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.
...A hypothetical rodent brain with 86 billion neurons, like the human brain, would be predicted to weigh an overwhelming 35 kg â a value that is way beyond the largest known brain mass [of any creature alive today].
