HOW A BUG BRAIN WORKS

摘要

To investigate how insects detect and react to motion so quickly, neuroscientists at Howard Hughes Medical Institute examined the fruit fly. Turns out its brain, despite being several times smaller than a poppy seed, is astonishingly complex. After slicing just a small portion of the image-processing center into 2,000 pieces, the scientists constructed a connectome [right] out of the area's 379 neurons. They discovered it had 8,637 synaptic connections.
