Abstract

Repetitive transcranial magnetic stimulation (rTMS) studies investigating brain imaging correlates of emotion modulation in healthy volunteers can improve our understanding of the 'affective' impact of this application. In this fMRI study, we focused on lateralized amygdala functioning when processing salient emotional visual stimuli after one high-frequency (HF)-rTMS session. In a 'uniform sample' of 20 right-handed, non-depressed, healthy female subjects we examined whether one HF-rTMS session applied to the left (n=10) or right (n=10) dorsolateral prefrontal cortex (DLPFC) would influence amygdala responses to positively and negatively valenced baby faces. Subjects were given no other instructions than to focus on the emotion the visual stimuli elicited during scanning. One HF-rTMS session did not result in a conscious mood change. Whereas one left-sided HF-rTMS session did not affect amygdala processing of the positive or negative stimuli, after a single right-sided HF-rTMS session we found a significant right amygdala activity attenuation during the processing of negatively valenced baby faces. This finding provides additional evidence supporting the role of the right anterior hemisphere in the processing of negative emotional information, and increases our understanding of HF-rTMS treatment effects in mental disorders.

  • An increase in DLPFC activity may reduce the HPA axis response to stress through indirect and inhibitory connections with the amygdala.

    “As proposed by several authors, an increase in DLPFC activity may reduce the HPA axis response to stress through indirect and inhibitory connections with the amygdala (Baeken et al., 2010(Baeken et al., , 2014;;Herman et al., 2005).”

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.
