Amygdala Temporal voice area Auditory emotions fMRI a b s t r a c tDiscriminating between auditory signals of different affective value is critical to successful social interaction. It is commonly held that acoustic decoding of such signals occurs in the auditory system, whereas affective decoding occurs in the amygdala. However, given that the amygdala receives direct subcortical projections that bypass the auditory cortex, it is possible that some acoustic decoding occurs in the amygdala as well, when the acoustic features are relevant for affective discrimination. We tested this hypothesis by combining functional neuroimaging with the neurophysiological phenomena of repetition suppression (RS) and repetition enhancement (RE) in human listeners. Our results show that both amygdala and auditory cortex responded differentially to physical voice features, suggesting that the amygdala and auditory cortex decode the affective quality of the voice not only by processing the emotional content from previously processed acoustic features, but also by processing the acoustic features themselves, when these are relevant to the identification of the voice's affective value. Specifically, we found that the auditory cortex is sensitive to spectral high-frequency voice cues when discriminating vocal anger from vocal fear and joy, whereas the amygdala is sensitive to vocal pitch when discriminating between negative vocal emotions (i.e., anger and fear). Vocal pitch is an instantaneously recognized voice feature, which is potentially transferred to the amygdala by direct subcortical projections. These results together provide evidence that, besides the auditory cortex, the amygdala too processes acoustic information, when this is relevant to the discrimination of auditory emotions.© 2016 Elsevier Ltd.

“…For instance, Calvo et al (2012) suggested, based on a series of experiments with 'blended' expressions (whereby the mouth is smiling but the eyes present a different basic emotion), that featural information from the mouth is accessible earlier (< 170 ms after onset) than a configural representation in which the conflicting content is included. As feature-based processing has been suggested to be left lateralized (Bourne et al, 2009), it might account for right visual field biases regarding positive emotions (i.e. happiness, and perhaps surprise, both of which have large featural changes).…”

“…There is some evidence that featural processing of faces is leftlateralized (Bourne, Vladeanu, & Hole, 2009). Inverted ECFT trials thus control for the lowlevel visual properties related to the presentation of face stimuli, while also ruling out the possibility that any differences in biases between expressions can be accounted for by the fact that these simply have different visual properties, such as the distinct featural change in the mouth that indicates happiness.…”

“…Critically for present purposes, inversion impairs individuals' ability to discriminate emotions efficiently (though still above chance; Bimler, Skwarek, & Paramei, 2013), supporting the idea that emotional face perception relies on configural processes which proceed best when the faces are presented upright. These configural processing mechanisms are thought to be right-lateralized (Abbott, Wijeratne, Hughes, Perre, & Lindell, 2014;Bourne, Vladeanu, & Hole, 2009). …”

AbstractLeft hemiface biases observed within the Emotional Chimeric Face Task (ECFT) support emotional face perception models whereby all expressions are preferentially processed by the right hemisphere. However, previous research using this task has not considered that the visible midline between hemifaces might engage atypical facial emotion processing strategies in upright or inverted conditions, nor controlled for left visual field (thus right hemispheric)visuospatial attention biases. This study used novel emotional chimeric faces (blended at the midline) to examine laterality biases for all basic emotions. Left hemiface biases were demonstrated across all emotional expressions and were reduced, but not reversed, for inverted faces. The ECFT bias in upright faces was significantly increased in participants with a large attention bias. These results support the theory that left hemiface biases reflect a genuine bias in emotional face processing, and this bias can interact with attention processes similarly localized in the right hemisphere.3

“…Looking at a forest, one can view it holistically in its global meaning (a forest), or focus on specific trees and attend to their local features. Many studies with healthy and brain-damaged patients have demonstrated that these two complementing modes of perception are lateralized in the brain; the RH mediates the grasp of the overall picture, while the LH is associated with attention to the details [275, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285]. For instance, patients with a unilateral brain damage were shown a series of stimuli (letters or geometrical shapes) consisting of elements which had different meanings than the global feature (see example in Fig.…”

Mounting evidence suggest that the right-hemisphere (RH) has a relative advantage, over the left-hemisphere (LH), in mediating social intelligence - identifying social stimuli, understanding the intentions of other people, awareness of the dynamics in social relationships, and successful handling of social interactions. Furthermore, a review and synthesis of the literature suggest that pro-social attitudes and behaviors are associated with physiological activity in the RH, whereas unsocial and anti-social tendencies are mediated primarily by the LH. This hemispheric asymmetry is rooted in several neurobiological and functional differences between the two hemispheres. (I) Positive social interactions often require inhibiting one's immediate desires and considering the perspectives and needs of others. Given that self-control is mediated by the RH, pro-social emotions and behaviors are, therefore, inherently associated with the RH as it subserves the brain's self-restraint mechanisms. (II) The RH mediates experiences of vulnerability. It registers the relative clumsiness and motor weakness of the left limbs, and it is involved, more than the LH, in processing threats and mediating fear. Emotional states of vulnerability trigger the need for affiliation and sociality, therefore the RH has a greater role in mediating pro-social attitudes and behaviors. (III) The RH mediates a holistic mode of representing the world. Holistic perception emphasizes similarities rather than differences, takes a long-term perspective, is associated with divergent thinking and seeing other points-of-view, and it mediates a personal mode of relating to people. All these features of holistic perception facilitate a more empathetic attitude toward others and pro-social behaviors.
