Description
Six DD class GABAergic neurons are generated in the embryo to synapse with ventral muscles and receive input from cholinergic neurons in the dorsal nerve cord. After hatching and toward the end of the first larval (L1) stage, DD neurons reverse polarity (i.e., synapse with dorsal muscles, receive ventral cholinergic inputs). Expression profiles were generated from DD neurons in the early L1 stage before the initiation of the remodeling program.
