Abstract

The recently discovered default mode network (DMN) is a group of areas in the human brain characterized, collectively, by functions of a self-referential nature. In normal individuals, activity in the DMN is reduced during nonself-referential goal-directed tasks, in keeping with the folk-psychological notion of losing one's self in one's work. Imaging and anatomical studies in major depression have found alterations in both the structure and function in some regions that belong to the DMN, thus, suggesting a basis for the disordered self-referential thought of depression. Here, we sought to examine DMN functionality as a network in patients with major depression, asking whether the ability to regulate its activity and, hence, its role in self-referential processing, was impaired. To do so, we asked patients and controls to examine negative pictures passively and also to reappraise them actively. In widely distributed elements of the DMN [ventromedial prefrontal cortex prefrontal cortex (BA 10), anterior cingulate (BA 24/32), lateral parietal cortex (BA 39), and lateral temporal cortex (BA 21)], depressed, but not control subjects, exhibited a failure to reduce activity while both looking at negative pictures and reappraising them. Furthermore, looking at negative pictures elicited a significantly greater increase in activity in other DMN regions (amygdala, parahippocampus, and hippocampus) in depressed than in control subjects. These data suggest depression is characterized by both stimulus-induced heightened activity and a failure to normally down-regulate activity broadly within the DMN. These findings provide a brain network framework within which to consider the pathophysiology of depression.

  • Negatively biased self-generated thoughts and heightened activity of the DMN have been associated with depression.

    “For example, negatively biased self-generated thoughts and heightened activity of the DMN have been associated with depression (20, 21, 54, 56–58), as well as maladaptive rumination (55).”

    From SSRI Treatment Response Prediction in Depression Based on Brain Activation by Emotional Stimuli (2020) · cites this paper as [58]

    The Discussion reports overactive DMN regions in depressed subjects during emotional tasks and hypothesizes increased self-referential focus in depression. It does not establish that the subjects’ self-generated thoughts were negatively biased; the negative material in the study was presented as pictures. (LLM, conf=0.82)

  • Blunted dlPFC activation has been accompanied by exaggerated amygdalar activation when viewing and reappraising negative pictures.

    “Thus, blunted dlPFC activation has been accompanied by exaggerated amygdalar activation when (1) viewing and reappraising negative pictures [167], (2) processing subliminal negative stimuli [168, 169] (Fig. 4d) and negative words”

    From Prefrontal cortex and depression (2022) · cites this paper as [167]

    The Imaging Data section reports greater left-amygdala responses to negative pictures in depressed participants and lower activation in the left dorsal medial prefrontal cortex during viewing. It does not report blunted dorsolateral prefrontal (dlPFC) activation. Figure 2 and the Discussion indicate that the amygdala group difference was found during viewing, not reappraisal. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Higher activity in DMN regions during perception of negative stimuli in patients with MDD is a known alteration.

    “Higher activity in DMN regions during perception of negative stimuli in patients with MDD is a known alteration (58).”
  • Mood disorders including major depressive disorder and bipolar disorder are associated with enhanced activity and connectivity of default network structures with key regions of the limbic and/or salience networks.

    “For example, mood disorders including major depressive disorder and bipolar disorder are associated with enhanced activity and connectivity of DN structures with key regions of the limbic and/or salience networks.147,148,215–219”
  • MDD resting-state data show vmPFC and limbic hyperactivity and greater connectivity between medial prefrontal regions and an affective network including amygdala.

    “Resting-state data from samples with major depressive disorders demonstrate hyperactivity in the vmPFC and limbic structures (e.g., amygdala, bed nucleus of the stria terminalis [BNST])25, as well as increased connectivity between medial prefrontal regions (including the vmPFC) and other networks including an affective network to which the amygdala is interconnected26.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
