A prominent feature of calycal connectivity is that projection neurons synapse onto multiple Kenyon cells, and that Kenyon cells receive input from multiple projection neurons, generating an intricate local divergence-convergence network. Accordingly, Kenyon cells may act as coincidence detectors, which integrate the...

Figure 2. Schematic view of the insect olfactory system. It consists of two stages, the antennal lobe (AL) and the Mushroom Body (MB). For the Locust, the AL is a network of approximately 900 excitatory Projection Neurons (PNs) and 300 inhibitory Local Neurons (LN), represented by circles in black and white, respectively. The MB has a huge number of Kenyon Cells (KC) (-50,000 in the locust) receiving inputs from the PNs only.
