Figure 5

A projection neuron connecting the delta area of the inferior lateral protocerebrum and the mushroom body calyx (ΔILPC–MB unilateral neuron). (A,B) Frontal views of reconstruction of the neuron (black) and mushroom body (grey). Frontal (A) and dorsal views are shown (B). The innervation in the ΔILPC and SMP with smooth and blebby appearance. (C) Neuronal innervation in the mushroom body calyx. The innervation is biased towards the central zone of the calyx. (D) Neuronal innervation in the ΔILPC. Confocal stacks at three different depths are shown. The depth from the posterior brain surface is shown in the top-right panel. The innervation is biased towards the lateral ΔILPC. (E) Response profile of the neuron. The neuron exhibits a brief excitatory response to bombykal. Pe, pedunculus of the mushroom body.
