Table 4. Quantitative results, including the average beta values (i.e., high-memory-load activation) and the average z scores (i.e., HPN connectivity), within the AAL-based HPN regions in APOE-ε4 carriers and non-carriers.
| Average beta values | Average z scores | ||||
|---|---|---|---|---|---|

*: p < 0.05, compared with APOE-ε4 carriers.
HPN = hippocampal network; AAL = automated anatomical labeling; L = left hemisphere; R = right hemisphere.
