Fig. 10. Encoding of stimulus duration [20 ms (A), 200 ms (B) or 2000 ms (C)] in the bombykal cell. Neither the evaluated parameters of the sensillar potential nor the action potential response appeared to encode stimulus durations of 20 ms to 2 s. At long stimulus durations of 2000 ms, the duration of the plateau of the sensillar potential matched the stimulus duration without being reflected in the duration of the action potential response. The sensillum was stimulated locally with a dose of 1 µg bombykal. DC, unfiltered recording, AC, pseudo-highpass-filtered signal, St, stimulus signal, recorded by a pressure sensor. Above the AC traces, the initial portions of the action potential responses are shown as inserts at enlarged scale.
