The significant responses column indicates the fraction of cells that generated an αAR (32 s stimulus) or αMR significantly above the spontaneous firing rate of the cell (t test, p < 0.05). For response amplitude, mean ± SD of the αAR and αMR is shown.

↵aComparing response amplitudes, the AR32 was significantly larger than the AR1 for all cell classes (Wilcoxon's signed-rank test, p < 0.05). Comparing AR32 and MR, only the values with asterisks were significantly different (p < 0.005 Wilcoxon's signed-rank test; all other paired-mean comparisons for AR32 vs MR had p > 0.05 for both Wilcoxon's signed-rank and paired t test). For time constants, the geometric mean ± SD is shown.
