fMRI Analysis | Results | Regions |
---|---|---|
A) Effect of MIST Task “Stress” Condition: “Stress” – “Control” All Participants |
Increased Activity During “Stress” | Right Superior / Middle Temporal Right Middle Occipital / Cuneus |
Decreased Activity During “Stress” | Left Middle Frontal / Anterior Cingulum Left Caudate / Inferior Frontal / Insula Right Caudate Left Angular |
|
B) Effects of MDD History and E2: “Stress” – “Control” MDD History and E2 as factors |
MDD History, E2 Interaction | Left Inferior Frontal Left Angular Gyrus |
Correlations between activity and SACL-Stress Score | Left Angular Gyrus: Negative Correlation in MDD-/E2+ Left Angular Gyrus Positive Correlation in MDD-/E2- |
|
C) Correlation between Activity and Subjective Stress: “Stress” – “Control” All Participants SACL-Stress Score as Covariate |
Positive Correlation between Activity and SACL-Stress Score | No Significant Regions |
Negative Correlation between Activity and SACL-Stress Score | Left Precentral Posterior Cingulum / Precuneus Left Angular / Supramarginal Left Precentral Gyrus Left Inferior Temporal Left Superior Temporal Left Superior Temporal Anterior Cingulum Left Inferior / Middle Temporal Supplementary Motor Area Right Superior / Middle Temporal |
|
D) Group Differences in Correlations between Activity and Subjective Stress: “Stress” – “Control” Group as factor SACL-Stress Score as Covariate |
Correlations between Activity and SACL-Stress Score | Right Inferior Frontal: Positive correlation in MDD+/E2+ Right Temporal/ Insula: Positive Correlation in MDD+/E2- |
