Table 6. Number selectivity in cue-selective neurons recorded in lesion vs. sham rats, statistics.
Listed are the results of a mixed ANOVA on number-selectivity indices across cue-selective neurons in both groups, with factors group (sham or lesion), time (early or late in blocks), and direction (preferred or anti-preferred).
| Planned comparisons (each tests whether indices are significantly shifted from zero): | Planned comparison: lesion vs. sham | ||||||
|---|---|---|---|---|---|---|---|
| time X direction group | lesion preferred direction |
lesion anti-preferred direction |
late in blocks preferred direction lesion vs. sham | effects of hemisphere | |||
| early in blocks | late in blocks | early in blocks | late in blocks | ||||
| F | 5.7 | 2.0 | 0.1 | 3.1 | 1.1 | 3.1 | F’s<0.5 |
| df | 1,90 | 1,90 | 1,90 | 1,65 | 1,90 | 1,90 | 1,88 |
| p | <0.05 | 0.16 | 0.71 | 0.08 | 0.30 | 0.081 | p’s>0.47 |
For the last column, the hemisphere in which the recording was made was included as an additional factor. An additional ANOVA comparing the magnitude of number indices (absolute value) late in the block in the preferred direction revealed that number indices were significantly larger in lesions vs. shams (sham: μ=0.085±0.008; lesion: μ=0.13±0.018, F1,90=5.8, p<0.05). df = degrees of freedom.
