Two-way ANOVA for the Gaussian fitting parameters
| Amplitude | Bandwidth | Maximum d′ | |
|---|---|---|---|
| Population (trained, n = 266; control, n = 215) | |||
| p | 0.001 | 0.006 | <0.001 |
| Orientation preference (trained, n = 258; control, n = 223) | |||
| p | 0.906 | 0.029 | 0.005 |
| Population × orientation preference | |||
| p | 0.509 | 0.176 | 0.112 |
The main factors were (1) trained population versus control population and (2) orientation preference of the neurons (±45° from trained orientation vs ± 45° from orthogonal orientation). p < 0.05 is indicated in bold. Training significantly affected each of the three measures, and neurons with orientation preferences close to the trained orientation had bandwidths and maximum d′s that were significantly different than neurons preferring other orientations. No significant interactions were seen.
