This chapter discusses true holograms as a “remix” discussion from Chapter 4 of ghosts out of the post-screen. Commonly confused with holographic projections, true holograms are two-dimensional images naturally viewed (i.e. without optical aids) as 3-dimensional objects. Leveraging theoretical sources such as Deleuze’s notion of “the brain is the screen” and Vilém Flusser’s ideas of point culture and linearity, the chapter argues for the post-screen through the true hologram whose ghosts are not of the spectral return of the dead, but digital apparitions via which the human mind ideates and projects realities. These digital ghosts thus return with a necromancy of their own on the terms of zerodimensionality and post-rationality, confronting us with new problems of reality and questions about ourselves.

Abstract BACKGROUND: Accurate placement of a probe to the deep regions of the brain is an important part of neurosurgery. In the modern era, magnetic resonance image (MRI)-based target planning with frame-based stereotaxis is the most common technique. OBJECTIVE: To quantify the inaccuracy in MRI-guided frame-based stereotaxis and to assess the relative contributions of frame movements and MRI distortion. METHODS: The MRI-directed implantable guide-tube technique was used to place carbothane stylettes before implantation of the deep brain stimulation electrodes. The coordinates of target, dural entry point, and other brain landmarks were compared between preoperative and intraoperative MRIs to determine the inaccuracy. RESULTS: The mean 3-dimensional inaccuracy of the stylette at the target was 1.8 mm (95% confidence interval [CI], 1.5-2.1. In deep brain stimulation surgery, the accuracy in the x and y (axial) planes is important; the mean axial inaccuracy was 1.4 mm (95% CI, 1.1-1.8). The maximal mean deviation of the head frame compared with brain over 24.1 ± 1.8 hours was 0.9 mm (95% CI, 0.5-1.1). The mean 3-dimensional inaccuracy of the dural entry point of the stylette was 1.8 mm (95% CI, 1.5-2.1), which is identical to that of the target. CONCLUSION: Stylette positions did deviate from the plan, albeit by 1.4 mm in the axial plane and 1.8 mm in 3-dimensional space. There was no difference between the accuracies at the dura and the target approximately 70 mm deep in the brain, suggesting potential feasibility for accurate planning along the whole trajectory.

In this paper I discuss some aspects of the problem of carriers of human mind and person. The main emphasis is placed on the origin of our idea of the identi­cal self in the stream of perceptions, the need for a physical carrier of our self and person, and on possibility of replacing the biological carriers of self and per­son with artificial analogues. I argue that the idea of identical self is constructed by reflection on memories, that its truth is guaranteed by continuous stream of perceptions kept in memories, and that the stream of perceptions presupposes the presence of a normally functioning brain, which can be considered as a car­rier of our mind and person. Therefore, personal identity turns out to be depen­dent on the identity of the brain in time. An attempt to copy the structures of mind and person onto other possible carriers can thus only lead to creation of duplicates of the original person, but not to the continuation of its existence on another carrier. I argue that the gradual replacement of their components with artificial analogues is a more promising way of transforming the biological carri­ers of human person. To access the possible consequences of such a replacement I analyze arguments of John Searle and David Chalmers, designed to show, re­spectively, the disappearance of consciousness and person with such a replace­ment and, on the contrary, their preservation in a previous state. I explain why Searle’s arguments are unconvincing, and demonstrate that Chalmers’ arguments are based on a hidden premise, the confirmation of which is possible in the con­text of dubious theories of mind-body identity, epiphenomenalism or panpsy­chism only. I conclude that in the current situation it is impossible to predict which consequences for our person would follow such a replacement.

Emotions are at the heart of how we understand the human mind and of our relationships within the social world. Yet, there is still no scientific consensus on the fundamental nature of emotion. A central quest within the discipline of affective science is to develop an in-depth understanding of emotions, moods, and feelings and how they are embodied within the brain (affective neuroscience). This article provides a brief overview of the scientific study of emotion with a particular emphasis on psychological and neuroscientific perspectives. Following a selective snapshot of past and present research in this field, some current challenges and controversies in affective science are highlighted.

The biological study of man is one of today's most rapidly advancing sciences. There is no reason for not utilizing these methodologies of research and the knowledge already gained when studying ecstasy and other similar religious phenomena. Drugs have been used in all parts of the world as an ecstasy technique. Since mental states and physiological correlates always accompany each other, it is obvious that the human mind can be affected by external means, for instance by drugs. But the opposite is also true; mental changes affect the body, as they do in the case of psychosomatic diseases. Ecstasy is often described as an extremely joyful experience; this pleasure must necessarily also have a physiological basis. It is of course too early to say anything for certain, but the discovery of pleasure centres in the brain might offer an explanation. It is not far-fetched to suggest that when a person experiences euphoric ecstasy, it might, in some way or other, be connected with a cerebral pleasure center. Can it be, for example, that religious ecstasy is attained only by some mechanism triggering off changes in the balance of the transmitter substances? Or is it reached only via a change in the hormonal balance, or only by a slowing down of the brain waves, or is a pleasure centre activated? When a person is using an ecstasy technique, he usually does so within a religious tradition. When he reaches an experience, a traditional interpretation of it already exists.

The study in this paper are explain about the studies of medical (medicine) blood type have the same relationship to human character because the blood producing antibodies and antigens. It could determine a person helpless hold strong or weak body, has an allergy to something or not, in the blood also contains various nutrients (like protein) and also the oxygen being supplied to the brain and nerves and body affect performance someone will then be emanated from the attitude of the person and social interaction. As has been explained, but keep in mind, there is blood in the genes, the nature of which is carried in the body/genotif rightly so it is, but we can not ignore the fenotif/nature arising or visible, this trait appear due to interaction between genes and the environment, so even if the person is smart in the intelligentsia and emotional, but grew up in a bad environment is going to be a bad trait. The theory of personality based on blood type can be used as a reference in parenting children through an understanding of the fundamental principles of the application of personality accompanied by parenting. Furthermore, the taking of steps in the care tailored to the stage of development of the child, in the Qur'an explicitly did not mentioned paragraph that discusses about blood type, but in the Qur'an there are blood (ad-Dam), Islamic studies in the study of Children is seen as a mandate from God, forming 3-dimensional relationships, with parents as the central figure. First, her parents relationship with God that is backed by the presence of children. Second, the relationship of the child (which still need a lot of guidance) with God through his parents. Third, the relationship of the child with both parents under the tutelage and guidance of God.
