These all belong to the Notch OFF hemilineage, as Notch ON progeny develop as glial cells (Mark et al., 2021). Their axons project in anterior and posterior directions near the ventral midline (Mark et al., 2021). lineage 23 embryonic neuron hemilineage 23B embryonic neuron NB7-4 Notch OFF hemilineage embryonic-born neuron VFB:FBbt_00048894 NB7-4 lineage embryonic neuron NB7-4 hemilineage B primary neuron hemilineage 23B primary neuron fly_anatomy.ontology NB7-4 lineage neuron
