| Abstract(in English) | Recent investigations have shown that, in the Drosophila olfactory system, olfactory receptor neurons(ORNs) are comparatively narrowly tuned to odors while second-order projection neurons(PNs) are broadly tuned. This results from a nonlinear transformation between ORN and PN responses. Since PNs will be able to use their dynamic range more efficiently than ORNs, this transformation is considered to be helpful for the decoder to discriminate between odors. However, there are no quantitative arguments for this role. In this study, we modeled a neural circuit of the Drosophila primary olfactory center, and investigated quantitatively this role based on infomax principle. |
