Shown here is a depiction of a human brain beside a noticeably bigger elephant brain. The average human brain weighs in at around 3 pounds, and an elephant brain can weigh close to four times that much, but the biggest brains of all come sperm whales, and weigh an average of 17 pounds.
Together, the brain and the spinal cord form what is. known as the central nervous system. Though weighing in. at a mere 0.9 to 1.4 kilograms (about 2 to 3 pounds), the. human brain has an immense capacity to process, retain, and deliver information to the rest of the body.
