Abstract

An emerging hypothesis regarding the mechanisms underlying antidepressant pharmacotherapy suggests that these agents benefit depressed patients by reversing negative emotional processing biases (Harmer, 2008). Neuropsychological indices and functional neuroimaging measures of the amygdala response show that antidepressant drugs shift implicit and explicit processing biases away from the negative valence and toward the positive valence. However, few studies have explored such biases in regions extensively connected with the amygdala, such as the pregenual anterior cingulate cortex (pgACC) area, where pre-treatment activity consistently has predicted clinical outcome during antidepressant treatment. We used functional magnetic resonance imaging (fMRI) to investigate changes in haemodynamic response patterns to positive vs. negative stimuli in patients with major depressive disorder (MDD) under antidepressant treatment. Participants with MDD (n = 10) underwent fMRI before and after 8 wk sertraline treatment; healthy controls (n = 10) were imaged across an equivalent interval. A backward masking task was used to elicit non-conscious neural responses to sad, happy and neutral face expressions. Haemodynamic responses to emotional face stimuli were compared between conditions and groups in the pgACC. The response to masked-sad vs. masked-happy faces (SN-HN) in pgACC in the depressed subjects was higher in the pre-treatment condition than in the post-treatment condition and this difference was significantly greater than the corresponding change across time in the controls. The treatment-associated difference was attributable to an attenuated response to sad faces and an enhanced response to happy faces. Pre-treatment pgACC responses to SN-HN correlated positively with clinical improvement during treatment. The pgACC participates with the amygdala in processing the salience of emotional stimuli. Treatment-associated functional changes in this limbic network may influence the non-conscious processing of such stimuli by reversing the negative processing bias extant in MDD.

  • Blunted dlPFC activation has been accompanied by exaggerated amygdalar activation when processing subliminal negative stimuli.

    “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 [169]

    The Introduction reports an abnormally increased amygdala response to masked-sad faces in unmedicated depressed participants, supporting the exaggerated-amygdala part of the claim. The fMRI Results and Discussion describe changes in the pgACC, ventrolateral prefrontal cortex and lateral frontal polar cortex, but do not report blunted dlPFC activation accompanying that amygdala response. Passage-level page numbers are unavailable in our copy. (LLM, conf=0.85)

  • SSRI treatment (sertraline) reduced activation in the pgACC (BA24/32) (as well as left medial OFC and left vlPFC) in response to masked sad vs. happy faces.

    “For example, an early study reported that SSRI treatment (sertraline) reduced activation in the pgACC (BA24/32) (as well as left medial OFC and left vlPFC) in response to masked sad vs. happy faces [169].”

    From Prefrontal cortex and depression (2022) · cites this paper as [169]

    The fMRI Results report reduced masked-sad versus masked-happy (SN-HN) response in the right pgACC after sertraline treatment. They report reductions in the left medial OFC and left vlPFC for masked-sad versus masked-neutral (SN-NN) faces, not the sad-versus-happy contrast attributed to all three regions. The cited passages do not specify BA24/32 for the pgACC. (LLM, conf=0.90)

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.
