Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will compare performance on the affective go/no-go task between MDD, BD I and HC, measured by response time, number of omissions and number of errors. The same outcomes will be examined for the neuroimaging tasks. We will compare brain responses of fMRI tasks relative to control conditions between MDD, BD and HC. We will compare responses in predefined ventral and dorsal brain regions (dorsolateral prefrontal cortex (PFC), ventral PFC, orbitofrontal, limbic and subcortical regions). | — |
