Figure 54. Central complex (CX) neurons with downstream synapses outside the CX.

(A) Neuropil innervation plot of all CX types having downstream connections outside the central complex. Only CX neuron types that have a significant number of presynaptic terminals in other brain regions are shown. The CX is excluded to highlight the connections in non-CX neuropils. The CX innervation of the same neurons can be found in Figure 10 (ellipsoid body [EB] columnar, ER neurons, extrinsic ring [ExR] neurons), Figure 28—figure supplement 1 (FB columnar), and Figure 40—figure supplement 1 (FB tangential neurons). (B) Presynaptic site locations outside of the CX in the right hemibrain for the neuron types shown in (A). Left: frontal view. Right: side view. The locations are overlaid on an anatomical rendering of the relevant neuropils. Dot colors indicate the neuron type. The color code for neuropils is identical in (A) and (B). (C) The total number of synapses across all significant type-to-type connections outside of the CX in the right hemibrain for all neurons of the types shown in (A and B).
