Abstract

Significance: The periaqueductal gray is a brainstem region that is critical for autonomic regulation and for defensive responses (e.g., “fight,” “flight,” “freeze”). It has been studied extensively in rodents and cats, but less is known about the human periaqueductal gray. The small size and shape of the periaqueductal gray makes it challenging to study using standard noninvasive MRI techniques. We used a high-field strength magnet to examine this region at high resolution while participants viewed emotionally aversive or neutral images. Emotion-related functional activity was concentrated in particular subregions and in ways that are consistent with neurobiological observations in nonhuman animals. This study establishes a technique to uncover the functional architecture of the periaqueductal gray in humans.

  • Functional magnetic resonance imaging studies performed while negatively arousing (aversive) stimuli, including pictures of mutilation and injury in humans, are being processed provide clear evidence of PAG activation and suggest increased functional connectivity between the amygdala and PAG, coupled with a bradycardic effect.

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.
