The human brain is like a powerful computer that stores our memory and controls how we as humans think and react. It has evolved over time and features some incredibly intricate parts that scientists still struggle to understand. Let us find out more about it.

•    The brain is the centre of the human nervous system, controlling our thoughts, movements, memories and decisions.

•    The brain contains billions of nerve cells that send and receive information around the body.

•    The human brain is over three times as big as the brain of other mammals that are of similar body size.

•    Each side of the brain interacts largely with just one half of the body, but for reasons that are not yet fully understood, the interaction is with opposite sides, the right side of the brain interacts with the left side of the body, and vice versa.

•    The largest part of the human brain is called the cerebrum. Other important parts include corpus callosum, cerebral cortex, thalamus, cerebellum, hypothalamus, hippocampus and brain stem.

•    The brain of an adult human weighs around 3 pounds (1.5 kg). Although it makes up just two per cent of the body’s weight, it uses around 20 per cent of its energy.

•    The human brain is protected by the skull (cranium), a protective casing made up of 22 bones that are joined together.

•    The brain is suspended in Cerebrospinal fluid, effectively floating in liquid that acts as both a cushion to physical impact anda barrier to infections.— Compiled by The Surfer
