Figure 7.

Fuzzy coding is not a function of stimulus duration. Three recordings from a w¹¹¹⁸ control larva, showing its responses to three successive 5 s stimulations with butanol (2%). Eight OSNs were detected in these recordings. Top, Three successive raw traces, each corresponding to a stimulus, together with the firing activity for each OSN. Bottom, Responses of these OSNs expressed in terms of their activity above or below the response threshold. The responses for each 5 s stimulus are divided into five successive 1 s periods. Red, Excitation; blue, inhibition; black, no response.
