In what way is a human brain different from the brain of cockroaches and flies

Answer:
PLZ FOLLOW ME AND MARK MY ANS AS BRAINLIEST
Explanation:
There is, of course, good reason to view insect brains as primitive — at least quantitatively. Humans possess 100,000,000,000 brain cells. A cockroach has nearly 1,000,000 brain cells; a fruit fly, only 250,000. Still, insects exercise impressive information management: They pack neurons into their brains 10 times more densely than mammals do. They also use each brain cell more flexibly than mammals. Several far-flung tendrils of a single neuron can each act independently — boosting computing power without increasing the number of cells. Somehow that circuitry allows a honeybee, with barely a million neurons on board, to meander six miles from its hive, find food, and make a beeline directly home. Few humans could do the same even with a map and a compass.
