Differences between receptive field measurements of VS cells. Difference indices (DIs) for each VS cell were calculated between the average receptive field (RF _mean) of a cell and each receptive fields of the same cell for different flies (RF _n). The DIs are shown with gray dots and the distribution represents the variability of our receptive field measurements a cell. The black diamond represents the DI between the average receptive field (RF _mean) of a cell and the receptive field (RF _{Krapp et al. 1998}) of the same cell determined previously by Krapp et al. (1998). Data are the same as in Fig. 2
