EDITORIAL
Julia F Christensen, Antoni Gomila
Empirical aesthetics in general, and neuroaesthetics in particular, have been very much influenced by Berlyne's psychobiological program. For him, aesthetic appreciation involved the brain's reward and aversion systems. From this point of view, art constitutes a set of potentially rewarding stimuli. Research has certainly made great advances in understanding how the process of artistic valuation takes places, and which brain circuits are involved in generating the pleasure we obtain from artistic practices, performances, and works...

In the last decades, psychoneuroendocrineimmunology research has made relevant contributions to the fields of neuroscience, psychobiology, epigenetics, molecular biology, and clinical research by studying the effect of stress on human health and highlighting the close interrelations between psyche, brain, and bodily systems. It is now well recognized that chronic stress can alter the physiological cross-talk between brain and biological systems, leading to long-lasting maladaptive effects (allostatic overload) on the nervous, immune, endocrine, and metabolic systems, which compromises stress resiliency and health...

Depression is the leading cause of disability worldwide, and its prevalence is 2 times higher in women than in men. There is, however, a lack of data on sex-specific pathophysiology of this disorder. The purpose of this systematic review is to identify the biological sex differences found in major depressive disorder (MDD) in studies published in the last 10 years. We conducted a literature search using the Medline, PsycInfo, PubMed, and Web of Science databases, selecting English-language studies that included physiological measures compared by sex in addition to MDD...

Worldwide, psychological and social issues in cancer were not the subject of scientific inquiry until the past two decades. Since then, a new subspecialty of oncology has evolved, psycho-oncology. It addresses two dimensions of cancer: the emotional responses of patients at all stages of disease, as well as their families and caretakers (psychosocial); and the pyschological, social and behavioral factors that may influence cancer morbidity and mortality (psychobiological). Obstacles to development have been the facts of small numbers of clinicians and investigators worldwide and the few valid assessment instruments and research methods available to the biomedical community...

Binge drinking (BD), i.e., consuming a large amount of alcohol in a short period of time, is an increasing public health issue. Though no clear definition has been adopted worldwide the speed of drinking seems to be a keystone of this behavior. Developing relevant animal models of BD is a priority for gaining a better characterization of the neurobiological and psychobiological mechanisms underlying this dangerous and harmful behavior. Until recently, preclinical research on BD has been conducted mostly using forced administration of alcohol, but more recent studies used scheduled access to alcohol, to model more voluntary excessive intakes, and to achieve signs of intoxications that mimic the human behavior...

STUDY OBJECTIVES: According to the diathesis-stress model of insomnia, insomnia may develop in vulnerable individuals in response to stress. Resilience is a psychobiological factor that determines an individual's capacity to adapt successfully to stressful events and low resilience increases vulnerability for development of mental disorders. The aim was to explore resilience in subjects with insomnia and its relationship with the factors that contribute to its development and perpetuation...

The origin of the sense of effort has been debated for several decades and there is still no consensus among researchers regarding the underlying neural mechanisms. Some advocate that effort perception mainly arises from an efference copy originating within the brain while others believe that it is predominantly carried by muscle afferent signals. To move the debate forward, we here tested the hypothesis that there is not one but several senses of effort which depend on the way it is evaluated. For this purpose, we used two different psychophysical tests designed to test effort perception in elbow flexors...

INTRODUCTION: The prevalence of postnatal depression (PND) is significant: reaching up to 20% in the general population. In mechanistic terms, the risk of PND lies in an interaction between a maternal psychophysiological vulnerability and a chronic environmental context of stress. On the one hand, repetition of stressor during pregnancy mimics a chronic stress model that is relevant to the study of the allostatic load and the adaptive mechanisms. On the other hand, vulnerability factors reflect a psychological profile mirroring mindfulness functioning (psychological quality that involves bringing one's complete and non-judgemental attention to the present experience on a moment-to-moment basis)...

PURPOSE OF REVIEW: This review focuses on the relationship between resilience and the ability to effectively modulate the stress response. Neurobiological and behavioral responses to stress are highly variable. Exposure to a similar stressor can lead to heterogeneous outcomes-manifesting psychopathology in one individual, but having minimal effect, or even enhancing resilience, in another. We highlight aspects of stress response modulation related to early life development and epigenetics, selected neurobiological and neurochemical systems, and a number of emotional, cognitive, psychosocial, and behavioral factors important in resilience...

The objective of this study was to use the Biobehavioral Family Model (BBFM) to delineate which psychophysiological variables link romantic and family relationship satisfaction variables to health outcomes. Data from individuals who reported being partnered from the second wave of the National Survey of Midlife Development in the United States (MIDUS II), Project 4 (n = 812) were used to test a structural equation model which explored which psychophysiological variables potentially mediated associations between positive and negative family emotional climate variables and disease activity...

PURPOSE OF REVIEW: The review examines the different preventive measures that have been found to be useful to abolish or decrease the negative effects of burnout and increase resilience in anesthesiologists. RECENT FINDINGS: Studies in anesthesiology cite autonomy, control of the work environment, professional relationships, leadership, and organizational justice as the most important factors in job satisfaction. Factors such as difficulty in balancing personal and professional life, poor attention to wellness, work alcoholism, and genetic factors increase an individual's susceptibility to burnout...

OBJECTIVE: Research on psychobiological markers of Parkinson's disease (PD) remains a hot topic. Non-motor symptoms such as depression and REM sleep behavior disorder (RBD) each attribute to a particular neurodegenerative cluster in PD, and might enlighten the way for early prediction/detection of PD. The neuropathology of mood disturbances remains unclear. In fact, a few studies have investigated depression using diffusion magnetic resonance imaging (diffusion MRI). METHOD: Diffusion MRI of PD patients without comorbid RBD was used to assess whether microstructural abnormalities are detectable in the brain of 40 PD patients with depression compared to 19 patients without depression...

Andrew C Parrott
Many novel psychoactive substances (NPS) have entered the recreational drug scene in recent years, yet the problems they cause are similar to those found with established drugs. This article will debate the psychobiological effects of these newer and more traditional substances. It will show how they disrupt the same core psychobiological functions, so damaging well-being in similar ways. Every psychoactive drug causes mood states to fluctuate. Users feel better on-drug, then feel worse off-drug. The strength of these mood fluctuations is closely related to their addiction potential...

Background and objective: Psychological states may interfere with visceral sensitivity. Here we investigate associations between psychosocial factors and visceral sensitivity in irritable bowel syndrome (IBS). Methods: Two IBS patient cohorts (Cohort 1: n  = 231, Rome II; Cohort 2: n  = 141, Rome III) underwent rectal barostat testing, and completed questionnaires for anxiety, depression, somatization, and abuse. The associations between questionnaire measures and visceral sensitivity parameters were analyzed in three-step general linear models (step1: demographic and abuse variables; step 2: anxiety and depression; step 3: somatization)...

Throughout the last 2500 years, the classification of individual differences in healthy people and their extreme expressions in mental disorders has remained one of the most difficult challenges in science that affects our ability to explore individuals' functioning, underlying psychobiological processes and pathways of development. To facilitate analyses of the principles required for studying individual differences, this theme issue brought together prominent scholars from diverse backgrounds of which many bring unique combinations of cross-disciplinary experiences and perspectives that help establish connections and promote exchange across disciplines...

Psychodynamic psychiatry is not limited to psychotherapy practice. It is defined by systematic attention to the "common factors" underlying both psychotherapy and psychopharmacology outcomes, which include the patient's subjective systems of meaning and the complex flow of the patient-provider relationship in addition to the patient's "objective" psychopathology. It allows for a non-reductionist milieu where the meaning of the illness and the full complexity of the treatment process can be explored in order to achieve a qualitative and lasting change in the patient's psychopathology...

Psychological resources and risk factors influence risk of coronary heart disease. We evaluated whether inverted items in the Self-esteem, Mastery, and Center for Epidemiological Studies Depression scales compromise validity in the context of coronary heart disease. In a population-based sample, validity was investigated by calculating correlations with other scales ( n  = 1004) and interleukin-6 ( n  = 374), and by analyzing the relationship with 8-year coronary heart disease risk ( n  = 1000)...

BACKGROUND: Anxiety and depression have been linked to repetitive negative self-regulation styles in the form of worry and rumination respectively. Following predictions of the metacognitive model [Wells, A., & Matthews, G. (1994). Attention and emotion: A clinical perspective. Hove: Erlbaum], the current study compared the effect on recovery from stress of three strategies: worry, rumination, and distraction using a stress exposure paradigm. It was predicted that worry and/or rumination would be associated with delayed recovery on physiological and/or self-report indices when compared to distraction...

The placebo-effect is present in almost every field of medicine, however, in the assessment of the effect of psychotropic drugs it is a major problem. The rise of the placebo-effect in clinical trials is observed during the last decades, in spite of all efforts to introduce new methods in clinical trials to overcome this problem and the number of studies aiming to unveil the mechanisms that lie in the background that this phenomenon have risen. A considerable amount of data has accumulated regarding the psychobiological background of placeboeffect, however, the details of underlying mechanisms are still not clear...

Psychobiological research has generated a tremendous amount of findings on the psychological, neuroendocrine, molecular and environmental processes that are directly relevant for mental and physical health, but have overwhelmed our capacity to meaningfully absorb, integrate, and utilize this knowledge base. Here, we reflect about suitable strategies to improve the translational success of psychoneuroendocrinological research in the era of precision medicine. Following a strategy advocated by the National Research Council and the tradition of endophenotype-based research, we advance here a new approach, termed "conceptual endophenotypes"...
