Fig. 6. A strong conditioning stimulus caused adaptation of the sensillar potential and action potential responses. (A) Compared with a response without a preceding strong stimulus (upper trace), the sensillar potential amplitude and the action potential frequency were reduced (lower trace) after an adapting stimulus. (B) After lowpass-filtering and normalizing both responses to the same maximal amplitude, the faster decline (filled arrow) to baseline of the sensillar potential in the adapted state (broken line) became obvious. But the half-time of the rising phase (t_{1/2 rise}; open arrow) was less affected. Stimulus duration was 50 ms. BAL, bombykal.
