Neuroscientists at the Flatiron Institute in New York City and their colleagues have made a big breakthrough using one of the world's smallest brains.
were first created 70 years ago, they were inspired by the knowledge of neurons in the brain," he says."But our knowledge has progressed significantly since then. Capabilities of the human brain exceed that of artificial intelligence, and we know that it is built by different rules, so there must be some secret sauce that biology has that can help us build better AI."
Studying the most basic brains in the animal kingdom makes it easier to identify the mechanisms and rules that govern complex behaviors, Chklovskii says. Theis an ideal subject for such a task. This microscopic wasp is only around 200 micrometers long, but it can fly and seek out the eggs of insects called thrips, in which the wasps lay their own eggs.
"A fruit fly is like an elephant compared to this," Chklovskii says."This whole creature fits into a fruit fly's eye." A specimen of Megaphragma viggianii, a parasitic wasp the size of some single-celled organisms such as amoebas. The tiny insect exhibits complex behaviors such as flight despite its small stature and brain, making it a useful tool for understanding how brains work. In a recent study, researchers at the Flatiron Institute and their colleagues mapped out the wasp's full early visual system.
