Cataplexy is a hallmark of narcolepsy characterized by the sudden uncontrollable onset of muscle weakness or paralysis during wakefulness. It can occur spontaneously, but is typically triggered by positive emotions such as laughter. Although cataplexy was identified over 130 years ago, its neural mechanism remains unclear. Here, we show that a newly identified GABA circuit within the central nucleus of the amygdala (CeA) promotes cataplexy. We used behavioral, electrophysiological, immunohistochemical, and chemogenetic strategies to selectively target and manipulate CeA activity in narcoleptic (orexin(-/-) ) mice to determine its functional role in controlling cataplexy...

Emotion experience and regulation frequently occur in social settings. Social influence is a common source of unconscious change in judgment in many contexts, but it has yet to be investigated as a form of automatic emotion regulation. Here, we demonstrate that nonpredictive social information (i.e., high or low "emotion intensity ratings from other people" that were not related to the actual intensity of the pictures) about the intensity of pleasant and unpleasant picture stimuli can influence self-reported emotional experience and the magnitude of the late positive potential, an event-related potential associated with the detection of emotional salience and sustained attention to motivationally significant stimulus features...

Distinguishing bipolar disorder from major depressive disorder is a major challenge in psychiatric treatment. Consequently, there has been growing interest in identifying neuronal biomarkers of disorder-specific pathophysiological processes to differentiate affective disorders. Thirty-six depressed bipolar patients, 36 depressed unipolar patients and 36 matched healthy controls participated in an fMRI-experiment. Emotional faces served as stimuli in a matching task. We investigated neural activation towards angry, fearful and happy faces focusing on prototypical regions related to emotion processing, ie the amygdala and the anterior cingulate gyrus (ACG)...

Financial risky decisions and evaluations pervade many human everyday activities. Scientific research in such decision-making typically explores the influence of socio-economic and cognitive factors on financial behavior. However, very little research has explored the holistic influence of contextual, emotional, and hormonal factors on preferences for risk in insurance and investment behaviors. Accordingly, the goal of this review article is to address the complexity of individual risky behavior and its underlying psychological factors, as well as to critically examine current regulations on financial behavior...

A single nucleotide polymorphism of rs1360780 in the FKBP5 gene is associated with a predisposition to developing major depressive disorder (MDD). We investigated the interactive effects of FKBP5 rs1360780 allelic variants, DNA methylation, and the diagnosis of MDD on structural changes of the entire brain. One hundred and fourteen patients with MDD and eighty-eight healthy controls underwent T1-weighted structural magnetic resonance imaging and FKBP5 rs1360780 genotyping, including DNA methylation of intron 7...

Reappraisal is a particularly effective strategy for influencing emotional experiences, specifically for reducing the impact of negative stimuli. Although depression has repeatedly been linked to dysfunctional behavioral and neural emotion regulation, prefrontal and amygdala engagement seems to vary with clinical characteristics and the specific regulation strategy used. Whereas previous neuroimaging research has focused on down-regulating reactions to emotionally evocative scenes, the current study compared up- and down-regulation in response to angry facial expressions in patients with depression and healthy individuals...

Though the spontaneous emotion regulation has received long discussions, few studies have explored the regulatory effects of spontaneous expressive suppression in neural activations, especially in collectivistic cultural context. The functional magnetic resonance imaging (fMRI) study aimed to examine whether individual differences in the tendency to use suppression are correlated with amygdala responses to negative situations when individuals are unconsciously primed with expressive suppression. Twenty-three healthy Chinese undergraduates completed an fMRI paradigm involving fear processing, and a synonym matching task was added to prime participants with the unconscious (automatic) expressive suppression goal...

In Canada, little is known about how food parenting practices are associated with young children's dietary intakes and no studies have examined food parenting practices of Canadian fathers. This study aimed to examine associations between food parenting practices and preschool-age children's nutrition risk. We conducted a cross-sectional analysis of 31 two-parent families; 31 mothers, 31 fathers and 40 preschool-age children. Parents completed an adapted version of the Comprehensive Feeding Practices Questionnaire...

Research investigating the effects of trauma exposure on brain structure and function in adults has mainly focused on post-traumatic stress disorder (PTSD), whereas trauma-exposed individuals without a clinical diagnoses often serve as controls. However, this assumes a dichotomy between clinical and subclinical populations that may not be supported at the neural level. In the current study we investigate whether the effects of repeated or long-term stress exposure on brain structure in a subclinical sample are similar to previous PTSD neuroimaging findings...

Research on executive control during the teenage years points to shortfalls in emotion regulation, coping, and decision making as three linked capabilities associated with youth's externalizing behavior problems. Evidence gleaned from a detailed review of the literature makes clear that improvement of all three capabilities is critical to help young people better navigate challenges and prevent or reduce externalizing and related problems. Moreover, interventions can successfully improve these three capabilities and have been found to produce behavioral improvements with real-world significance...

Attachment-based theories and related research illustrate that emotion regulation develops in the context of a secure relationship between a child and caregiver. When a secure bond is broken, such as in the context of betrayal trauma, children fail to develop necessary emotion regulation skills which can lead to an array of relational problems. The current study examined the relations between betrayal trauma history, type of communication during a stressful interpersonal laboratory task, and emotion regulation difficulties in a sample of trauma-exposed adolescents...

We investigated links between temperament traits described in Strelau's Regulative Theory of Temperament (Emotional Reactivity, Briskness, Activity, Endurance, Perseveration and Sensory Sensitivity) and subjective well-being (SWB)-Positive Affect, Negative Affect and Life Satisfaction as conceptualised by Diener. Participants representing early (n = 166) and late adolescence (n = 199), early (n = 195) and mid-adulthood (n = 156) filled out Formal Characteristics of Behaviour-Temperament Inventory, Positive and Negative Affect Schedule and Satisfaction with Life Scale...

A brain network comprising the medial prefrontal cortex (mPFC) and amygdala plays important roles in developmentally-regulated cognitive and emotional processes. However, very little is known about the maturation of mPFC-amygdala circuitry. We conducted anatomical tracing of mPFC projections and optogenetic interrogation of their synaptic connections with neurons in the basolateral amygdala (BLA) at neonatal to adult developmental stages in mice. Results indicate that mPFC-BLA projections exhibit delayed emergence relative to other mPFC pathways and establish synaptic transmission with BLA excitatory and inhibitory neurons in late infancy, events which coincide with a massive increase in overall synaptic drive...

There is evidence that the neural mechanisms underlying Internet Gaming Disorder (IGD) resemble those of drug addiction. Functional Magnetic Resonance Imaging (fMRI) studies of the resting state and measures of gray matter volume have shown that Internet game playing was associated with changes to brain regions responsible for attention and control, impulse control, motor function, emotional regulation, sensory-motor coordination. Furthermore, Internet game playing was associated with lower white matter density in brain regions that are involved in decision-making, behavioral inhibition and emotional regulation...

The importance of reappraising negative events to reduce negative emotional responses has been widely acknowledged. However, most neuroimaging studies have explored the neural mechanisms of deliberate and intentional reappraisal, while little is known about the neural correlates of reappraisal that occurs outside of one's awareness. Electrophysiological studies suggest that precedent neutral descriptions could implicitly reduce neural responses to unpleasant images. To investigate the neural mechanism underlying implicit reappraisal, functional magnetic resonance imaging was conducted on 25 participants while they passively viewed unpleasant images that were previously neutrally/positively or negatively described...

INTRODUCTION: Emotion regulation is an important everyday-life skill to reduce harm and stress. Consequently, research shows associations between psychopathologies and emotional dysregulation. The serotonin transporter polymorphism (5-HTTLPR) has repeatedly been associated to phenotypes and syndromes related to emotional dysregulation. However, there is no study showing any direct effects of 5-HTTLPR genotype and emotion regulation. Hence, the aim of the present study was to draw a link between 5-HTTLPR to emotion regulation...

Prior research has linked marital conflict to children's internalizing/externalizing disorders, insecure attachment, and poor emotional regulation (e.g., Cummings & Davies, 2010; Cummings, Iannotti, & Zahn-Waxler, 1985). Although investigators have examined the impact of marital discord on older children (e.g., Crockenberg & Langrock, 2001), few have explored direct links in infancy (e.g., Cowan & Cowan, 1999). This study extends earlier work by examining linkages between marital functioning (conflict and harmony) and infants' cardiac vagal tone and developmental status across 2 time points using a cross-lag approach...

Individuals with aggression regulation disorders tend to attribute hostility to others in socially ambiguous situations. Previous research suggests that this "hostile attribution bias" is a powerful cause of aggression. Facial expressions form important cues in the appreciation of others' intentions. Furthermore, accurate processing of facial expressions is fundamental to normal socialization. However, research on interpretation biases in facial affect is limited. It is asserted that a hostile interpretation bias (HIB) is likely to be displayed by individuals with an antisocial (ASPD) and borderline personality disorder (BPD) and probably also with an intermittent explosive disorder (IED)...

Calculating math problems from memory may seem unrelated to everyday processing of emotions, but they have more in common than one might think. Prior research highlights the importance of the dorsolateral prefrontal cortex (dlPFC) in executive control, intentional emotion regulation, and experience of dysfunctional mood and anxiety. While it has been hypothesized that emotion regulation may be related to 'cold' (ie. not emotion-related) executive control, this assertion has not been tested. We address this gap by providing evidence that greater dlPFC activity during 'cold' executive control is associated with increased use of cognitive reappraisal to regulate emotions in everyday life...
