- The average human brain weighs about 1360 grams, or 3 lbs. That’s about four times lighter than an elephant brain. The heaviest mammalian brain is found in the sperm whale – weighing 7711 grams (17 lbs). Larger brains are needed, in part, to control larger muscles. At the other end of the scale is the owl brain that weighs just over two grams. A bullfrog's brain is about one-tenth smaller than that.

- 1. Three pounds, three parts. Your brain is your most powerful organ, yet weighs only about three pounds. It has a texture similar to firm jelly. It has three main parts: 1  The cerebrum fills up most of your skull. 2  The cerebellum sits at the back of your head, under the cerebrum. 3  The brain stem sits beneath your cerebrum in front of your cerebellum.

- The biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain's weight, and it's easy to see why. The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to. So you can't dance — or kick a soccer ball — without your cerebrum.

Brain size There is variation in child development in the size of different brain structures between individuals and genders. A human baby's brain at birth averages 369 cm 3 and increases, during the first year of life, to about 961 cm 3, after which the growth rate declines.Brain volume peaks at the age of 40, after which it begins declining at 5% per decade, speeding up around 70. human baby's brain at birth averages 369 cm 3 and increases, during the first year of life, to about 961 cm 3, after which the growth rate declines.

How Much Does the Human Head Weigh? The human brain weighs about three times more than a chimpanzee's brain and is four and a half times smaller than the brain of an elephant. Albert Einstein had a smaller than average brain that only weighed about 2.7 pounds, but it had more glial cells than average.

Number of Neurons in a Human Brain Differences in weight and size of a person's brain does not correlate with differences in mental ability. The adult human brain normally weighs from 1.0 to 1.5 kg (2¼ to 3¼ lbs). The work of the brain is similar to a combination of a computer and a chemical factory.

The Human Brain Physical Facts About the Brain. The adult human brain weights about 3 pounds and the cerebrum accounts for about 85% of the brain. The brain is composed of 40% gray and 60% white matter. The gray matter is made up of about 100 billion neurons that gather and transmit signals while the white matter is made of dendrites and axons that the neurons use to transmit signals. The brain is composted of about 75% water and is the fattiest organ in the body, consisting of a minimum of 60% fat. Humans have the largest brain to body ratio of any animal, and the blood vessels in the brain, if stretched end-to-end, would be about 100,000 miles long.

Brain The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex, which consists of gray matter. Beneath this lies the white matter. It's the cerebrum that makes the human brain—and therefore humans—so formidable.

Which Animal has the Largest Brain Largest brain by mass. The animal with the largest brain by weight is the sperm whale. The average full size sperm whale has a brain that is 9kg (about 20lbs). Although this is very big, it is only 0.02% of the total body mass of a sperm whale (the human brain is about 2% of our total body mass).

- On the other hand, some relatively “smart” animals have small brains – for example, dogs and orangutans: A beagle's brain is about 2.5 ounces, and an orangutan's brain is about 13 ounces. In general, the larger the animal, the larger the skull, and therefore, the larger the brain.
