Figure 2.

(A) Example of an eyeblink response exhibited by a rat receiving paired presentations of the CS and US (trained). Example taken from session 5, with the animal achieving 82% CRs on this session. Both raw EMG (bottom) and rectified/integrated EMG (top) responses are shown. Shaded bars indicate the timing of the tone CS (dark gray) and airpuff US (light gray). (B) Acquisition rates of trace eyeblink conditioning for consecutively trained animals. There was no difference between EBC→WMZ and WMZ→EBC animals for CR percentage over training. (C) Latency to the hidden platform over training trials for consecutively trained animals. There was no difference between EBC→WMZ and WMZ→EBC animals for latency to the platform over training.
