The enzyme steroid 5α-reductase 2 (5αR2) catalyzes the conversion of testosterone into the potent androgen 5α-dihydrotestosterone. Previous investigations showed that 5αR2 is expressed in key brain areas for emotional and socio-affective reactivity, yet the role of this enzyme in behavioral regulation remains mostly unknown. Here, we profiled the behavioral characteristics of 5αR2 heterozygous (HZ) and knockout (KO) mice, as compared with their wild-type (WT) littermates. While male 5αR2 KO mice displayed no overt alterations in motoric, sensory, information-processing and anxiety-related behaviors, they exhibited deficits in neurobehavioral correlates of dominance (including aggression against intruders, mating, and tube dominance) as well as novelty-seeking and risk-taking responses...

INTRODUCTION: Successful regulation of emotional states is positively associated to mental health, while difficulties in regulating emotions are negatively associated to overall mental health and in particular associated with anxiety or depression symptoms. A key structure associated to socio-emotional regulatory processes is the central autonomic network. Activity in this structure is associated to vagal activity can be indexed noninvasively and simply by measures of peripheral cardiac autonomic modulations such as heart rate variability...

This concurrent embedded mixed methods study explored important aspects of communication occurring between military service members and their intimate partners during a combat deployment to Iraq or Afghanistan. Fifty-eight participants (32 military veterans and 26 non-veteran partners) participated in an interview using standardized self-report measures assessing the current level of relationship satisfaction, trauma symptoms of the veteran, and the veterans' trauma exposure. Participants also participated in a semistructured interview focused on combat deployment and reintegration experiences...

Emotional expressions provide strong signals in social interactions and can function as emotion inducers in a perceiver. Although speech provides one of the most important channels for human communication, its physiological correlates, such as activations of the autonomous nervous system (ANS) while listening to spoken utterances, have received far less attention than in other domains of emotion processing. Our study aimed at filling this gap by investigating autonomic activation in response to spoken utterances that were embedded into larger semantic contexts...

Basic Emotion theory has had a tremendous influence on the affective sciences, including music psychology, where most researchers have assumed that music expressivity is constrained to a limited set of basic emotions. Several scholars suggested that these constrains to musical expressivity are explained by the existence of a shared acoustic code to the expression of emotions in music and speech prosody. In this article we advocate for a shift from this focus on basic emotions to a constructionist account. This approach proposes that the phenomenon of perception of emotions in music arises from the interaction of music's ability to express core affects and the influence of top-down and contextual information in the listener's mind...

Itch is an unpleasant sensation that initiates scratching behavior. Itch-scratch reaction is a complex phenomenon whose occurrence implicates supraspinal structures required for regulation of sensory, emotional, cognitive, and motivational aspects. However, the central mechanisms underlying the processing of itch and the interplay of the supraspinal regions and spinal cord in regulating itch-scratch processes are poorly understood. Here, we have identified that the neural projections from anterior cingulate cortex (ACC) to dorsal medial striatum (DMS) constitute a critical circuit element for regulating itch-related behaviors in the brain of male C57BL/6J mice...

OBJECTIVES: In undergraduate medical education, the topics of errors in medicine and patient safety are under-represented. The aim of this study was to explore undergraduate medical students' behavioural intentions when confronted with an error. DESIGN: A qualitative case vignette survey was conducted including one of six randomly distributed case scenarios in which a hypothetical but realistic medical error occurred. The six scenarios differed regarding (1) who caused the error, (2) the presence of witnesses and (3) the consequences of the error for the patient...

The recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions (Experiment 1) as well as differently-valenced emotions (Experiment 2) conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence for a context effect on accuracy only in Experiment 1...

One of the core symptoms of borderline personality disorder (BPD) is emotion dysregulation, which comprises emotion sensitivity, heightened and labile negative affect, deficient appropriate regulation strategies, and a surplus of maladaptive regulation strategies. Although earlier studies provided some evidence for threat hypersensitivity in terms of a negatively biased perception of other people ("negativity bias") and deficits in the recognition of full-blown anger, i.e., higher error rates and slower reaction times, researchers have only recently started studying effects of interindividual differences (e...

The primary aim of this study was to investigate the effects of the 2016 United States presidential election and ensuing political climate on patients' experiences in psychotherapy. A sample of 604 self-described Democrat and Republican patients from 50 states participated in the study. Results showed that most therapists disclosed their political stance (explicitly or implicitly) and most patients discussed politics with their therapists. 64% of Clinton supporters and 38% of Trump supporters assumed political similarity with their therapist...

BACKGROUND: Children of parents with mental illness are not routinely included in psychoeducational and supportive family interventions provided by adult mental health systems. The family, therefore, is an important and, sometimes, the only source of information and support for them. AIM: To understand the experiences of well parents in talking to their children about parental mental illness. METHOD: This article presents the findings of a qualitative study of the experiences of well parents in talking to their children about parental mental illness...

Perceptions of ambiguous biological motion are modulated by different individual cognitive abilities (such as inhibition and empathy) and emotional states (such as anxiety). This study explored facing-the-viewer bias (FTV) in perceiving ambiguous directions of biological motion, and investigated whether task-irrelevant simultaneous face emotional cues in the background and the individual social anxiety traits could affect FTV. We found that facial motion cues as background affect sociobiologically relevant scenarios, including biological motion, but not non-biological situations (conveyed through random dot motion)...

Attention-deficit hyperactivity disorder (ADHD) is characterized by deficits in executive functions and decision making during childhood and adolescence. Contradictory results exist whether altered event-related potentials (ERPs) in adults are associated with the tendency of ADHD patients toward risky behavior. Clinically diagnosed ADHD patients ( n = 18) and healthy controls ( n = 18), aged between 18 and 29 (median 22 Yo), were screened with the Conners' Adult ADHD Rating Scales and assessed by the Mini-International Neuropsychiatric Interview, adult ADHD Self-Report Scale, and by the 60-item HEXACO Personality Inventory...

Yoga therapy is a newly emerging, self-regulating complementary and integrative healthcare (CIH) practice. It is growing in its professionalization, recognition and utilization with a demonstrated commitment to setting practice standards, educational and accreditation standards, and promoting research to support its efficacy for various populations and conditions. However, heterogeneity of practice, poor reporting standards, and lack of a broadly accepted understanding of the neurophysiological mechanisms involved in yoga therapy limits the structuring of testable hypotheses and clinical applications...

Depressive disorders are complex, multifactorial mental disorders with unknown neurobiology. Numerous theories aim to explain the pathophysiology. According to the "gliocentric theory", glial abnormalities are responsible for the development of the disease. The aim of this review article is to summarize the rapidly growing number of cellular and molecular evidences indicating disturbed glial functioning in depressive disorders. We focus here exclusively on the clinical studies and present the in vivo neuroimaging findings together with the postmortem molecular and histopathological data...

Generalization of learned fear has been considered to be critical for our survival. Patients with anxiety problems show overgeneralization of learned fear, as reflected by defensive physiological responses to harmless stimuli. Together with these physiological responses, conscious feeling of fear is a seminal part of emotional process that is directly related to the suffering of anxiety patients. However, the effect of anxiety on the generalization of conscious feeling remains unclear. We thus focused on the question whether the generalization of conscious feeling of fear depends on individual anxiety level in nonpatient participants...

The dorsal anterior cingulate cortex (dACC) has been identified as a core region affected by many disorders, representing a promising target for neuromodulation. High Definition-transcranial Direct Current Stimulation (HD-tDCS) is a non-invasive neuromodulation technique that has already shown promising outcomes and has been tested to engage deeper structures. This study investigates whether it is possible to modulate dACC activity using anodal and cathodal HD-tDCS. Furthermore, it examines what effects anodal and cathodal HD-tDCS targeting dACC have on cognitive and emotional processing...

BACKGROUND: Research suggests that individuals with anxiety have difficulty ignoring threat distractors when completing tasks with competing stimuli. Studies examining the neural correlates of these emotional processing difficulties in youth anxiety highlight reduced recruitment of regions associated with goal-directed attention, such as the anterior cingulate cortex (ACC). In the current study, we examined neural activation during an emotional conflict task in youth with anxiety disorders before and after treatment...

The etiology of depression is characterized by the interplay of genetic and environmental factors and brain structural alteration. Childhood adversity is a major contributing factor in the development of depression. Interactions between childhood adversity and candidate genes for depression could affect brain morphology via the modulation of neurotrophic factors, serotonergic neurotransmission, or the hypothalamus-pituitary-adrenal (HPA) axis, and this pathway may explain the subsequent onset of depression...
