Dense EM-based reconstruction of the interglomerular projectome in the zebrafish olfactory bulb

The authors used new 3D electron microscopy techniques and analyses to reconstruct virtually all neurons in the olfactory bulb of a zebrafish larva. The results reveal specific patterns of projections between the functional modules of the olfactory bulb, the glomeruli. This network provides an anatomical basis for distributed olfactory computations.
