Neurosurgical treatment of psychiatric disorders has been influenced by evolving neurobiological models of symptom generation. The advent of functional neuroimaging and advances in the neurosciences have revolutionized understanding of the functional neuroanatomy of psychiatric disorders. This article reviews neuroimaging studies of depression from the last 3 decades and describes an emerging neurocircuitry model of mood disorders, focusing on critical circuits of cognition and emotion, particularly those networks involved in the regulation of evaluative, expressive and experiential aspects of emotion. The relevance of this model for neurotherapeutics is discussed, as well as the role of functional neuroimaging of psychiatric disorders.

Reliable individual differences in electrophysiological measures of prefrontal activation asymmetry exist and predict dispositional mood and other psychological and biological indices of affective style. Subjects with greater relative right-sided activation report more dispositional negative affect and react with greater intensity to negative emotional challenges than their left-activated counterparts. We previously established that such individual differences in measures of prefrontal activation asymmetry were related to basal NK function, with left-activated subjects exhibiting higher levels of NK function than right-activated subjects. The present study was designed to replicate and extend these earlier findings. Subjects were tested in five experimental sessions over the course of 1 year. During the first two sessions, baseline measures of brain electrical activity were obtained to derive indices of asymmetric activation. During sessions 3 and 4, blood samples were taken during a nonstressful period in the semester and then 24 h prior to the subjects' most important final examination. During session 5, subjects were presented with positive and negative film clips 30 min in duration. Blood samples were obtained before and after the film clips. Subjects with greater relative right-sided activation at baseline showed lower levels of basal NK function. They also showed a greater decrease in NK function during the final exam period compared to the baseline period. Subjects with greater relative left-sided activation showed a larger increase in NK function from before to after the positive film clip. These findings indicate that individual differences in electrophysiological measures of asymmetric prefrontal activation account for a significant portion of variance in both basal levels of, and change in NK function.

<p>Making Sense of Tantric Buddhism fundamentally rethinks the nature of the transgressive theories and practices of the Buddhist Tantric traditions, challenging the notion that the Tantras were "marginal" or primitive and situating them instead -- both ideologically and institutionally -- within larger trends in mainstream Buddhist and Indian culture. Critically surveying prior scholarship, Wedemeyer exposes the fallacies of attributing Tantric transgression to either the passions of lusty monks, primitive tribal rites, or slavish imitation of Saiva traditions. Through comparative analysis of modern historical narratives -- that depict Tantrism as a degenerate form of Buddhism, a primal religious undercurrent, or medieval ritualism -- he likewise demonstrates these to be stock patterns in the European historical imagination. Through close analysis of primary sources, Wedemeyer reveals the lived world of Tantric Buddhism as largely continuous with the Indian religious mainstream and deploys contemporary methods of semiotic and structural analysis to make sense of its seemingly repellent and immoral injunctions. Innovative, semiological readings of the influential Guhyasamaja Tantra underscore the text's overriding concern with purity, pollution, and transcendent insight -- issues shared by all Indic religions -- and a large-scale, quantitative study of Tantric literature shows its radical antinomianism to be a highly managed ritual observance restricted to a sacerdotal elite. These insights into Tantric scripture and ritual clarify the continuities between South Asian Tantrism and broader currents in Indian religion, illustrating how thoroughly these "radical" communities were integrated into the intellectual, institutional, and social structures of South Asian Buddhism.</p>

<p>This position paper advocates for early childhood teachers and parents to regularly use of mindfulness practices themselves and with very young children. An understanding of 'mindfulness' is important because it can provide ways to support children during their sensitive years and sow seeds of kindness, tolerance and peace in our fast paced, competitive, consumerist culture. In addition, in times of trauma, mindfulness techniques offer teachers and parents ways to calm themselves and the children close to them. The value of using mindfulness techniques with children and for demonstrating mindfulness as adults is well supported by research (McCown, Reibel and Micozzi, 2010; Saltzman and Goldin, 2008).</p>

Mystical texts and the visual arts have contributed immeasurably to shaping individual and collective conceptions of the spiritual in modern and postmodern culture. By integrating rigorous textual analysis with direct experiential practices, we will bring a multifaceted approach to bear on the relationship between aesthetic, intellectual and mystical creativity—that is, between the often conflicting domains of spiritual experience, intellectual analysis, and beauty—in order to gain insight into the ways in which these distinctive yet overlapping modalities of knowledge have integrally shaped developments in high culture, sacred practice and visual representation. Drawing on the combined methodological perspectives of Art History and Religious Studies, we will examine the ways in which the contemplative and experiential practices of museum viewing, ritual performances, trans-cultural encounter and focused reading and writing activities can all serve as powerful acts of human self-creation.

Past studies have documented interpersonal benefits of natural environments. Across four studies, we tested the hypothesis that exposure to more beautiful nature, relative to less beautiful nature, increases prosocial behavior. Study 1 yielded correlational evidence indicating that participants prone to perceiving natural beauty reported greater prosocial tendencies, as measured by agreeableness, perspective taking, and empathy. In Studies 2 and 3, exposure to more beautiful images of nature (versus less beautiful images of nature) led participants to be more generous and trusting. In Study 4, exposure to more beautiful (versus less beautiful) plants in the laboratory room led participants to exhibit increased helping behavior. Across studies, we provide evidence that positive emotions and tendencies to perceive natural beauty mediate and moderate the association between beauty and prosociality. The current studies extend past research by demonstrating the unique prosocial benefits of beautiful nature.
