Interventional randomised, double-blind, parallel-group, placebo-controlled, exploratory study investigating the effects of Lu AA21004 on cognition and BOLD fMRI signals in subjects remitted from depression and controls

� to determine whether Lu AA21004 compared to placebo in subjects remitted from depression modulates the blood oxygen level dependent (BOLD) signal in functional magnetic resonance imaging (fMRI) of the brain areas associated with executive function (working memory) during performance of the N-back task. The regions of interest are within the prefrontal cortex and anterior cingulate � to determine whether Lu AA21004 compared to placebo in subjects remitted from depression modulates the blood oxygen level dependent (BOLD) signal in functional magnetic resonance imaging (fMRI) of the brain areas associated with spatial memory during performance of the Arena task., The region of interest is hippocampus � to evaluate the effects of Lu AA21004 compared to placebo in subjects remitted from depression on the BOLD signal in fMRI in other brain regions involved in the regulation of cognitive processes during working memory and planning performance (N-back and Arena task)
