Neurons in the visual system of flies exhibit surprisingly heterogeneous wiring, connectome analysis finds

The brain is a particularly complex organ, not only in humans. Even the brain of a fly contains more than 100,000 neurons connected by millions of synapses. For the first time, an international community of researchers has reconstructed and published all neurons with their corresponding synaptic connections in the brain of an adult female fruit fly, Drosophila melanogaster.
