Abstract

The human amygdala is thought to play a pivotal role in the processing of emotionally significant sensory information. The major subdivisions of the human amygdala-the laterobasal group (LB), the superficial group (SF), and the centromedial group (CM)-have been anatomically delineated, but the functional response properties of these amygdala subregions in humans are still unclear. We combined functional MRI with cyto-architectonically defined probabilistic maps to analyze the response characteristics of amygdala subregions in subjects presented with auditory stimuli. We found positive auditory stimulation-related signal changes predominantly in probabilistically defined LB, and negative responses predominantly in SF and CM. In the left amygdala, mean response magnitude in the core area of LB with 90-100% assignment probability was significantly larger than in the core areas of SF and CM. These differences were observed for pleasant and unpleasant stimuli. Our findings reveal that the probabilistically defined anatomical subregions of the human amygdala show distinctive fMRI response patterns. The stronger auditory responses in LB as compared with SF and CM may reflect a predominance of auditory inputs to human LB, similar to many animal species in which the majority of sensory, including auditory, afferents project to this subdivision of the amygdala. Our study indicates that the intrinsic functional differentiation of the human amygdala may be probed using fMRI combined with probabilistic anatomical maps.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Males with positive resting-state functional connectivity between parieto-occipital regions and the basolateral amygdala may have memory problems, because the basolateral amygdala is important for memory in addition to emotional processing.

    “Although all sub-regions are relevant for emotional processing (Ball et al., 2007, Hurlemann et al., 2008, Bzdok et al., 2013a), BLA is additionally important for memory function (Bzdok et al., 2013a); therefore, males demonstrating positive RSFC between parieto-occipital and BLA may report problems with memory functions.”
  • The AM is thought to automatically extract biological significance from the environment.

    “This brain region is thought to automatically extract biological significance from the environment (Ball et al. 2007; Sander et al. 2003; Bzdok et al. 2011; Müller et al. 2011).”

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.
