Figure 3. The effects of intermittent threshold compensation on supernormality, measured as the threshold decrease at a conditioning-test interval of 7 ms.

Despite the effective control of threshold (C, same data as in Fig. 1A), there were still changes in the conditioned threshold (measured using a conditioning-test interval of 7 ms, B) and supernormality (A). A illustrates mean data ±s.e.m. for five subjects.
