Left, on the right side, a topdown view (CCFv3) of 156,190 semiautomatically annotated somas is presented, depicting six selected brain regions color coded along the anteriorposterior axis (left). Corresponding soma locations are plotted as dots (right). The different colors of the somas represent different users who contributed to the annotations. Right, closeup views of the eight selected regions mentioned in a , left. Autotraced dendrites are also shown for those neurons for which somas have been annotated by different users. The six selected regions include the main olfactory bulb (MOB), anterior olfactory nucleus (AON), nucleus accumbens (ACB), the CP, field CA1 (CA1) and the inferior colliculus, external nucleus (ICe). The panel displays the number of annotated somas and users involved in the region.
