Neural bases of the non-conscious perception of emotional signals

Open access
Tamietto, Marco, de Gelder, Beatrice·2010·Nature Reviews Neuroscience

Abstract

Many emotional stimuli are processed without being consciously perceived. Recent evidence indicates that subcortical structures have a substantial role in this processing. These structures are part of a phylogenetically ancient pathway that has specific functional properties and that interacts with cortical processes. There is now increasing evidence that non-consciously perceived emotional stimuli induce distinct neurophysiological changes and influence behaviour towards the consciously perceived world. Understanding the neural bases of the non-conscious perception of emotional signals will clarify the phylogenetic continuity of emotion systems across species and the integration of cortical and subcortical activity in the human brain.

  • People are generally not consciously aware of subtle changes in an interaction partner's face and do not voluntarily react to these changes.

    “The literature indicates that people are generally not consciously aware of subtle changes in an interaction partner's face and do not voluntarily react to these changes (Dimberg et al., 2000;Tamietto and Castelli, 2009;Tamietto and de Gelder, 2010;Wood et al., 2016).”

    From Connecting minds and sharing emotions through mimicry: A neurocognitive model of emotional contagion (2017) · cites this paper as Tamietto and de Gelder, 2010

    The paper’s “Autonomic and expressive changes” section says that undetected emotional stimuli can elicit spontaneous, rather than intentional, facial reactions, and suggests that this may matter in social interactions. It does not establish that people are generally unaware of subtle changes in an interaction partner’s face; its examples concern emotional expressions perceived non-consciously under particular conditions.

  • Areas contributing to interoceptive predictive coding include specific brainstem (nucleus of the solitary tract, periaqueductal gray, locus coeruleus), subcortical (substantia innominata, nucleus accumbens, amygdala), and cortical (insular, orbitofrontal, and anterior cingulate) regions, potentially forming at least a loose hierarchy.

    “We suggest that areas contributing to interoceptive predictive coding include specific brainstem (nucleus of the solitary tract, periaqueductal gray, locus coeruleus), subcortical (substantia innominata, nucleus accumbens, amygdala), and cortical (insular, orbitofrontal, and anterior cingulate) regions, potentially forming at least a loose hierarchy”

  • Unconscious perception of emotional stimuli is related with the functional integrity of subcortical areas that receive executive cortical feedback from the cortical network only during wakefulness.

    “the unconscious perception of emotional stimuli has been related with the functional integrity of subcortical areas that receive an executive cortical feedback from the cortical network (e.g., dlPFC, OFC, and posterior cingulate cortex) only during wakefulness”

    From The Functional Role of Dreaming in Emotional Processes (2019) · cites this paper as Tamietto and De Gelder, 2010

    The 'Neural integration and awareness' section links non-conscious perception of emotional stimuli to the functional integrity of subcortical structures. It associates re-entrant cortical feedback with visual awareness and suggests that this feedback may be absent during non-conscious perception. It does not say that executive feedback from the named cortical network reaches those structures only during wakefulness. (LLM, conf=0.88)

  • The periaqueductal grey contributes to non-conscious emotion perception and reflexive behaviors aimed at helping to escape threatening situations.

    “A small region in the brainstem, the periaqueductal grey, contributes to non-conscious emotion perception and reflexive behaviors aimed at helping to escape threatening situations [145,150].”

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.
