Abstract

Physical activity and exercise were receiving a great attention as a strategy of prevention and treatment of affective and some anxiety disorders. Many studies have showed the efficacy of exercise in major depression and at depressed episode of bipolar patients, as well as, some authors shows the benefits of exercise in some anxiety disorders like Generalized Anxiety Disorder and Panic. Despite their efficacy, little is known concerning the main mechanisms related to the antidepressant and anxiolytic effects of exercise. Several studies in an animal model using Neurotrophic Factors, Oxidative Stress, Immunologic response and other biological markers reveal promising results. However, few studies were conducted in clinical samples. Additional to the antidepressant and anxiolytic effects, exercise appears improve QoL in major depressed, bipolar and anxiety patients. Theoretically, this increase may be associated with cognitive improvements, improvements at sleep quality, physical functioning, as well as other psychological issues as self-esteem, self-concept, and general well-being. The propose of this topic is to address the novelty and most recent research, related to antidepressant and anxiolytic effects of physical activity and exercise in patients with affective and anxiety disorders, as well as the issues associated with QoL improvement.The topic is looking for: – Clinical trials using exercise and physical activity as a treatment affective and anxiety disorders. – Studies investigating the optimal prescription factors (dose, volume, intensity, setting, frequency) associated with antidepressant and anxiolytic effects of physical activity and exercise for affective and anxiety disorder patients. – Original studies, comprehensive reviews, hypothesis and opinions concerning the mechanisms of antidepressant and anxiolytic effects of physical activity and exercise in affective and anxiety disorder patients. – Original studies, comprehensive reviews, hypothesis and opinions concerning other benefits of physical activity and exercise like : cognition, weight gain prevention and QoL in affective and anxiety disorder patients. – Translational research. – Studies of cost-efficacy analysis

Abstract

Attentional biases (ABs) play a prominent role in the development and maintenance of clinically relevant symptoms of, for example, anxiety and depression. In particular, increased attentional orienting and preoccupation with biologically relevant and mood-congruent stimuli has been observed, suggesting that the visual-attentional system is overly sensitive towards threat cues and avoidant of cues of reward in these disorders. First, several experimental paradigms have been used to assess ABs, e.g., the dot probe task, the emotional stroop task, and the spatial cueing task amongst others. Yet, these paradigms are based on different theoretical backgrounds and target different stages of the attentional process. Thus, different paradigms provided converging as well as diverging evidence with regard to ABs. However, it is often not entirely clear to what extent this reflects real differences and commonalities, or is caused by differences in methodology. For example, behavioral reaction time data can only provide a snapshot of selective attention. Measuring event-related potentials, eye movements, or functional brain imaging data enables exploring the exact temporal and spatial dynamics of attentional processes. Moreover, neuroimaging data reveal specific cortical networks involved in directing attention toward a stimulus or disengaging from it. Second, ABs have been mainly discussed as symptoms of psychopathology, while results in healthy participants are still scarce; previous studies mostly compared extreme groups. However, a comprehensive theoretical and empirical account of ABs in psychopathology also requires a thorough account of ABs in the general healthy population. Moreover, the effect of gender, as an important contributing factor in processing of emotional stimuli, has also not been considered systematically in previous research. Third, a variety of stimuli has been used in the assessment of ABs. So far, mostly facial or word stimuli have been applied. However, in everyday life not only facial emotion recognition but also a fast evaluation of complex social situations is important to be effective in social interactions. Recent research started using more complex stimuli to raise ecological validity. However, the use of ecologically valid stimuli poses some methodological challenges and needs to be applied more systematically. The aim of this research topic is to integrate different paradigms and stimuli, addressing individuals from the whole range of the population continuum, and to apply different methodological approaches. It is intended to bring together expertise in stimulus selection, timing and implementing issues, advancing and broadening the overall understanding of ABs.

Abstract

We rely heavily on faces during social interactions. Humans possess the ability to recognise thousands of people very quickly and accurately without effort. The serious social difficulties that follow abnormalities of the face recognition system (i.e., prosopagnosia) strongly underline the importance of typical face skills in our everyday life. Over the last fifty years, research on prosopagnosia, along with research in the healthy population, has provided insights into the cognitive and neural features behind typical face recognition. This has also been achieved thanks to non-invasive neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI), Electroencephalography (EEG), Magnetoencephalography (MEG), Diffusion Tensor Imaging (DTI) and Transcranial Magnetic Stimulation (TMS). However, there is still much debate about the cognitive and neural mechanisms of face perception. In the current Research Topic we plan to gather experimental works, opinions, commentaries, mini-reviews and reviews that focus on new or novel theories and methods in face perception research. Where is the field at the moment? Do we need to re-think the experimental procedures we have adopted so far? Again, what kind of techniques (or combination of them) and analysis methods will be important in the future? From the experimental point of view we encourage both behavioural and neuroimaging contributions (e.g., fMRI, EEG, MEG, DTI and TMS). Despite the main emphasis on face perception, memory and identification, we will also consider original works that focus on other aspects of face processing, such as expression recognition, attractiveness judgments and face imagery. In addition, animal investigations and experimental manipulations that alter face recognition abilities in typical human subjects (e.g., hypnosis) are also welcome. Overall, we are proposing a Research Topic that looks at face processing using different perspectives and welcome contributions from different domains such as psychology, neurology, neuroscience, cognitive science and philosophy. The current Research Topic evolved over the desire to acknowledge the relatively recent loss of three giants in the field: Drs. Shlomo Bentin, Truett Allison and Andy Calder. We dedicate this Research Topic to them and their pioneering studies.

Abstract

Traditionally, abnormalities of neurons and neuronal networks including synaptic abnormalities and disturbance of neurotransmitters have dominantly been believed to be the main causes of psychiatric disorders. Recent cellular neuroscience has revealed various unknown roles of glial cells such as astrocytes, oligodendrocytes and microglia. These glial cells have proved to continuously contact with neurons /synapses, and have been shown to play important roles in brain development, homeostasis and various brain functions. Beyond the classic neuronal doctrine, accumulating evidence has suggested that abnormalities and disturbances of neuron-glia crosstalk may induce psychiatric disorders, while these mechanisms have not been well understood. This Research Topic of the Frontiers in Cellular Neuroscience will focus on the most recent developments and ideas in the study of glial cells (astrocytes, oligodendrocytes and microglia) focusing on psychiatric disorders such as schizophrenia, mood disorders and autism. Not only molecular, cellular and pharmacological approaches using in vitro / in vivo experimental methods but also translational research approaches are welcome. Novel translational research approaches, for example, using novel techniques such as induced pluripotent stem (iPS) cells, may lead to novel solutions. We believe that investigations to clarify the correlation between glial cells and psychiatric disorders contribute to a novel understanding of the pathophysiology of these disorders and the development of effective treatment strategies.

Abstract

The discovery of the involvement of neuropeptides with behaviours other than regulatory motivated ones took place in the midst of 1960’s with David de Wied’s first report on the influence of pituitary peptides on memory. This major scientific breakthrough opened a new frontier of studies in Endocrinology and its related fields, Neuroendocrinology and Psychoneuroendocrinology. Neuropeptides were initially thought to be involved in homeostatic regulation and secreted only from neurons located in the hypothalamus; they are now recognized neurotransmitters, produced in and secreted from distinct brain areas, associated with a myriad of, not only, motivated, but also psychopathological behaviours. Motivated behaviours are determinant for individual and species survival, but their expression in a large spectrum and deviations from average may give rise to a number of psychiatric conditions.

Abstract

Perseverative cognition is defined as the repetitive or sustained activation of cognitive representations of past stressful events or feared events in the future and even at non-clinical levels it causes a “fight-or-flight” action tendency, followed by a cascade of biological events, starting in the brain and ending as peripheral stress responses. In the past decade, such persistent physiological activation has proven to impact individuals’ health, potentially leading to somatic disease. As such, perseverative cognition has recently been proposed as the missing piece in the relationships between stress, psychopathology, and risk for health. Perseverative cognition is indeed a hallmark of conditions such as anxiety and mood disorders that are at increased -though still unexplained- cardiovascular risk. Although the pivotal role of ruminative and worrisome thoughts in determining the onset and maintenance of psychopathological disorders has been acknowledged for a long time, its effects on the body via reciprocal influences between mental processes and the body's physiology have been neglected. Moreover, perseverative cognition is definitely not restricted to psychopathology, it is extremely common and likely even omnipresent, pervading daily life. The objective of the Research Topic is to provide an interdisciplinary examination of cutting-edge neuroscientific research on brain-body signatures of perseverative cognition in both healthy and psychopathological individuals. Despite the evident role of the brain in repetitive thinking and the assumption that our mind is embodied, bran-body pathways from perseverative cognition to health risk have remained largely unexplored.

Abstract

Statistically, women appear to suffer more frequently from depressive and anxiety disorders, featuring more regularly in primary care figures for consultations, diagnoses and prescriptions for psychotropic medication. This has been consistently so throughout the post-war period with current figures suggesting that women are approximately twice more likely to suffer from affective disorders than men. However, this book suggests that the statistical landscape reveals only part of the story. Currently, 75 per cent of suicides are among men, and this trend can also be traced back historically to data that suggests this has been the case since the beginning of the twentieth-century. This book suggests that male psychological illness was in fact no less common, but that it emerged in complex ways and was understood differently in response to prevailing cultural and medical forces. The book explores a host of medical, cultural and social factors that raise important questions about historical and current perceptions of gender and mental illness.
