Table 1. Best-fit parameters from fitting the transient-sustained (TS) model in Eq. (14) to response data for example Y and X cells, cf. Fig. 10.

| t1 (ms) | 38.7 | 19.1 |
| τ1 (ms) | 5.5 | 2.7 |

| Rbkg (spikes/s) | 6.5* | 15.3* |
| ts (ms) | 62.5* | 62.5* |
| error (ε) TS-model | 0.029 | 0.022 |
| error (ε) CS-model | 0.071 | 0.040 |
The number marked with asterisks are not fitted: Rbkg is found by averaging the background response prior to the stimulus-evoked response, and ts is fixed at 62.5 ms (see main text). Fitting errors (Eq. 1) for both the TS-model and the CS-model (center-surround model, Eq. 6) are also listed.
