Short-term memory for shape information. (a) M-shaped maze. (b) Visually guided and memory-guided tasks. A nonmatching-to-sample test with or without a delay of 20 s was used. (c) Performance of eight wild-type mice. (d) Performance of eight Pcdh-α1,12 mice. (e) The mean and SEM of data are shown in (c) and (g). (f) Averaged amplitudes of performance in the last five sessions (100 trials) of the visually guided and memory-guided tasks. The performance of Pcdh-α1,12 mice in the memory-guided task was significantly worse than that of wild-type mice.
