“…This is consistent with previous evidence for an association between high anxiety and larger right amygdala volume (54) and right amygdala hyperactivity (55). A "valence" model has been discussed in this context (56), which suggests that negative emotions are predominantly processed in the right but not left amygdala, thereby supporting a specific role of the right amygdala in affective disorders.…”

Stress-related variation in the intrauterine milieu may impact brain development and emergent function, with long-term implications in terms of susceptibility for affective disorders. Studies in animals suggest limbic regions in the developing brain are particularly sensitive to exposure to the stress hormone cortisol. However, the nature, magnitude, and time course of these effects have not yet been adequately characterized in humans. A prospective, longitudinal study was conducted in 65 normal, healthy mother-child dyads to examine the association of maternal cortisol in early, mid-, and late gestation with subsequent measures at approximately 7 y age of child amygdala and hippocampus volume and affective problems. After accounting for the effects of potential confounding pre-and postnatal factors, higher maternal cortisol levels in earlier but not later gestation was associated with a larger right amygdala volume in girls (a 1 SD increase in cortisol was associated with a 6.4% increase in right amygdala volume), but not in boys. Moreover, higher maternal cortisol levels in early gestation was associated with more affective problems in girls, and this association was mediated, in part, by amygdala volume. No association between maternal cortisol in pregnancy and child hippocampus volume was observed in either sex. The current findings represent, to the best of our knowledge, the first report linking maternal stress hormone levels in human pregnancy with subsequent child amygdala volume and affect. The results underscore the importance of the intrauterine environment and suggest the origins of neuropsychiatric disorders may have their foundations early in life.developmental programming | fetal origins | hypothalamus-pituitaryadrenal axis | depression | emotion regulation

“…Furthermore, a left central increase and a right frontal decrease in high beta band power is visible with higher valence. Especially, the frontal response might indicate a relative deactivation of cortical regions related to negative mental states [3]. Additionally, a positive correlation with right posterior gamma is observed, possibly hinting again to a role of right posterior cortices in emotion-related sensory processes.…”

Abstract. Recently, the field of automatic recognition of users' affective states has gained a great deal of attention. Automatic, implicit recognition of affective states has many applications, ranging from personalized content recommendation to automatic tutoring systems. In this work, we present some promising results of our research in classification of emotions induced by watching music videos. We show robust correlations between users' self-assessments of arousal and valence and the frequency powers of their EEG activity. We present methods for single trial classification using both EEG and peripheral physiological signals. For EEG, an average (maximum) classification rate of 55.7% (67.0%) for arousal and 58.8% (76.0%) for valence was obtained. For peripheral physiological signals, the results were 58.9% (85.5%) for arousal and 54.2% (78.5%) for valence.

“…Chimeric faces and divided visual field presentations have also largely been exploited to investigate lateralized processing of facial expressions of emotion. The amount of literature is more than abundant on this aspect and two main models have been proposed to explain emotional lateralization (see Demaree et al (2005) for a comprehensive review). The right hemisphere hypothesis posits a right-hemispheric superiority in production and perception of all emotional expressions (Campbell 1978;Ley & Bryden 1979;Levy et al 1983;Tucker et al 1995), whereas the valence hypothesis assumes a left-hemispheric superiority for the processing of positive emotions and a righthemispheric superiority for the processing of negative emotions (Reuter-Lorenz & Davidson 1981;Borod et al 1997).…”

Structural and functional asymmetries are present in many regions of the human brain responsible for motor control, sensory and cognitive functions and communication. Here, we focus on hemispheric asymmetries underlying the domain of social perception, broadly conceived as the analysis of information about other individuals based on acoustic, visual and chemical signals. By means of these cues the brain establishes the border between 'self ' and 'other', and interprets the surrounding social world in terms of the physical and behavioural characteristics of conspecifics essential for impression formation and for creating bonds and relationships. We show that, considered from the standpoint of single-and multi-modal sensory analysis, the neural substrates of the perception of voices, faces, gestures, smells and pheromones, as evidenced by modern neuroimaging techniques, are characterized by a general pattern of right-hemispheric functional asymmetry that might benefit from other aspects of hemispheric lateralization rather than constituting a true specialization for social information.
