“…Interestingly, for fearful stimuli, differences were almost absent, showing a slight deactivation increase in the right visual cortex in subjects with ASDs compared to typical controls. Some investigators (Morris et al 1998(Morris et al , 1999Nomura et al 2004;Best et al 1994;Davidson and Irwin 1999) have reported right hemispheric dominance concerning unconscious negative emotional processing, although recent studies of emotional valence have failed to detect hemispheric dominance (Viinikainen et al 2010). Sato and Aoki (2006) have speculated that right hemispheric dominance in unconscious negative emotional processing may not be specific to facial stimuli.…”

FMRI was performed with the dynamic facial expressions fear and happiness. This was done to detect differences in valence processing between 25 subjects with autism spectrum disorders (ASDs) and 27 typically developing controls. Valence scaling was abnormal in ASDs. Positive valence induces lower deactivation and abnormally strong activity in ASD in multiple regions. Negative valence increased deactivation in visual areas in subjects with ASDs. The most marked differences between valences focus on fronto-insular and temporal regions. This supports the idea that subjects with ASDs may have difficulty in passive processing of the salience and mirroring of expressions. When the valence scaling of brain activity fails, in contrast to controls, these areas activate and/or deactivate inappropriately during facial stimuli presented dynamically.

Emotion plays a significant role in goal-directed behavior, yet its neural basis is yet poorly understood. In several psychological models the cardinal dimensions that characterize the emotion space are considered to be valence and arousal. Here 3T functional magnetic resonance imaging (fMRI) was used to reveal brain areas that show valence- and arousal-dependent blood oxygen level dependent (BOLD) signal responses. Seventeen healthy adults viewed pictures from the International Affective Picture System (IAPS) for brief 100 ms periods in a block design paradigm. In many brain regions BOLD signals correlated significantly positively with valence ratings of unpleasant pictures. Interestingly, partly in the same regions but also in several other regions BOLD signals correlated negatively with valence ratings of pleasant pictures. Therefore, there were several areas where the correlation across all pictures was of inverted U-shape. Such correlations were found bilaterally in the dorsolateral prefrontal cortex (DLPFC), dorsomedial prefrontal cortex (DMPFC) extending to anterior cingulate cortex (ACC), and insula. Self-rated arousal of those pictures which were evaluated to be unpleasant correlated with BOLD signal in the ACC, whereas for pleasant pictures arousal correlated positively with the BOLD signal strength in the right substantia innominata. We interpret our results to suggest a major division of brain mechanisms underlying affective behavior to those evaluating stimuli to be pleasant or unpleasant. This is consistent with the basic division of behavior to approach and withdrawal, where differentiation of hostile and hospitable stimuli is crucial.

“…No medication, except birth-control pills, was allowed. Psychiatric disorders were excluded using the Mini-International Neuropsychiatric Interview (Mini [52]) and the Dutch translation of the Beck Depression inventory (BDI [7]). Female volunteers with a psychiatric disorder and/or a score higher than eight on the BDI were excluded.…”

Repetitive Transcranial Magnetic Stimulation (rTMS) studies investigating brain imaging correlates of emotion modulation in healthy volunteers can improve our understanding of the 'affective' impact of this application. In this fMRI study, we focused on lateralized amygdala functioning when processing salient emotional visual stimuli after one high-frequency (HF)-rTMS session. In a 'uniform sample' of 20 right-handed, non-depressed, healthy female subjects we examined whether one HF-rTMS session applied to the left (n=10) or right (n=10) dorsolateral prefrontal cortex (DLPFC) would influence amygdala responses to positively and negatively valenced baby faces. Subjects were given no other instructions than to focus on the emotion the visual stimuli elicited during scanning. One HF-rTMS session did not result in a conscious mood change. Whereas one left-sided HF-rTMS session did not affect amygdala processing of the positive or negative stimuli, after a single rightsided HF-rTMS session we found a significant right amygdala activity attenuation during the processing of negatively valenced baby faces. This finding provides additional evidence supporting the role of the right anterior hemisphere in the processing of negative emotional information, and increases our understanding of HF-rTMS treatment effects in mental disorders.3
