Neurons innervating the delta area of the inferior lateral protocerebrum (ΔILPC–MB bilateral neuron). (A,B) Frontal and dorsal views of the stained neurons. In total, 5 neurons were labelled in the sample, of which 4 neurons showed bilateral innervation. All 5 neurons innervated the lateral ΔILPC. One neuron projected to the mushroom body calyx in the ipsilateral hemisphere. (C) Confocal stacks of neuronal innervation in the ipsilateral hemisphere. Most innervation was biased towards the lateral ΔILPC. The shape of neuropils is shown with a broken line. (D) Odour response profile of the neurons. The grey box represents the time period of odour presentation (500 ms).
