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.

<p>This dissertation examines the development of theories about meditative practices and their soteriological goals in Indian Buddhist thought. It traces this development from the earliest stage accessible to us as far as the systematizations of Asanga and Vasubandhu in the fifth century AD. The first two chapters apply the techniques of form-criticism to the first four Nikayas of the Pali canon in an attempt to isolate the types of meditative technique described in this literature. The preliminary attempts at systematization in the Samannaphalasutta and Mahasatipatthanasutta are subjected to detailed analysis. It is found that a wide variety of techniques are recommended in this literature, that these techniques cannot easily be combined into a coherent system of soteriological practice, and that the attempts to so combine them in the Nikayas are frequently inconsistent with each other. The third chapter analyzes in detail Vasubandhu's contribution to this issue as seen in the path-structure set forth in the Abhidharmakosabhasya. Substantial sections of that work are translated, together with the commentaries of Yasomitra and Sthiramati. The fourth chapter analyzes the margasatya section of Asanga's Abhidharmasamuccaya, and gives a complete edition and translation of this section of the work, together with its bhasya, based on the surviving Sanskrit fragments and the Tibetan translation. It is found that the attempts of Asanga and Vasubandhu to resolve the tensions uncovered in the first two chapters are neither fully successful nor compatible with one another. The fifth chapter relates the findings of the first four chapters to current psychological research on the effects of meditative techniques, and discusses in outline the epistemological implications of these findings. It is found that the tensions apparent in the Buddhist texts are reflected in large part by the empirical findings of psychological studies, and that the epistemological implications of these findings have not been properly understood, either by Buddhist philosophers or contemporary psychological theorists.</p>

A former abbot of one of the largest Tibetan Buddhist monasteries in the world, Khensur Jampa Tegchok has been teaching Westerners about Buddhism since the 1970s. With a deep respect for the intellectual capacity of his Western students, Khensur Tegchok here unpacks with great erudition Buddhism’s animating philosophical principle—the emptiness of all appearances. Instead of commenting on a text or relying on a traditional framework, Insight into Emptiness uses accessible language specifically tailored to the Western mind. Engagingly edited by bestselling author Thubten Chodron, emptiness is here approached from a host of angles far beyond most treatments of the subject, while never sacrificing its conversational approach.

<p>The union of samatha (tranquility meditation) and vipasyana (insight meditation) is the unique Buddhist path to deliverance. This dissertation explores various schemes of samatha developed in distinct meditation systems, so as to analyze the different degrees of sam adhi which affect the power of insight in eradication of defilements. The nature of dhyana/jhana is explained quite different in the canonical and commentarial materials of Buddhist schools. How a meditator practices mindfulness of breathing is based on how a meditator interprets what the dhyana/jh ana is. This dissertation provides various possible explanations for the diverse dispositions of meditators in meditation practice. In insight meditation, when consciousness acts with skillful mental qualities, one is able to penetrate the true nature of all physical and mental phenomena; in the cycle of rebirth, consciousness links the present existence and the next. The different roles of consciousness in rebirth, and deliverance are investigated. This dissertation is mainly based on the Chinese Canon to examine key issues in meditation practice, revolving around the significance of tranquility meditation and insight meditation.</p>

<p>This thesis is composed of two parts, one a translation, the other a commentary on the material that has been translated--a set of three well known identically entitled works by the famous Indian Buddhist scholar, Kamalasila (c. 740-795 C.E.). The Bhavanakramas are here translated from both Sanskrit and Tibetan sources. The commentary takes the form of an extended critical Prologue to the texts and is centred around an examination of the notions of meditation and insight as found therein. The first chapter of the commentary examines the various terms for meditation found in the texts and argues for a specific way of translating them that regards as normative only one of these, that is, bhavana . The argument is made that if one is to take the basic Buddhist distinction between intellectual and experiential wisdom seriously, no other concept of meditation will prove satisfactory. The concept of bhavana is contrasted with that of dhyana , and explained in light of other important terms, notably samadhi, samatha and vipasyana . Two different conceptions of samadhi are identified as existing within the texts, one corresponding with dhyana and one with bhavana . The latter is identified as predominant. This conception holds that meditation is not to be principally identified as non-conceptual in nature, but rather encompasses both nonconceptual states and conceptual processes. These latter, however, are not to be identified with ordinary reasoning processes ( cintamayi prajña ) but rather with a form of experiential knowing (bhavanamayi prajña, vipasyana ) that is conceptual in nature. It is in accordance with this conception that the actual translation of the texts has been undertaken.</p>

This project provides for creation of a course that looks at Vipassana meditation from three broad perspectives: experiential, psychological/scientific, and philosophical. Students learn to meditate and compare that experience with other contemplative exercises. They bring that experience to bear on questions about research on well-being and on perennial philosophical questions about the nature of the self.
