Scientists at Johns Hopkins Medicine are describing why insects are much smarter than what you would expect. After meticulously counting the neurons in fruit flies and three species of mosquitos, the experts found that their brains contained an average of 200,000 cells.
A human brain contains 86 billion neurons, while a rodent brain contains about 12 billion. According to the researchers, the average number of brain cells found in the insects likely represents a “floor” for the number needed to execute complex tasks.
“Even though these brains are simple (in contrast to mammalian brains), they can do a lot of processing, even more than a supercomputer,” said Dr. Christopher Potter.
