Pain can be modulated by several cognitive techniques, typically involving increased cognitive control and decreased sensory processing. Recently, it has been demonstrated that pain can also be attenuated by mindfulness. Here, we investigate the underlying brain mechanisms by which the state of mindfulness reduces pain. Mindfulness practitioners and controls received unpleasant electric stimuli in the functional magnetic resonance imaging scanner during a mindfulness and a control condition. Mindfulness practitioners, but not controls, were able to reduce pain unpleasantness by 22% and anticipatory anxiety by 29% during a mindful state. In the brain, this reduction was associated with decreased activation in the lateral prefrontal cortex and increased activation in the right posterior insula during stimulation and increased rostral anterior cingulate cortex activation during the anticipation of pain. These findings reveal a unique mechanism of pain modulation, comprising increased sensory processing and decreased cognitive control, and are in sharp contrast to established pain modulation mechanisms.

Sometimes life seems like it's all about hurrying--so many places to go! And sometimes it's hard when things don't go your way--it can make a piggy angry and sad. So how do young piggies find a peaceful place in a frustrating world? They meditate!

<p>The premise of this dissertation is that Buddhism must inculturate to meet the context of contemporary North America. Given the widespread interest in the application of Buddhist-derived ideas and practices in a host of secular settings, the capacity for teachers to engage with new ideas and disciplines will be crucial to the tradition's continued relevance. Because there is a high demand for and interest in Buddhist-derived programming in secular spaces, the number of individuals and organizations striving to meet this demand is mushrooming. This trend, coupled with a dearth of professional training programs and accreditation processes means that not only are there an eclectic array of approaches being used to teach meditation, but there is also minimal discourse engaging the crucial question of what constitutes effective pedagogy or adequate training processes for teachers. Chapter 1 establishes the need for the inculturation of Buddhism. This imperative for adaptation raises fundamental questions regarding how to best evaluate the authenticity of changes to traditional teaching methods. In Chapters 2 and 3, the Buddhist doctrine of skillful means is explored with an eye toward distilling guiding principles for analyzing this process of adaptation of teachings to meet a variety of cultural and personal perspectives. Drawing from Mahayana and pre-Mahayana sutras, traditions of commentary, and contemporary hermeneutics, a set of priorities based on the perspective of the Buddhist tradition is proposed. In Chapter 4, it is established that finding points of relevance to particular cultural concerns such as physical and mental health issues has been a vital component of existing efforts toward secularized meditation programs to date. This chapter concludes by drawing out of such present practices additional guiding principles to advance the process of pedagogical inculturation. Despite the widespread interest in applying meditation to a variety of settings, the pedagogy and philosophy of education behind the various approaches remains largely under-theorized. To fill this need, Chapter 5 establishes a set of guiding principles for pedagogical adaptation, drawing from the tradition's own self-understanding as well as from the insights of Western education as discussed in the prior 4 chapters. Finally, Chapter 6 offers an example of inculturated pedagogy at work.</p>

Several authors have argued that because mindfulness training involves repeated practice of the self-regulation of attention, it should lead to measurable improvements in attentional skills and related memory processes. Although a few studies have shown relationships between mindfulness training and performance-based tests of attention and memory, findings are mixed. In the present study, a sample of 33 adults with a long-term mindfulness meditation practice (average duration of 6 years) was compared with a demographically matched sample of nonmeditators on several widely used tests of attention and memory functioning, including sustained attention, attention switching, inhibition of elaborative processing, working memory, and short- and long-term memory. Group differences were nonsignificant for all of the attentional tasks. The only significant group differences were in short-term memory (both free and cued recall) and long-term memory (free recall only). Results suggest that the nature of the attentional and memory processing that is cultivated by mindfulness training requires clarification.

<p>The scientific study of Buddhist meditation has proceeded without much attention to Buddhist literature that details the range of psychological and physiological changes thought to occur during meditation. This paper presents reports of various meditation-induced light experiences derived from American Buddhist practitioners. The reports of light experiences are classified into two main types: discrete lightforms and patterned or diffuse lights. Similar phenomena are well documented in traditional Buddhist texts but are virtually undocumented in scientific literature on meditation. Within Buddhist traditions, these phenomena are attributed a range of interpretations. However, because it is insufficient and problematic to rely solely upon the textual sources as a means of investigating the cause or significance of these phenomena, these qualitative reports are also considered in relation to scientific research on light-related experiences in the context of sensory deprivation, perceptual isolation, and clinical disorders of the visual system. The typologies derived from these studies also rely upon reports of experiences and closely match typologies derived from the qualitative study of contemporary practitioners and typologies found in Buddhist literary traditions. Taken together, these studies also provide evidence in support of the hypothesis that certain meditative practices – especially those that deliberately decrease social, kinesthetic, and sensory stimulation and emphasize focused attention – have perceptual and cognitive outcomes similar to sensory deprivation. Given that sensory deprivation increases neuroplasticity, meditation may also have an enhanced neuroplastic potential beyond ordinary experience-dependent changes. By providing and contextualizing these reports of meditation-induced light experiences, scientists, clinicians, and meditators gain a more informed view of the range of experiences that can be elicited by contemplative practices.</p>

Objective To investigate the effect of mindfulness training on pain tolerance, psychological well-being, physiological activity, and the acquisition of mindfulness skills. Methods Forty-two asymptomatic University students participated in a randomized, single-blind, active control pilot study. Participants in the experimental condition were offered six (1-h) mindfulness sessions; control participants were offered two (1-h) Guided Visual Imagery sessions. Both groups were provided with practice CDs and encouraged to practice daily. Pre–post pain tolerance (cold pressor test), mood, blood pressure, pulse, and mindfulness skills were obtained. Results Pain tolerance significantly increased in the mindfulness condition only. There was a strong trend indicating that mindfulness skills increased in the mindfulness condition, but this was not related to improved pain tolerance. Diastolic blood pressure significantly decreased in both conditions. Conclusion Mindfulness training did increase pain tolerance, but this was not related to the acquisition of mindfulness skills.

Objectives: To examine whether mindfulness meditation (MM) was associated with changes in objectively measured polysomnographic (PSG) sleep profiles and to relate changes in PSG sleep to subjectively reported changes in sleep and depression within the context of a randomized controlled trial. Previous studies have indicated that mindfulness and other forms of meditation training are associated with improvements in sleep quality. However, none of these studies used objective PSG sleep recordings within longitudinal randomized controlled trials of naïve subjects. Methods: Twenty-six individuals with partially remitted depression were randomized into an 8-week Mindfulness-Based Cognitive Therapy (MBCT) course or a waitlist control condition. Pre-post measurements included PSG sleep studies and subjectively reported sleep and depression symptoms. Results: According to PSG sleep, MM practice was associated with several indices of increased cortical arousal, including more awakenings and stage 1 sleep and less slow-wave sleep relative to controls, in proportion to amount of MM practice. According to sleep diaries, subjectively reported sleep improved post MBCT but not above and beyond controls. Beck Depression Inventory scores decreased more in the MBCT group than controls. Improvements in depression were associated with increased subjective sleep continuity and increased PSG arousal. Conclusions: MM is associated with increases in objectively measured arousal during sleep with simultaneous improvements in subjectively reported sleep quality and mood disturbance. This pattern is similar to the profiles of positive responders to common antidepressant medications.

This report is a summary of the Contemplative Net Project’s findings. The report begins by reviewing the historical and cultural context for the current interest in meditation and other contemplative practices. The secular application of these practices is then surveyed in five professional fields: Business and Organizational Development, Medicine and Healthcare, Education and Youth Work, Law and Government, and Prison Work. Through the use of stories, profiles, and quotes from research interviews, the report offers an indepth, narrative look at how exposure to meditation and other practices has impacted individuals, workplaces, and society at large.

The ‘problem of other minds’ is central to sociological theory and of immediate importance to contemporary research on subjectivity and interiority. How do we cultivate and maintain an intersubjective space during silent, private, experiences? Drawing on Alfred Schutz’s phenomenology, this study challenges the common view which regards silence as an obstacle to social relations. The data consist of two years of participant observation of vipassana meditation practices in Israel and the United States. Vipassana meditation is conducted in complete silence, discouraging group sharing of meditation experiences, thus offering an extreme case of silence and privacy. The findings illustrate how, despite the absence of direct verbal communication, the practice of meditation still holds important intersubjective dimensions. I suggest that covert mechanisms of silent intersubjectivity play an important role in everyday social life and require further ethnographic attention.

The Indo-Tibetan tradition claims that proficiency in the suggested longevity practices of meditation, diet, and physical exercise (yoga), will result in profound anti-aging, stress-mediating and health enhancing effects. Western biomedical research has begun to demonstrate that the psychobiological states induced and cultivated by cognitive behavioral practices which are emblematic of those contained within the Indo-Tibetan tradition (hypnosis, meditation, visualization, systematic relaxation), indeed do have a profound impact on the body's protective and regulatory systems. Although continued study is necessary, much of the early research illuminating the mechanisms responsible for the life-span extending and health-enhancing effects of these cognitive behavioral practices points to the importance of their anti-inflammatory, anti-stress, and antioxidant effects as well as their impact in enhancing the production of endogenous substances that possess general longevity-enhancing, regenerative properties.

<p>Objective: To provide a comprehensive review and evaluation of the psychological and neurophysiological literature pertaining to mindfulness meditation.Methods: A search for papers in English was undertaken using PsycINFO (from 1804 onward), MedLine (from 1966 onward) and the Cochrane Library with the following search terms: Vipassana, Mindfulness, Meditation, Zen, Insight, EEG, ERP, fMRI, neuroimaging and intervention. In addition, retrieved papers and reports known to the authors were also reviewed for additional relevant literature.Results: Mindfulness-based therapeutic interventions appear to be effective in the treatment of depression, anxiety, psychosis, borderline personality disorder and suicidal/self-harm behaviour. Mindfulness meditation per se is effective in reducing substance use and recidivism rates in incarcerated populations but has not been specifically investigated in populations with psychiatric disorders. Electroencephalography research suggests increased alpha, theta and beta activity in frontal and posterior regions, some gamma band effects, with theta activity strongly related to level of experience of meditation; however, these findings have not been consistent. The few neuroimaging studies that have been conducted suggest volumetric and functional change in key brain regions.Conclusions: Preliminary findings from treatment outcome studies provide support for the application of mindfulness-based interventions in the treatment of affective, anxiety and personality disorders. However, direct evidence for the effectiveness of mindfulness meditation per se in the treatment of psychiatric disorders is needed. Current neurophysiological and imaging research findings have identified neural changes in association with meditation and provide a potentially promising avenue for future research.</p>

<p>Although mindfulness meditation traditionally is viewed as a lifelong practice, much current knowledge about its effects is based on short-term practitioners who have participated in mindfulness-based treatment. In the current study, long-term meditators and demographically similar nonmeditators completed self-report measures of constructs expected to be related to the practice of mindfulness meditation. Extent of meditation experience was correlated in the expected directions with levels of mindfulness and with many other variables. Mean differences between meditators and nonmeditators were significant in most cases. Mediation analyses were consistent with the hypothesis that practicing meditation is associated with increased mindfulness in daily life, which is related to decreased rumination, decreased fear of emotion, and increased behavioral self-regulation. These mechanisms appear partially responsible for the relationships between mindfulness skills and psychological adjustment. Overall, the current study suggests that the long-term practice of mindfulness meditation may cultivate mindfulness skills and promote adaptive functioning.</p>
