Figure 6.

Heterogeneity in odor responses among LNs. A, Rasters compare the responses of two different LNs (same as cells LN7 and LN8 in B) with three odors (gray bar; 500 ms). The first of these responds more weakly to hexanal than to linalool or methyl salicylate. The second cell responds equally strongly to all three odors, but latency of the methyl salicylate response is shortest. B, Odor preferences vary across LNs. The number of odor-evoked spikes [as a percentage of the maximum (% of max) response for each cell] is plotted for each odor.
