The developing dorsal root ganglia (DRG) have been manually defined at late CS12, CS13 and CS14.

DRG development starts in the cervical region at CS12 and progresses with the thoracic region at CS13, and finally the lumbar and sacral regions at CS14.

The movies in the first column show the painted 3D domains. Cervical - red, thoracic - green, lumbar - yellow and sacral - light blue.
