Discrimination performance in AM discrimination task as a function of training session. A Top row: Median DP of unified sham control group with interquartile range indicated by the whiskers. Grey boxes indicate the 6-day intervals tested against each other in the main part of the analyses (cf. Figure 4). Center and bottom row: Median DP of the two lesion groups. Note that the animals of both groups are still able to perform the task even after the second lesion, i.e., without auditory cortex. B Mean d’ values (±standard deviation) of the three animal groups over the 45 training sessions. Note that for further analysis we chose to use the same 6-day time intervals as in the discrimination performance shown above.
