General Information
Term adult fan-shaped body horizontal delta neuron ID (Ontology) FBbt:00007523 (Fly Anatomy)
Definition Adult fan-shaped body delta neuron that connects columns that are separated by half the width of the fan-shaped body (Hanesch et al., 1989; Young and Armstrong, 2010a; Young and Armstrong, 2010b; Hulse et al., 2021), with one column being predominantly input and the other predominantly output (Hulse et al., 2021). These neurons develop from the fan-shaped body pioneer neurons (Andrade et al., 2019).[ FlyBase:FBrf0049409 FlyBase:FBrf0210154 FlyBase:FBrf0210156 FlyBase:FBrf0254510 ]
Also Known As "hDelta" ; "hΔ" ; "pontine neuron P1"
