We used fMRI to examine amygdala activation in response to fearful facial expressions, measured over multiple scanning sessions. 15 human subjects underwent three scanning sessions, at 0, 2 and 8 weeks. During each session, functional brain images centered about the amygdala were acquired continuously while participants were shown alternating blocks of fearful, neutral and happy facial expressions. Intraclass correlation coefficients calculated across the sessions indicated stability of response in left amygdala to fearful faces (as a change from baseline), but considerably less left amygdala stability in responses to neutral expressions and for fear versus neutral contrasts. The results demonstrate that the measurement of fMRI BOLD responses in amygdala to fearful facial expressions might be usefully employed as an index of amygdala reactivity over extended periods. While signal change to fearful facial expressions appears robust, the experimental design employed here has yielded variable responsivity within baseline or comparison conditions. Future studies might manipulate the experimental design to either amplify or attenuate this variability, according to the goals of the research.

This paper argues the case for meditation with children. It seeks to define what meditation is, why it is important and how it can be practised with children. Meditation provides a good starting point for learning and creativity. It builds upon a long tradition of meditative practice in religious and humanistic settings and research gives evidence of its practical benefits. We need to help children find natural ways for body and mind to combat the pressures of modern living and to find better ways to help focus their minds on matters of importance. There are strong pedagogical reasons for including meditation as part of the daily experience of pupils of all ages and abilities. Meditation is a proven means for stilling the mind, encouraging mindfulness, and providing optimum conditions for generative thinking and reflection. This paper aims to encourage more experimentation and research into meditative practice with children.

This project explores the integration of Zen Buddhist contemplative practices with practices entailed in academic, especially literary, reading. The mindfulness cultivated through Zen practices, and the ethical awareness that can spring from that mindfulness can inspire an academic reading practice that is both faithful to the particulars of a text’s form and sensitive to its ethical and political implications.

<p>Studied the different effects of yoga and psychomotor activity on a coding task, with 34 children referred to a learning center as Ss. They received a baseline period, a control period involving a fine motor task, an experimental treatment, another control period, a treatment reversal, and a control period. The results indicate that order of treatment had no effect on the results. Furthermore, coding scores in the 2nd half of the experiment were higher than those in the 1st half. There was no difference in the effect on performance of yoga and gross motor activities. Irrespective of which treatment was given, scores after treatment were significantly higher than those during the control periods. There are implications for physical education programming in elementary schools.</p>

BACKGROUND: Hypothalamic-pituitary-adrenal (HPA) system activation is adaptive in response to stress, and HPA dysregulation occurs in stress-related psychopathology. It is important to understand the mechanisms that modulate HPA output, yet few studies have addressed the neural circuitry associated with HPA regulation in primates and humans. Using high-resolution F-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in rhesus monkeys, we assessed the relation between individual differences in brain activity and HPA function across multiple contexts that varied in stressfulness.
METHODS: Using a logical AND conjunctions analysis, we assessed cortisol and brain metabolic activity with FDG-PET in 35 adolescent rhesus monkeys exposed to two threat and two home-cage conditions. To test the robustness of our findings, we used similar methods in an archival data set. In this data set, brain metabolic activity and cortisol were assessed in 17 adolescent male rhesus monkeys that were exposed to three stress-related contexts.
RESULTS: Results from the two studies revealed that subgenual prefrontal cortex (PFC) metabolism (Brodmann's area 25/24) consistently predicted individual differences in plasma cortisol concentrations regardless of the context in which brain activity and cortisol were assessed.
CONCLUSIONS: These findings suggest that activation in subgenual PFC may be related to HPA output across a variety of contexts (including familiar settings and novel or threatening situations). Individuals prone to elevated subgenual PFC activity across multiple contexts may be individuals who consistently show heightened cortisol and may be at risk for stress-related HPA dysregulation.

"The practice of contemplation is one of the great spiritual arts," writes Martin Laird in A Sunlit Absence. "Not a technique but a skill, it harnesses the winds of grace that lead us out into the liberating sea of silence." In this companion volume to his bestselling Into the Silent Land, Laird focuses on a quality often overlooked by books on Christian meditation: a vast and flowing spaciousness that embraces both silence and sound, and transcends all subject/object dualisms. Drawing on the wisdom of great contemplatives from St. Augustine and St. Teresa of Avila to St. Hesychios, Simone Weil, and many others, Laird shows how we can uncover the deeper levels of awareness that rest within us like buried treasure waiting to be found. The key insight of the book is that as our practice matures, so will our experience of life's ordeals, sorrows, and joys expand into generous, receptive maturity. We learn to see whatever difficulties we experience in meditation--boredom, lethargy, arrogance, depression, grief, anxiety--not as obstacles to be overcome but as opportunities to practice surrender to what is. With clarity and grace Laird shows how we can move away from identifying with our turbulent, ever-changing thoughts and emotions to the cultivation of a "sunlit absence"--the luminous awareness in which God's presence can most profoundly be felt. Addressed to both beginners and intermediates on the pathless path of still prayer, A Sunlit Absence offers wise guidance on the specifics of contemplative practice as well as an inspiring vision of the purpose of such practice and the central role it can play in our spiritual lives.

Purpose: To systematically review articles reporting on depression, anxiety, and burnout among U.S. and Canadian medical students.
Method: Medline and PubMed were searched to identify peer-reviewed English-language studies published between January 1980 and May 2005 reporting on depression, anxiety, and burnout among U.S. and Canadian medical students. Searches used combinations of the Medical Subject Heading terms medical student and depression, depressive disorder major, depressive disorder, professional burnout, mental health, depersonalization, distress, anxiety, or emotional exhaustion. Reference lists of retrieved articles were inspected to identify relevant additional articles. Demographic information, instruments used, prevalence data on student distress, and statistically significant associations were abstracted.
Results: The search identified 40 articles on medical student psychological distress (i.e., depression, anxiety, burnout, and related mental health problems) that met the authors' criteria. No studies of burnout among medical students were identified. The studies suggest a high prevalence of depression and anxiety among medical students, with levels of overall psychological distress consistently higher than in the general population and age-matched peers by the later years of training. Overall, the studies suggest psychological distress may be higher among female students. Limited data were available regarding the causes of student distress and its impact on academic performance, dropout rates, and professional development.
Conclusions: Medical school is a time of significant psychological distress for physicians-in-training. Currently available information is insufficient to draw firm conclusions on the causes and consequences of student distress. Large, prospective, multicenter studies are needed to identify personal and training-related features that influence depression, anxiety, and burnout among students and explore relationships between distress and competency.

The specific aim of this course is development of a university dance curriculum that will link post-modern dance with Tai Chi as it is understood and practiced by the masters of the discipline in China – both as a practice (i.e., as a set of physical movements known as “Tai Chi Chuan”) and as a spiritual discipline (i.e., “Tai Chi”) worthy of scholarly study. A central hypothesis of this course is that the teaching of Tai Chi Chuan in this country – both in academic and experiential contexts – has generally missed the essence of the actual Chinese discipline by concentrating more on the specific physical steps than on the deeper mental and spiritual principles from which it derives. A major goal of the course is to restore to the curriculum those important principles of employing certain meditation techniques that have not been taught here. The course will apply two central principles of Tai Chi in the context of dance: first, the goal of awareness, or softness, which is simply movement based on stillness; and second, the goal of relational physics, or the intention and orientation of the individual to the whole.

<p>There are a great many books now available describing the complex rituals and esoteric significance of the ancient practices of Buddhist tantra. But none take the friendly, helpful approach of Geshe Tashi Tsering’s Foundation of Buddhist Thought series. Understanding the many questions Westerners have upon first encountering tantra’s colorful imagery and veiled language, Geshe Tsering gives straight talk about deities, initiations, mandalas, and the various stages of tantric development. He even goes through a simple tantric compassion practice written by the Dalai Lama, using it to unpack the building blocks common to all such visualization techniques. Tantra is a fitting conclusion to the folksy and practical wisdom in the Foundation of Buddhist Thought series.</p>

<p>The purpose of this article is to show how meditation can be used to help a student to become an ethical person. Discursive and non-discursive meditation give the student an awareness of ethical issues and lead to the discovery and application of models of ethical conduct. In part one, the student is led through non-discursive meditation to discover him/her self as an ethical person. The student is also given the tools to explore ethical issues. Part two discusses a transition stage from non-discursive to discursive meditation. The student is led to use non-discursive meditation to construct an ethical value system and apply it to his/her own life. An art medium is especially helpful at this stage. Discursive meditation gives the chance for the student to compare who he/she is with what he/she should be. Part three discusses four elements in the construction of an ethical vision with discursive meditaton: First, a picture of reality; second, models of ethical rules; third, models of ethical conduct; fourth, current personal and social values. The conclusion contains a description of the ethical person.</p>

<p>Few counseling programs directly address the importance of self-care in reducing stress and burnout in their curricula. A course entitled Mind/Body Medicine and the Art of Self-Care was created to address personal and professional growth opportunities through self-care and mindfulness practices (meditation, yoga, qigong, and conscious relaxation exercises). Three methods of evaluating this 15-week 3-credit mindfulness-based stress reduction (MBSR) course for counseling students indicated positive changes for students in learning how to manage stress and improve counseling practice. Students reported positive physical, emotional, mental, spiritual, and interpersonal changes and substantial effects on their counseling skills and therapeutic relationships. Information from a focus group, qualitative reports, and quantitative course evaluations were triangulated; all data signified positive student responses to the course, method of teaching, and course instructor. Most students reported intentions of integrating mindfulness practices into their future profession.</p>

<p>Preparation for the role of therapist can occur on both professional and personal levels. Research has found that therapists are at risk for occupationally related psychological problems. It follows that self-care may be a useful complement to the professional training of future therapists. The present study examined the effects of one approach to self-care, Mindfulness-Based Stress Reduction (MBSR), for therapists in training. Using a prospective, cohort-controlled design, the study found participants in the MBSR program reported significant declines in stress, negative affect, rumination, state and trait anxiety, and significant increases in positive affect and self-compassion. Further, MBSR participation was associated with increases in mindfulness, and this enhancement was related to several of the beneficial effects of MBSR participation. Discussion highlights the potential for future research addressing the mental health needs of therapists and therapist trainees.</p>

We investigated the top-down influence of working memory (WM) maintenance on feedforward perceptual processing within occipito-temporal face processing structures. During event-related potential (ERP) recordings, subjects performed a delayed-recognition task requiring WM maintenance of faces or houses. The face-sensitive N170 component elicited by delay-spanning task-irrelevant grayscale noise probes was examined. If early feedforward perceptual activity is biased by maintenance requirements, the N170 ERP component elicited by probes should have a greater N170 amplitude response during face relative to house WM trials. Consistent with this prediction, N170 elicited by probes presented at the beginning, middle, and end of the delay interval was greater in amplitude during face relative to house WM. Thus, these results suggest that WM maintenance demands may modulate early feedforward perceptual processing for the entirety of the delay duration. We argue based on these results that temporally early biasing of domain-specific perceptual processing may be a critical mechanism by which WM maintenance is achieved.

We present a new tensor-based morphometric framework that quantifies cortical shape variations using a local area element. The local area element is computed from the Riemannian metric tensors, which are obtained from the smooth functional parametrization of a cortical mesh. For the smooth parametrization, we have developed a novel weighted spherical harmonic (SPHARM) representation, which generalizes the traditional SPHARM as a special case. For a specific choice of weights, the weighted-SPHARM is shown to be the least squares approximation to the solution of an isotropic heat diffusion on a unit sphere. The main aims of this paper are to present the weighted-SPHARM and to show how it can be used in the tensor-based morphometry. As an illustration, the methodology has been applied in the problem of detecting abnormal cortical regions in the group of high functioning autistic subjects.

BACKGROUND: EEG alpha power has been demonstrated to be inversely related to mental activity and has subsequently been used as an indirect measure of brain activation. The hypothesis that the thalamus serves as a neuronal oscillator of alpha rhythms has been supported by studies in animals, but only minimally by studies in humans.
METHODS: In the current study, PET-derived measures of regional glucose metabolism, EEG, and structural MRI were obtained from each participant to assess the relation between thalamic metabolic activity and alpha power in depressed patients and healthy controls. The thalamus was identified and drawn on each subject's MRI. The MRI was then co-registered to the corresponding PET scan and metabolic activity from the thalamus extracted. Thalamic activity was then correlated with a 30-min aggregated average of alpha EEG power.
RESULTS: Robust inverse correlations were observed in the control data, indicating that greater thalamic metabolism is correlated with decreased alpha power. No relation was found in the depressed patient data.
CONCLUSIONS: The results are discussed in the context of a possible abnormality in thalamocortical circuitry associated with depression.

The information processing capacity of the human mind is limited, as is evidenced by the attentional blink-a deficit in identifying the second of two targets (T1 and T2) presented in close succession. This deficit is thought to result from an overinvestment of limited resources in T1 processing. We previously reported that intensive mental training in a style of meditation aimed at reducing elaborate object processing, reduced brain resource allocation to T1, and improved T2 accuracy [Slagter, H. A., Lutz, A., Greischar, L. L., Francis, A. D., Nieuwenhuis, S., Davis, J., et al. Mental training affects distribution of limited brain resources. PloS Biology, 5, e138, 2007]. Here we report EEG spectral analyses to examine the possibility that this reduction in elaborate T1 processing rendered the system more available to process new target information, as indexed by T2-locked phase variability. Intensive mental training was associated with decreased cross-trial variability in the phase of oscillatory theta activity after successfully detected T2s, in particular, for those individuals who showed the greatest reduction in brain resource allocation to T1. These data implicate theta phase locking in conscious target perception, and suggest that after mental training the cognitive system is more rapidly available to process new target information. Mental training was not associated with changes in the amplitude of T2-induced responses or oscillatory activity before task onset. In combination, these findings illustrate the usefulness of systematic mental training in the study of the human mind by revealing the neural mechanisms that enable the brain to successfully represent target information.
