An attempt towards differentiating attentional deficits in traumatic brain injury

Attentional deficits in patients suffering traumatic brain injury (TBI) can occur with minor to severe impact to the brain. Based on reviews of both the cognitive and neurobehavioral literature, the following three concepts of attention are addressed: (a) arousal/alertness, (b) selective attention, and (c) energetic aspects of attention, which include such components as effort, resource allocation, and speed of processing. Within each concept, definitions are proposed, the underlying brain mechanisms are identified, and the specific deficits associated with TBI are explored. This review combines theoretical perspectives and clinical findings with the objective of leading toward a diagnostic differentiation that in turn will benefit treatment planning.     

ZYGON'S 1996 EXPEDITION INTO NEUROSCIENCE AND RELIGION

Abstract. Neuroscience is in a period of explosive growth. To address the implications of the new findings for religion and science, Zyvon in 1996 published fifteen articles in this field. Although the authors'explorations of neuroscience and religion are various, three issues in particular are addressed repeatedly: (1) the nature of human identity, or hallmarks of humanness; (2) the nature and origin of religious consciousness; and (3) our means of discovering or constructing order and integration in the brain/mind, in the environment, and holistically. With these categories as templates, this article correlates the findings of the Zygon neuroscience contributors of 1996.     

CRISIS OF BRAIN AND SELF

Abstract. Neuroscientific evidence requires a monistic understanding of brain/mind. Truly appropriating what this means confronts us with the vulnerability of the human condition. Ca-muss absurd and Tillich's despair are extreme expressions of a similar confrontation. This crisis demands a type of courage that is consistent with scientific truth and does not undermine the spiritual dimension of life. That dimension is not a separate substance but the process by which brain/mind meaningfully wrestles with its crisis through aesthetic symbols, religious faith, and ethical affirmation. The validity of these activities does not depend upon human autonomy but instead upon the fact that they exist. Furthermore, they constitute the self, which Dennett calls a "center of narrative gravity."     

HOMO RELIGIOSUS AND ITS BRAIN: REALITY, IMAGINATION, AND THE FUTURE OF NATURE

Abstract. “Daddy, is God real or is he a part of people's imagination?” The brain constructs reality by bottom-up, genetically programmed mechanisms. Nature selected the human holistic, symbolically thinking, aesthetic brain using a mechanism of brain-language coevolution. Our religious nature and moral capabilities are rooted in this brain, and in the real images it constructs.     

Traumatic brain injury: Implications for practice

This article presents a brief overview of the prevalence and history of traumatic brain injury (TBI), discusses the multidimensional effects of TBI, describes the current focus of TBI rehabilitation, and summarizes outcomes from (re)habilitation work with individuals with traumatic brain injury. The importance of this critical area to rehabilitation personnel is discussed, along with suggestions for future research and evaluation studies.     

Can Science Help Construct a New Global Ethic? The Development and Implications of Moral Transformation Theory

This paper reports the results of a ten-year search for consensus among scientific findings on the nature of the origin and development of moral sensitivity and morality. Significant agreement on six underlying factors was found. Based on these foundations, a new theory of moral transformation and a scientific "global ethic" relating to the global ethic of Hans Kung and the Parliament of the World's Religions is proposed. Fields surveyed include psychology, sociology, political science, economics, history, and gender and feminist studies in social science; physics and biology in natural science; and brain research, archaeology, and both old and new evolutionary studies and theory, including chaos, self-organizing, and other nonlinear theories, in systems science.     

Global Progress II: Evolutionary Mechanisms and their Side-effects

This paper attempts to update the 18th century concept of progress by an evolutionary theoretical framework, while replying to some of the contemporary critiques. Progress, understood as increase in fitness (or its proxy, quality of life) necessarily accompanies evolution by natural selection. In socio-cultural evolution, this mechanism is reinforced by growth of knowledge and virtuous cycles, but can be accompanied by negative side-effects such as overshooting and parasitism. The most pressing of the contemporary side-effects, such as pollution and the increased pace of life, are discussed, but it is concluded that they can be tackled without really endangering global progress. The anxiety that they engender is unfortunately amplified by a bad news bias in the media, leading to an inappropriately pessimistic view of the situation by the public.     

The relations between neuroscience and human behavioral science.

Neuroscience seeks to understand how the human brain, perhaps the most complex electrochemical machine in the universe, works, in terms of molecules, membranes, cells and cell assemblies, development, plasticity, learning, memory, cognition, and behavior. The human behavioral sciences, in particular psychiatry and clinical psychology, deal with disorders of human behavior and mentation. The gap between neuroscience and the human behavioral sciences is still large. However, some major advances in neuroscience over the last two decades have diminished the span. This article reviews the major advances of neuroscience in six areas with relevance to the behavioral sciences: (a) evolution of the nervous system; (b) visualizing activity in the human brain; (c) plasticity of the cerebral cortex; (d) receptors, ion channels, and second/third messengers; (e) molecular genetic approaches; and (f) understanding integrative systems with networks and circadian clocks as examples.     

THE RELIGION OF A SCIENTIST: EXPLORATIONS INTO REALITY (RELIGIO PHILOSOPHI NATURALIS)

Abstract. Sir Thomas Browne's reflection on the synthesis between his Christian religion and his practice as a medical doctor, made over three centuries ago, leads into reflections on the present relation between religion and science in the personal experience of the writer. An account is given of how the actual practice of scientific investigation led the author to theistic inferences and how the study of DNA provoked questions concerning reductionism and emergence. This evoked the need for a map of knowledge, and an attempt is presented in a figure which also serves to clarify what kind of realistic reference is involved in both scientific and humanistic contexts–especially with respect to personal language. Theological investigations thereby receive at least provisional legitimization and, with this encouragement, the article pursues the questions of the nature of the divine Source ("God") of the world's being and becoming, of God's interaction and communication with the world, especially with human beings in that world. The penultimate section outlines why the writer considers an explicit communication from God to humanity in Jesus of Nazareth is coherent with the foregoing and what this implies for human fulfillment, individually and corporately. The article concludes with a plea for humility before God and nature in our inquiries in the spirit both of Sir Thomas Browne and of the arch "agnostic" T. H. Huxley.     

Emotional behavior as an agenda in neuropsychological evaluation

In an effort to objectify neuropsychologic evaluations, consideration of a patient's emotional behavior has often been neglected. An extensive literature review is undertaken in an effort to document lateralized emotional behaviors commonly found in brain injury populations. This evidence is contrasted with the psychiatric symptoms and lateralized neuropsychologic impairments seen in major depression and schizophrenia. A theoretical model is then proposed that attempts to integrate these functional vs. organic symptoms based upon reciprocal inhibition of lateralized emotional functioning in brain injury and psychiatric disorders. This opponent process model not only seems to account for some of the discrepant findings in the literature, but additionally provides a cogent and useful marker to neurophychologically differentiate neuronal vs. metabolic disorders. The model further suggests new ways of envisioning treatment and recovery from both psychiatric illness and brain injury.
