Neuronal parts list and wiring diagram for a visual system.

ABSTRACT: A catalogue of neuronal cell types has often been called a 'parts list' of the brain¹, and regarded as a prerequisite for understanding brain function^2,3. In the optic lobe of Drosophila, rules of connectivity between cell types have already proven to be essential for understanding fly vision^4,5. Here we analyse the fly connectome to complete the list of cell types intrinsic to the optic lobe, as well as the rules governing their connectivity. Most new cell types contain 10 to 100 cells, and integrate information over medium distances in the visual field. Some existing type families (Tm, Li, and LPi)^6-10 at least double in number of types. A new serpentine medulla (Sm) interneuron family contains more types than any other. Three families of cross
