluid called the Cerebrospinal fluid. It acts as both a protection when we move around or due to impact as well as a barrier to keep infections out.
  • A stroke is where a blood clot has formed in the brain and it blocks the blood flow and supply to specific areas of the brain. This can cause damage to brain tissue and a number of symptoms to other areas of the body.

Each side of the brain acts both independently and together as well as controls one side or the other. Scientists don’t completely understand why each side controls the opposite side of the body. The left hemisphere of the brain controls the right side of the body and the right hemisphere of the brain controls the left side of the body.

The biggest part of the human brain is called the ‘cerebrum’. Other areas of the brain are: corpus callosum, thalamus, cerebral cortex, cerebellum, hippocampus, hypothalamus and the brain stem.

There are a number of diseases that can affect the brain. These can cause some or total limitations and can affect the brain as well as other parts of the body. Some of these diseases include: Parkinson’s disease, Alzheimer’s disease and multiple sclerosis.

Scientists have tried to study the brains of those people that were geniuses and passed away to see if there is anything specific that gave them their talents.

Einstein was one of the geniuses of the twentieth century. He approved for his brain to be removed after his death and used for study. Many sections of his brain were shared with scientific groups around the world.
