Scientists Complete the First Full Connectome of a Male Fruit Fly

Researchers have mapped every neuron and synaptic connection in an adult male fruit fly’s brain and central nervous system, creating the largest complete brain map yet by neuron count. The dataset contains 166,691 neurons across the brain and ventral nerve cord, along with 125 million synaptic connections and 11,691 annotated neuron types, according to the published study and accompanying research materials (Google Research, the study).
