"The Intricate Design of the Human Brain"

  • The right hemisphere of a human brain weighs around three pounds or one and a half kilos, making up 2% of the body's weight but consuming 20% of the body's energy. It contains a hundred billion nerve cells or neurons, each with 10,000 connections, forming a brain network of a thousand trillion connections, more complex than any supercomputer. Despite its intricacy, the brain only has an electrical output of 20 Watts, enough to power a dim light bulb, showcasing its delicate and fragile nature. The frontal lobe serves as the command and control center, while the temporal lobe is responsible for language, emotion, and memory, highlighting the brain's intricate design and the vast unknowns that still exist in understanding its functions and dysfunctions.
