For the first time, scientists have imaged the entire brain of the fruit fly Drosophila melanogaster in enough detail to detect the individual junctions, or synapses, between every neuron. ... The 100,000-neuron fruit fly brain is elementary compared with the roughly 100 billion neurons in our own skulls.
