hΔB [FBbt_00052278]

Adult fan-shaped body horizontal delta neuron that has both of its arbors mainly in layer 3 and the ventral part of layer 4 of the fan-shaped body (Scheffer et al., 2020; Hulse et al., 2021). There are around 19 of these cells per organism, which divide the fan-shaped body into approximately 12 columns (Hulse et al., 2021). These neurons receive input from PFN cells and track the travel direction of the fly, irrespective of its heading (Lu et al., 2022).
