How much brain power does a fly have?

They have about 200K brain cells, providing a baseline for their complex behaviors, say scientists who counted the bugs' cells.May 14, 2021


How complex is a fly brain?

Flies are capable of sophisticated behaviors, including navigating diverse landscapes, tussling with rivals and serenading potential mates. And their speck-size brains are tremendously complex, containing some 100,000 neurons and tens of millions of connections, or synapses, between them.Oct 27, 2021

Do all insects have brains?

  • Yes, insects do have a brain, though it doesn’t play the same role as a humans brain does. The insect brain consists of three lobes, each responsible for a different part on the body. Insects process sensory information using all three lobes, which are comprised of clusters of neurons.


Does fly have bones?

  • To achieve this, all flying birds have hollow bones, filled with pockets of air. The bones are held together by thin bar-like structures called struts. The struts prevent the bones from collapsing inward.
