The partial central complex network formed by PB-innervating neurons. (A) The innervation diagram of the network. Each neuron type is represented by a color line with arrowheads for axonal innervation and solid circles for dendritic innervation. Each color indicates a specific neuron class. (B) The large-scale circuit diagram of the central complex showing the relationship between neuron classes. The arrowheads and solid circles are defined as in (A). EIP and CVP are input neuron classes for their axonal innervation in PB while other classes are classified as output neurons for their dendritic innervation in PB. The PB local neuron class is not shown. The present study focuses on the recurrent circuits formed by EIP, PEI, and PEN.
