Figure 9. Number of labellar movements during the first five trials is predictive of the expression of 1 hr PER habituation memory. A-B.

1 hour memory of PER habituation for the wildtype flies that emitted 3 or fewer (A), or 4 or more (B) labellar movements during the first five trials. C-D. 1 hour memory for rutabaga that produced 0 (C) or 1–5 labellar movements during the first five trials.
