A key early fifteenth-century Tibetan historical work that includes all the main schools of Tibetan Buddhism as they existed up to the fifteenth-century, but mainly focused on the Kagyü (bka' brgyud) schools. (BJN)

BACKGROUND: The frontal lobe has been crucially involved in the neurobiology of major depression, but inconsistencies among studies exist, in part due to a failure of considering modulatory variables such as symptom severity, comorbidity with anxiety, and distinct subtypes, as codeterminants for patterns of brain activation in depression. METHODS: Resting electroencephalogram was recorded in 38 unmedicated subjects with major depressive disorder and 18 normal comparison subjects, and analyzed with a tomographic source localization method that computes the cortical three-dimensional distribution of current density for standard electroencephalogram frequency bands. Symptom severity and anxiety were measured via self-report and melancholic features via clinical interview. RESULTS: Depressed subjects showed more excitatory (beta3, 21.5-30.0 Hz) activity in the right superior and inferior frontal lobe (Brodmann's area 9/10/11) than comparison subjects. In melancholic subjects, this effect was particularly pronounced for severe depression, and right frontal activity correlated positively with anxiety. Depressed subjects showed posterior cingulate and precuneus hypoactivity. CONCLUSIONS: While confirming prior results implicating right frontal and posterior cingulate regions, this study highlights the importance of depression severity, anxiety, and melancholic features in patterns of brain activity accompanying depression.

Purpose Evaluate impact of breathing awareness meditation (BAM), Botvin LifeSkills® Training (LST), and health education control (HEC) on ambulatory blood pressure (BP) and sodium excretion in African American (AA) adolescents. Methods Following three consecutive days of systolic blood pressure (SBP) screenings, 166 eligible participants (i.e., SBP > 50th – 95th percentile) were randomized by school to either BAM (n = 53), LST (n= 69), or HEC (n=44). In-school intervention sessions were administered for three months by health education teachers. Before and after the intervention overnight urine samples and 24-hour ambulatory SBP, diastolic blood pressure (DBP), and heart rate (HR) were obtained. Results Significant group differences were found for changes in overnight SBP and SBP, DBP and HR over the 24-hour period and during school hours. The BAM treatment exhibited the greatest overall decreases on these measures (Bonferroni adjusted, ps <.05). For example, for school-time SBP, BAM showed a change of −3.7 mmHg compared to no change for LST and a change of −0.1 mmHg for HEC. There was a non-significant trend for overnight urinary sodium excretion (p = .07) with the BAM group displaying a reduction of −.92 ± 1.1 mEq/hr compared to increases of .89 ± 1.2 mEq/hr for LST, and .58±0.9 mEq/hr for HEC group. Conclusion BAM appears to improve hemodynamic function and may impact sodium handling among AA adolescents at increased risk for development of cardiovascular disease (CVD).

Publisher's description: Buddha Mind in Contemporary Art documents the growing presence of Buddhist perspectives in contemporary culture. This shift began in the nineteenth century and is now pervasive in many aspects of everyday experience. In the arts especially, the increasing importance of process over product has promoted a profound change in the relationship between artist and audience. But while artists have been among the most perceptive interpreters of Buddhism in the West, art historians and critics have been slow to develop the intellectual tools to analyze the impact of Buddhist concepts. This timely, multi-faceted volume explores the relationships between Buddhist practice and the contemporary arts in lively essays by writers from a range of disciplines and in revealing interviews with some of the most influential artists of our time. Elucidating the common ground between the creative mind, the perceiving mind, and the meditative mind, the contributors tackle essential questions about the relationship of art and life. Among the writers are curators, art critics, educators, and Buddhist commentators in psychology, literature, and cognitive science. They consider the many Western artists today who recognize the Buddhist notion of emptiness, achieved through focused meditation, as a place of great creative potential for the making and experiencing of art. The artists featured in the interviews, all internationally recognized, include Maya Lin, Bill Viola, and Ann Hamilton. Extending earlier twentieth-century aesthetic interests in blurring the boundaries of art and life, the artists view art as a way of life, a daily practice, in ways parallel to that of the Buddhist practitioner. Their works, woven throughout the book, richly convey how Buddhism has been both a source for and a lens through which we now perceive art.

Professor George has ventured into a comparatively unchartered area seeking, as he does, to explore the art and concept of performance in Buddhism -- more specially in the context of Buddhist meditation and theatre. Spelling out the epistemology of performance in all its different connotations and definitional nuances, his study opens out an astonishingly vast panorama of the Buddhist theatrical practices in Sri Lanka, China, Japan, Nepal, Tibet . . . and goes on to demonstrate how, within this panorama, three kinds of theatrical practice can be identified, each corresponding to one of the three paths open to a Buddhist: the karma path, the Bodhisattva option, and enlightenment, and each representative of one of the three main cultures of Buddhism -- the Hinayana, Mahayana, Vajrayana. Supported by extensive endnotes and bibliographic references, Dr. George's book also carries a range of case studies of the art of performance in Buddhism, with definitive examples, among others, of the Sri Lankan Kandy dance and Karma drama, Tibetan Chams and Chod, and Japanese Noh.

The category "experience" has played a cardinal role in modern studies of Buddhism. Few scholars seem to question the notion that Buddhist monastic practice, particularly meditation, is intended first and foremost to inculcate specific religious or "mystical" experiences in the minds of practitioners. Accordingly, a wide variety of Buddhist technical terms pertaining to the "stages on the path" are subject to a phenomenological hermeneutic-they are interpreted as if they designated discrete "states of consciousness" experienced by historical individuals in the course of their meditative practice. This paper argues that the role of experience in the history of Buddhism has been greatly exaggerated in contemporary scholarship. Both historical and ethnographic evidence suggests that the privileging of experience may well be traced to certain twentieth-century Asian reform movements, notably those that urge a "return" to zazen or vipassanā meditation, and these reforms were profoundly influenced by religious developments in the West. Even in the case of those contemporary Buddhist schools that do unambiguously exalt meditative experience, ethnographic data belies the notion that the rhetoric of meditative states functions ostensively. While some adepts may indeed experience "altered states" in the course of their training, critical analysis shows that such states do not constitute the reference points for the elaborate Buddhist discourse pertaining to the "path." Rather, such discourse turns out to function ideologically and performatively-wielded more often than not in the interests of legitimation and institutional authority.

Background and objectives. Cancer-related cognitive impairment has been acknowledged as a substantial limiting factor in quality of life among cancer patients and survivors. In addition to deficits on behavioral measures, abnormalities in neurologic structure and function have been reported. In this paper, we review findings from the literature on cognitive impairment and cancer, potential interventions, meditation and cognitive function, and meditation and cancer. In addition, we offer our hypotheses on how meditation practice may help to alleviate objective and subjective cognitive function, as well as the advantages of incorporating a meditation program into the treatment of cancer patients and survivors for cancer-related cognitive deficits. Findings. Various factors have been hypothesized to play a role in cancer-related cognitive impairment including chemotherapy, reduced hormone levels, proinflammatory immune response, fatigue, and distress. Pharmacotherapies such as methylphenidate or modafinil have been suggested to alleviate cognitive deficits. While initial reports suggest they are effective, some pharmacotherapies have side effects and may not relieve other symptoms associated with multimodal cancer treatment including sleep disturbance, nausea and pain. Several recent studies investigating the effects of meditation programs have reported behavioral and corresponding neurophysiological modulations that may be particularly effective in alleviating cancer-related cognitive impairment. Such programs also have been shown to reduce stress, fatigue, nausea and pain, and improve mood and sleep quality. Conclusions. With the increasing success of cancer treatment and the ability to return to previous family, social, and work activities, symptom management and quality of life are an essential part of survivorship. We propose that meditation may help to improve cancer-related cognitive dysfunction, alleviate other cancer-related sequelae, and should be fully investigated as an adjuvant to cancer treatment.

This chapter introduces contemplative practices, studies, and pedagogy and argues in support of a contemplative pedagogy.

The aim of this article is threefold: It attempts to 1) identify the characteristics of East Asian forms of meditation, as compared to meditation in other parts of the Eurasian continent; 2) test the usefulness of a definition of meditation as a self-administered technique for inner transformation; and 3) test the usefulness of a classification of meditation techniques based on generic features of the meditation object, in particular location (external vs. internal), agency (spontaneous vs. produced), and faculty (cognitive vs. sensory). While the variation among East Asian forms of meditation is considerable, they (along with Indic forms) are often more technical and less consistently devotional than their Western counterparts, and less often sound-based than their Indic counterparts. In a number of ways, both the definition and classification system suggested turn out to be helpful in the analysis of East Asian forms of meditation.

Some children show emotion that is not consistent with normative appraisal of the context and can therefore be defined as context inappropriate (CI). The authors used individual growth curve modeling and hierarchical multiple regression analyses to examine whether CI anger predicts differences in hypothalamic-pituitary-adrenal axis activity, as manifest in salivary cortisol measures. About 23% of the 360 children (ages 6-10 years, primarily 7-8) showed at least 1 expression of CI anger in situations designed to elicit positive affect. Expression of anger across 2 positive assessments was less common (around 4%). CI anger predicted the hypothesized lower levels of cortisol beyond that attributed to context appropriate anger. Boys' CI anger predicted lower morning cortisol and flatter slopes. Results suggest that this novel approach to studying children's emotion across varying contexts can provide insight into affective style.

Centring and opening meditation processes are included in nursing theories and frequently recommended in health care for stress management. These meditation processes are integrated into emerging psychotherapy approaches and there is a rapidly expanding body of neuroscience research distinguishing brain activity associated with different types of meditation. Currently, there is a lack of theoretical and conceptual clarity needed to guide meditation research in health care. Data sources A search of healthcare literature between 2006-2011 was conducted using Alt HealthWatch, CINAHL, PsychNET and PubMed databases using the keywords 'centring' and 'opening' alone and in combination with the term 'meditation.' For the concept centring, 10 articles and 11 books and for the concept opening 13 articles and 10 books were included as data sources. Method Rodgers' evolutionary method of concept analysis was used. Results Centring and opening are similar in that they both involve awareness in the present moment; both use a gentle, effortless approach; and both have a calming effect. Key differences include centring's focus on the individual's inner experience compared with the non-dual, spacious awareness of opening. Conclusion Centring and opening are overlapping, yet distinct meditation processes. The term meditation cannot be used in a generic way in health care. The differences between centring and opening have important implications for the further development of unitary-transformative nursing theories.

The authors compared 12 pairs of cerebral [18F]-fluoro-deoxyglucose (FDG) 2D/3D image sets from a GE/Advance PET scanner, incorporating the actual corrections used on human subjects. Differences in resolution consistent with other published values were found. There is a significant difference in axial resolution between 2D and 3D, and the authors focused on this as it is a scanner feature that cannot be readily changed. Previously published values for spatial axial resolution in 2D and 3D modes were used to model the differential axial smoothing at each image voxel. This model was applied to the 2D FDG images, and the resulting smoothed data indicate the published differences in axial resolution between 2D and 3D modes can account for 30-40% of the differences between these image sets. The authors then investigated the effect this difference might have on analysis typically performed on human FDG data. A phantom containing spherical hot- and cool-spots in a warm background to mimic a typical human cerebral FDG PET scan was scanned for a variety of time durations (30, 15, 5, 1 min). Only for the 1-minute frame (total counts 2D:6M, 3D:30M) is there an advantage to using 3D mode; for the longer frames which are more typical of a human FDG protocol, the reliability for extracting regions-of-interest is the same for either mode while 2D mode shows better quantitative accuracy

Psychological stress is a major provocative factor of symptoms in chronic inflammatory conditions. In recent years, interest in addressing stress responsivity through meditation training in health-related domains has increased astoundingly, despite a paucity of evidence that reported benefits are specific to meditation practice. We designed the present study to rigorously compare an 8-week Mindfulness-Based Stress Reduction (MBSR) intervention to a well-matched active control intervention, the Health Enhancement Program (HEP) in ability to reduce psychological stress and experimentally-induced inflammation. The Trier Social Stress Test (TSST) was used to induce psychological stress and inflammation was produced using topical application of capsaicin cream to forearm skin. Immune and endocrine measures of inflammation and stress were collected both before and after MBSR training. Results show those randomized to MBSR and HEP training had comparable post-training stress-evoked cortisol responses, as well as equivalent reductions in self-reported psychological distress and physical symptoms. However, MBSR training resulted in a significantly smaller post-stress inflammatory response compared to HEP, despite equivalent levels of stress hormones. These results suggest behavioral interventions designed to reduce emotional reactivity may be of therapeutic benefit in chronic inflammatory conditions. Moreover, mindfulness practice, in particular, may be more efficacious in symptom relief than the well-being promoting activities cultivated in the HEP program.

The ability to accurately infer others’ mental states from facial expressions is important for optimal social functioning and is fundamentally impaired in social cognitive disorders such as autism. While pharmacologic interventions have shown promise for enhancing empathic accuracy, little is known about the effects of behavioral interventions on empathic accuracy and related brain activity. This study employed a randomized, controlled and longitudinal design to investigate the effect of a secularized analytical compassion meditation program, cognitive-based compassion training (CBCT), on empathic accuracy. Twenty-one healthy participants received functional MRI scans while completing an empathic accuracy task, the Reading the Mind in the Eyes Test (RMET), both prior to and after completion of either CBCT or a health discussion control group. Upon completion of the study interventions, participants randomized to CBCT and were significantly more likely than control subjects to have increased scores on the RMET and increased neural activity in the inferior frontal gyrus (IFG) and dorsomedial prefrontal cortex (dmPFC). Moreover, changes in dmPFC and IFG activity from baseline to the post-intervention assessment were associated with changes in empathic accuracy. These findings suggest that CBCT may hold promise as a behavioral intervention for enhancing empathic accuracy and the neurobiology supporting it.
