| AM | 9.96 [6.88, 14.30] | 0.39 [5e-3, 0.87] | 8.03 [3.83, 11.04] | 3.39 [2.37, 6.50] |

Amplitude parameters a are expressed in %-response reduction of firing rate to repeat with respect to orthogonal trials. Exponential time constants τ are expressed in units of trials. The decay of adaptation in thalamic areas LGN and LP was significantly better fit by single-exponential decay models. Therefore, no parameters for the second exponential component are provided for these areas. Values in parentheses indicate bootstrapped 95% confidence intervals.
