Adult neuron with its soma close to the saddle (Luan et al., 2020). It expresses rk, allowing it to respond to Bursicon in early adulthood, and can elicit proboscis extension (Luan et al., 2020). It has broad arbors along the superior subesophageal zone, and axons that extend medially before turning ventrally along the midline, then laterally along the medial-inferior edge of the gnathal ganglion (Luan et al., 2020). There are two of these cells per hemisphere (Luan et al., 2020). adult PErk neuron of SEZ adult CNS neuron adult subesophageal zone proboscis extension reflex
