Abstract

A considerable body of research has focused on neural responses evoked by emotional facial expressions, but little is known about mother-specific brain responses to infant facial emotions. We used near-infrared spectroscopy to investigate prefrontal activity during discriminating facial expressions of happy, angry, sad, fearful, surprised and neutral of unfamiliar infants and unfamiliar adults by 14 mothers and 14 age-matched females who have never been pregnant (non-mothers). Our results revealed that discriminating infant facial emotions increased the relative oxyHb concentration in mothers' right prefrontal cortex but not in their left prefrontal cortex, compared with each side of the prefrontal cortices of non-mothers. However, there was no difference between mothers and non-mothers in right or left prefrontal cortex activation while viewing adult facial expressions. These results suggest that the right prefrontal cortex is involved in human maternal behavior concerning infant facial emotion discrimination.

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

  • Once parenthood is established, greater specialization of the brain occurs, with right-sided lateralization in the prefrontal cortex for emotional discrimination of infant relative to adult faces (Nishitani et al., 2011).

    “Once parenthood is established, data further indicate that greater specialization of the brain occurs with for example a right–sided lateralization in the prefrontal cortex (PFC) for emotional discrimination of infant relative to adult faces (Nishitani 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.
