Connectivity Interaction Effects for Associations Between LI and CA3–HPC/CA1–IL Connectivity Across only Aged Rats
| y | x | Hemisphere | Regression parameters | ANCOVA | ||
|---|---|---|---|---|---|---|
| β(SE) | P | F | P | |||
| LI | CA3–HPC connectivity | left CA3 | −0.47(0.16) | 0.006 | 11.16 | 0.0014 |
| right CA3 | 0.30(0.17) | 0.10 | ||||
| LI | CA1–IL connectivity | left CA1 | −0.41(0.16) | 0.02 | 4.92 | 0.03 |
| right CA1 | 0.10(0.18) | 0.57 | ||||
Analysis of covariance (ANCOVA) was used to determine if slopes differed statistically between hemispheres. Statistically significant regression slopes and slope differences between treatments (at P < 0.05) are in bold type.
