marginally significantP = 0.0549
In αCaMKII +/− mice, the decoding accuracies for speed were significantly higher than those expected by chance [paired t test, t (4) = 3.965, P = 1.66 × 10 −2 ; on average, 57.8 ± 9.6 cells are used for decoding], and those for position and motion direction were better than chance to a marginally significant degree [paired t test, position, t (4) = 2.687, P = 0.0549; motion direction, t (4) = 2.711, P = 0.05349].
