Definitions of dreaming are not required to map formal features of mental activity onto brain measures. While dreaming occurs during all stages of sleep, intense dreaming is largely confined to REM. Forebrain structures and many neurotransmitters can contribute to sleep and dreaming without negating brainstem and aminergic-cholinergic control mechanisms. Reductionism is essential to science and AIM has considerable heuristic value. Recent findings support sleep's role in learning and memory. Emerging technologies may address long-standing issues in sleep and dream research.

Thinking is known to be state dependent but a systematic study of how thinking in dreams differs from thinking while awake has not been done. The study consisted of analyzing the dream reports of 26 subjects who, in addition to providing dream reports also provided answers to questions about their thinking within the dream. Our hypothesis was that thinking in dreams is not monolithic but has two distinct components, one that is similar to wake-state cognition, and another that is fundamentally different. We found that cognition within a dream scenario was similar to that of wake-state cognition, but that thinking about the scenario itself was deficient and very different than wake-state thinking

Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent neuroimaging and neurophysiological studies also differentiate REM, NREM, and waking in features with phenomenological implications. Both evidence and theory suggest that there are isomorphisms between the phenomenology and the physiology of dreams. We present a three-dimensional model with specific examples from normally and abnormally changing conscious states. Key Words: consciousness; dreaming; neuroimaging; neuromodulation; NREM; phenomenology; qualia; REM; sleep

Consciousness can be studied only if subjective experience is documented and quantified, yet first-person accounts of the effects of brain injury on conscious experience are as rare as they are potentially useful. This report documents the alterations in waking, sleeping, and dreaming caused by a lateral medullary infarct. Total insomnia and the initial suppression of dreaming was followed by the gradual recovery of both functions. A visual hallucinosis during waking that was associated with the initial period of sleep and dream suppression is described in detail. Since the changes in sleep and their recovery are comparable to results of animal experiments, it can be concluded that damage to the medullary brain stem causes extreme but short-lived alterations in conscious state and that substantial recovery occurs even though the damage to the brain stem endures.

The studies reported in the following articles are aimed at providing a comprehensive, detailed, and quantitative picture of cognition in human dreaming. Our main premises are that waking, REM sleep, and non-REM sleep represent physiologically distinct and identifiable brain states and that the differences between waking, REM, and NREM mentation reflect these physiological differences. We have studied dreams at a formal level of analysis and, in these papers, have studied the specific dream properties of emotions, bizarre transformations, scene shifts, and plot coherence, in adults and 4- to 10-year-old children, as part of a larger effort to map state-dependent mental phenomena back onto the varying neurobiological processes that must underlie them. We believe that such efforts will enhance our understanding not only of dreaming and its neurophysiological substrates, but also of the cognitive processes that dreaming shares with other unusual mental states

The nature and time course of sleep onset (hypnagogic) mentation was studied in the home environment using the Nightcap, a reliable, cost-effective, and relatively noninvasive sleep monitor. The Nightcap, linked to a personal computer, reliably identified sleep onset according to changes in perceived sleepiness and the appearance of hypnagogic dream features. Awakenings were performed by the computer after 15 s to 5 min of sleep as defined by eyelid quiescence. Awakenings from longer periods of sleep were associated with (1) an increase in reported sleepiness, (2) a decrease in the length of mentation reports, (3) a decrease in the frequency of reports of normal, wake-like thoughts, (4) an increase in the frequency of ''unusual thoughts,'' and (5) increased frequencies of formal dream features, including visual hallucination, self-representation, fictive movement, narrative plot, and bizarreness. While sleep-onset reports can include all features of rapid eye movement (REM) dream reports, the number of such features is markedly reduced at sleep onset, suggesting that this mentation is a greatly diminished version of REM dreaming.

We would like to thank Dolega and Dewhurst for a thought-provoking and informed deconstruction of our article, which we take as applause from valued members of our audience. In brief, we fully concur with the theatre-free formulation offered by Dolega and Dewhurst and take the opportunity to explain why we used the Cartesian theatre metaphor. We do this by drawing an analogy between consciousness and evolution. This analogy is used to emphasize the circular causality inherent in the free energy principle. We conclude with a comment on the special forms of active inference that may be associated with selfawareness and how they may be especially informed by dream states.

This study investigated the relationship between dream emotion and dream character identification. Thirty-five subjects provided 320 dream reports and answers to questions on characters that appeared in their dreams. We found that emotions are almost always evoked by our dream characters and that they are often used as a basis for identifying them. We found that affection and joy were commonly associated with known characters and were used to identify them even when these emotional attributes were inconsistent with those of the waking state. These findings are consistent with the finding that the dorsolateral prefrontal cortex, associated with short-term memory, is less active in the dreaming compared to the wake brain, while the paleocortical and subcortical limbic areas are more active. The findings are also consistent with the suggestion that these limbic areas have minimal input from the dorsolateral prefrontal cortex in the dreaming brain.

First published in 1914 and reissued with a new introduction in 1992, _Work and Wealth _is a seminal vision of Hobson's liberal utopian ideals, which desired to demonstrate how economic and social reform could transform existing society into one in which the majority of the population, as opposed to a small elite, could find fulfillment. Hobson attacked conventional economic wisdom which made a division between the cost of production and the utility derived from consumption. Far from being necesarily arduous, Hobson argued that work had the potential to bring about immense utility and enrichment. The qualitative, humanist work argues in favour of a new form of capitalism to minimise cost and maximise utility.

This paper presents a challenge to Eurocentric world history on the grounds that it reifies and exaggerates the role of the West in the creation of modernity, while simultaneously ignoring India's seminal contributions. The groundwork is prepared in the first three sections, which refute the parochial biases of Eurocentrism by revealing India's impressive early developmental record and its place near the center of a nascent global economy. The paper culminates in an approach that places the "dialogue of civilizations" center-stage of progressive world history, which is formulated as an antidote to parochial Eurocentric world history. This entails an extensive discussion of two key contributions that India made in enabling the rise of the modern West. These comprise the dissemination of Indian industrial methods that enabled the British industrial revolution on the one hand, and the transmission of Indian mathematical ideas that helped promote the European scientific revolution on the other hand. Moreover, this discussion is coupled with two speculative counterfactual historical scenarios. They are: first, that in the absence of British imperialism which sought to "contain" Indian development, India might have gone on to make the breakthrough to modernity, and second, that in the absence of Indian (as well as Chinese, African and Middle Eastern) help, the West might not have made the breakthrough to modernity. But whatever the veracity of such counterfactuals may or may not be, the ultimate upshot of the argument presented in this paper reveals that Eurocentrism's central claim - that the West made the breakthrough to modernity all by itself - can no longer hold true.

John Hobson claims that throughout its history most international theory has been embedded within various forms of Eurocentrism. Rather than producing value-free and universalist theories of inter-state relations, international theory instead provides provincial analyses that celebrate and defend Western civilization as the subject of, and ideal normative referent in, world politics. Hobson also provides a sympathetic critique of Edward Said's conceptions of Eurocentrism and Orientalism, revealing how Eurocentrism takes different forms, which can be imperialist or anti-imperialist, and showing how these have played out in international theory since 1760. The book thus speaks to scholars of international relations and also to all those interested in understanding Eurocentrism in the disciplines of political science/political theory, political economy/international political economy, geography, cultural and literary studies, sociology and, not least, anthropology.
