Abstract

We investigated the event-related power decrease (event-related desynchronization: ERD) of the alpha bands associated with the anticipation of affective images. Participants (n=19) were presented with emotionally positive or negative images under different anticipatory conditions, and their brain responses were recorded using magnetoencephalography (MEG). In the Affective Cue conditions, the cue stimulus indicated the emotional valence (positive or negative) of the image. In the Null Cue condition, the cue stimulus did not include any information about the valence of the image, and in the No Cue condition, the affective image was presented without a preceding cue. The cues in the affective and null conditions were followed by emotional images. During the anticipation period for the affective image, the alpha ERD preceding an anticipated negative image was larger than that preceding an anticipated positive image; this effect had an occipital dominance. Furthermore, during the anticipation period, the lower-2-alpha ERD of the right frontal area showed the same result. These results demonstrate that anticipation of negative stimuli induced alpha ERD in both the visual and the right frontal cortex, indicating that top-down modulation may be provided by the right frontal cortex to the visual cortex.

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

  • Lower alpha (8-10 Hz) may be more specifically involved in anticipation than upper alpha.

    “Previous findings suggest differentiating lower (8-10 Hz) and upper (10-12 Hz) 𝛼, as lower 𝛼 may be more specifically involved in anticipation (Onoda et al., 2007).”
  • Alpha suppression appears sensitive to cues indicating threat, with stronger suppression while negative versus positive pictures or painful versus nonpainful stimuli were anticipated.

    “Alpha suppression presumably reflects preparatory activity in the visual cortex (Van Dijk, Schoffelen, Oostenveld, & Jensen, 2008) and appears sensitive to cues indicating threat, with stronger suppression while negative versus positive pictures (Onoda et al., 2007) or painful versus nonpainful stimuli (Babiloni et al., 2003) were anticipated.”

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.
