adult intrinsic protocerebral bridge 18 glomeruli-2 glomeruli neuron [FBbt_00111057]

Large field neuron of the central complex that is intrinsic to the protocerebral bridge (Lin et al., 2013; Wolff et al., 2015). It has dendritic arbors in 18 glomeruli, and axon terminals distributed in two glomeruli spaced seven glomeruli apart (Wolff et al., 2015). There are three subtypes that differ on the location of the axon terminals (Lin et al., 2013). One subtype has terminals in the ipsilateral glomerulus 7 and contralateral glomerulus 2; another with terminals in the ipsilateral glomerulus 6 and contralateral glomerulus 3; and the last with terminals in the ipsilateral glomerulus 5 and contralateral glomerulus 4 (Lin et al., 2013; Wolff et al., 2015).

SpsP [FBbt_00111514]

Interneuron that has dendritic arborizations in the ipsilateral superior posterior slope and sparse axon terminals in glomeruli 2-9 of the ipsilateral protocerebral bridge (Wolff et al., 2015). Occasionally, glomerulus 1 is also innervated and arbors may extend into the contralateral protocerebral bridge (Wolff et al., 2015). It develops from the PBp1 neuroblast (Kandimalla et al., 2023).

Δ7 [FBbt_00049807]

Large field neuron of the central complex that is intrinsic to the protocerebral bridge (PB) with dendritic arbors in all 18 glomeruli and axon terminals in glomeruli that are seven glomeruli apart (Lin et al., 2013; Wolff et al., 2015). There are four subtypes, collectively having presynaptic terminals in all glomeruli (Wolff et al., 2015). They have inhibitory output onto E-PG neurons in their output glomeruli and receive input from E-PG neurons of other PB regions (Turner-Evans et al., 2020). They are glutamatergic (Turner-Evans et al., 2020) and all develop from neuroblast PBp1 (Kandimalla et al., 2023).

Δ7_PB8+1+9 [FBbt_00007539]

Large field protocerebral bridge intrinsic neuron that has dendritic arbors in all 18 glomeruli and axon terminals distributed in three glomeruli that are seven glomeruli apart (Lin et al., 2013; Wolff et al., 2015). Its axonal terminals are in ipsilateral glomerulus 8 and contralateral glomeruli 1 and 9 (Lin et al., 2013; Wolff et al., 2015).
