How Do Insects Use Their Very Small Brains To Think Clearly?How do they engage in complex behaviour with only 100.000 to a million neurons?
If we had a skeleton that was outside, not inside, our body — and six legs — we might find it easier to understand how insects think. But only a bit easier. Despite complex behavior, insects are working with 100,000 to maybe a million neurons, compared to our, maybe, 86 billion — but insects make the most of what they have. Consider, for example, the dragonfly. How does it manage to deal with all the issues that a fighter pilot must address, while catching prey? One adaptation is specialized neurons: Dragonflies (order Odonata) and hoverflies (order Diptera) are among insect flyers equipped with special neurons for targeting with optic flow. “The ability of insects to successfully pursue targets in clutter Read More ›
