Table 2.

Data table for immunoblot analyses of PKC βII and β-actin levels and measures of freezing behavior to cue and context probe trials. Training conditions are shown as columns, measurements (mean ± SEM) are shown as rows. Significant differences between hemispheres or between training conditions are indicated in text and figures.
