Left panel: results of Experiment 1. “BL” = freezing during the baseline period (prior to light-shock pairings) in the training session, “Post-Shock” = freezing during the three post-shock periods of the training session, “Context Test” = freezing during the test session in Context A, “Tone” = freezing averaged over the entire tone test in Context B (20 tone presentations). Right panel: results from the Tone Test session plotted in 5-trial blocks. “BL”: freezing during the baseline period just prior to the presentation of the first tone stimulus. Sham = sham lesioned rats, Ipsi = lesions of RSC and AuV in the same hemisphere, Contra = lesions of the RSC and AuV is opposite hemispheres. Error bars represent ±1 SEM. *p < .05.
