definition
| - The supra-esophageal ganglion of the central nervous system, composed of three primitive ganglia known as protocerebrum, deuterocerebrum and tritocerebrum. In the context of Drosophila it refers to the pre-oral ganglionic mass of the central nervous system containing the ventral ganglia.
- Anterodorsal portion of the central nervous system. The neuromeres considered to be part of the brain vary by stage. In the larva, the cerebral (supraesophageal) neuromeres, which form a bilateral pair of lobes, constitute the brain (Urbach and Technau, 2003; Li et al., 2014; Crews, 2019). During metamorphosis, the gnathal ganglion separates from the prothoracic neuromere and fuses with the supraesophageal ganglion, to become the ventral part of the adult brain (Ito et al., 2014; Hartenstein et al., 2018; Kendroud et al., 2018).
