Table 3. Correlations between the AMY and the MTL memory regions.
MTL regions | AMY-MTL correlations: R scores (emotional rRS) | AMY-MTL correlations: R scores (neutral rRS) | AMY-MTL correlations: R scores (emotional kRS) | AMYgdala-MTL correlations: R scores (neutral kRS) |
---|---|---|---|---|
AMY (R) | N/A | N/A | N/A | N/A |
HC (head) (R) | 0.94**** | 0.97**** | 0.98**** | 0.86* |
HC (body) (L) | 0.82* | - | 0.9*** | - |
HC (tail)/PPHG (R) | 0.87** | - | - | - |
HC (tail)/PPHG (L) | 0.77* | - | 0.81* | 0.76* |
Correlations were calculated between the AMY and the MTL memory regions showing greater recollection- vs. familiarity-based retrieval success activity for emotional than for neutral pictures. The greatest differences were in the case of recollection-based responses. Similar to Table 2, the signals from posterior HC/parahippocampal regions were averaged together. RS, (hits - misses); rRS, recollection-based RS; kRS, familiarity-based RS. *, P < 0.05; **, P < 0.01; ***, P < 0.005; ****, P < 0.0005.
