Summary diagram of the olfactory pathway in the protocerebrum. (A) Neuropils connected with the ∆ILPC and LH identified in the present study. Regions involved in pheromone and plant odour processing are shown with black and grey, respectively. (B) Neurite innervation in the ∆ILPC. Grey indicates the area of innervation. Axonal projection of PNs arising from the toroid and cumulus (top) and the dendritic arborization of ∆ILPC neurons are shown (bottom). (C) Spatial distribution of neuronal innervation to the calyx. Output neurons from the MGC and ∆ILPC project to the central zone (black), whereas those from ordinary glomeruli and the LH project to a wider area (grey).
