In the article discussed in this chapter, the authors describe a framework of neuroaesthetics for architectural experiences that considers sensory feedback stemming from movement central for the experience of the built environment. As we move through space when experiencing architecture, our sensory impressions change, rendering the body and the brain as nondissociable agents of aesthetic experience. This interaction is described by the term affordance. The authors cast the human experience of the built environment to be predicated on the functional relation between action and perception and developed a neuroscientific experiment on architectural transitions to investigate how the human brain reflects architectural affordances. They found that varying sizes of transitions, reflecting different affordances, impact early perceptual processes, suggesting that our perception is indeed colored by the action potentials afforded by the composed space. In conclusion, the shape of space resonates with our embodied predictions regarding movement.

The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language.

Recent advances in neurotechnology allow for an increasingly tight integration of the human brain and mind with artificial cognitive systems, blending persons with technologies and creating an assemblage that we call a hybrid mind. In some ways the mind has always been a hybrid, emerging from the interaction of biology, culture (including technological artifacts) and the natural environment. However, with the emergence of neurotechnologies enabling bidirectional flows of information between the brain and AI-enabled devices, integrated into mutually adaptive assemblages, we have arrived at a point where the specific examination of this new instantiation of the hybrid mind is essential. Among the critical questions raised by this development are the effects of these devices on the user’s perception of the self, and on the user’s experience of their own mental contents. Questions arise related to the boundaries of the mind and body and whether the hardware and software that are functionally integrated with the body and mind are to be viewed as parts of the person or separate artifacts subject to different legal treatment. Other questions relate to how to attribute responsibility for actions taken as a result of the operations of a hybrid mind, as well as how to settle questions of the privacy and security of information generated and retained within a hybrid mind.

This chapter discusses the clinical necessity from which the intersection of neurology and psychiatry arose, exploring different eras and their associated intellectual milestones in order to understand the historical framework of contemporary neuropsychiatry. Identifying Hippocrates’ original acknowledgement of the relation of the human brain to epilepsy as a start point, the historical development of the field is traced. This encompasses Thomas Willis and his nascent descriptions of the limbic system, the philosophical and alchemical strides of the Enlightenment, and the motivations behind the Romantic era attempts to understand the brain. It then follows the growth of the field through the turn of the twentieth century, in spite of the prominence of psychoanalysis and the idea of the brainless mind, and finally the understanding of the ‘integrated action’ of the body and nervous system, which led to the integration of psychiatry and neurology, allowing for the first neuropsychiatric examinations of epilepsy.

Summary Objectives: Survey current work primarily funded by the US Human Brain Project (HBP) that involves substantial use of images. Organize this work around a framework based on the physical organization of the body. Methods: Pointers to individual research efforts were obtained through the HBP home page as well as personal contacts from HBP annual meetings. References from these sources were followed to find closely related work. The individual research efforts were then studied and characterized. Results: The subject of the review is the intersection of neuroinformatics (information about the brain), imaging informatics (information about images), and structural informatics (information about the physical structure of the body). Of the 30 funded projects currently listed on the HBP web site, at least 22 make heavy use of images. These projects are described in terms of broad categories of structural imaging, functional imaging, and image-based brain information systems. Conclusions: Understanding the most complex entity known (the brain) gives rise to many interesting and difficult problems in informatics and computer science. Although much progress has been made by HBP and other neuroinformatics researchers, a great many problems remain that will require substantial informatics research efforts. Thus, the HPB can and should be seen as an excellent driving application area for biomedical informatics research.

This essay examines the much-contested “neuroscientific turn” in art history, taking the cues of the best of the turn while rejecting its false starts. The most promising transdisciplinary encounters spanning the brain sciences and the humanities begin from the premise that human experience is embodied, but the “body” itself is interwoven across biological, ecological, phenomenological, social and cultural planes. Certain media artworks critically engaged with neuroscience productively model such an approach. Taking Mariko Mori’s brainwave interface and multimedia installation Wave UFO (1999–2002) as a case study, the author explores how works of art may complicate and augment brain science research as well as its dissemination into other social and cultural arenas.

AbstractCan our brain perceive a sense of ownership towards an independent supernumerary limb; one that can be moved independently of any other limb and provides its own independent movement feedback? Following the rubberhand illusion experiment, a plethora of studies has shown that the human representation of ‘self’ is very plastic. But previous studies have almost exclusively investigated ownership towards ‘substitute’ artificial limbs, which are controlled by the movements of a real limb and/or limbs from which non-visual sensory feedback is provided on an existing limb. Here, to investigate whether the human brain can own an independent artificial limb, we first developed a novel independent robotic ‘sixth finger.’ We allowed participants to train using the finger and examined whether it induced changes in the body representation using behavioral as well as cognitive measures. Our results suggest that unlike a substituted artificial limb (like in the rubber hand experiment), it is more difficult for humans to perceive a sense of ownership towards an independent limb. However, ownership does seem possible, as we observed clear tendencies of changes in the body representation that correlated with the cognitive reports of the sense of ownership. Our results provide the first evidence to show that an independent supernumerary limb can be embodied by the human brain.

In this paper we look at the rational and the emotional interpretation of reality in the human brain and being, and discuss the representation of the brain-mind (ego), the body-mind (Id), and the outer world in the human wholeness (the I or “soul”). Based on this we discuss a number of factors including the coherence between perception, attention and consciousness, and the relation between thought, fantasies, visions and dreams. We discuss and explain concepts as intent, will, morals and ethics. The Jungian concept of the human collective conscious and unconscious is also analyzed. We also hypothesis on the nature of intuition and consider the source of religious experience of man. These phenomena are explained based on the concept of deep quantum chemistry and infinite dancing fractal spirals making up the energetic backbone of the world. In this paper we consider man as a real wholeness and debate the concepts of subjectivity, consciousness and intent that can be deduced from such a perspective.

The brain is the most sophisticated and intricate organ in the body. Billions of neurons interconnect and form distinct regions which process different neural activities. The development of the brain during pregnancy and early post-natal life is extremely sensitive, complex and crucial to proper function over the life of a person. This is the most plastic time of the brain. It is changing constantly and reacting to the different stimuli encountered by the individual. The lack of a particular stimulus can have a profound effect on the later structure and function of the brain. For example, if a newborn mouse has an eye covered so it receives no light, visual cortex, where normally processes binocular visual stimuli, develops to process visual stimuli only from the open eye. This cannot be altered later on even when both eyes are opened; the mouse remains weak in one eye despite there being nothing wrong with the eye itself. Studying this early time period of brain development presents many problems. Investigation is hampered by the difficulty in accessing and manipulating the brain as well as the huge variety of factors that contribute to brain development. Currently, most work is conducted in rodents, primarily because there are a large range of genetic tools available. This is useful to an extent and has demonstrated key findings that appear to be relevant to most mammalian species. However, the human brain is quite different to the mouse brain. It has adapted to very different tasks required of mice compared to humans and therefore there is a knowledge gap to bridge in this area. In addition to this, examination of global gene expression in the brain has only truly become viable in the last 10 years. The same can also be said of the ability to analyse the development process at a biochemical level. Dr Tomomi Shimogori of the RIKEN Center for Brain Science, Japan, has been tackling these difficulties through her work on the molecular mechanisms of brain development. She has worked on rodents, but is now developing a model in the common marmoset based around the creation of a gene atlas. Working on the primate should help fill in the gap between rodent and human. Shimogori explains why the marmoset was chosen: 'One of the biggest advantages of using marmosets as a model animal is that many of its behaviours share similarities with human behaviours, and thus has potential for use in understanding the underlying mechanisms of human brain function and mental disease

Science and art have long recognized that perceptual experience depends on the involvement of the experiencer. In art history, this idea is captured by Ernst Gombrich’s ‘beholder’s share’. In neuroscience, it traces to Helmholtz’s concept of ‘perception as inference’, which is enjoying renewed prominence in the guise of ‘prediction error minimization’ (PEM) or the ‘Bayesian brain’. The shared idea is that our perceptual experience – whether of the world, of ourselves, or of an artwork – depends on the active ‘top-down’ interpretation of sensory input. Perception becomes a generative act, in which perceptual, cognitive, affective, and sociocultural expectations conspire to shape the brain’s ‘best guess’ of the causes of sensory signals. In this article, I explore the parallels between the Bayesian brain and the beholders’ share, illustrated, somewhat informally, with examples from Impressionist, Expressionist, and Cubist art. By connecting phenomenological insights from these traditions with the cognitive neuroscience of predictive perception, I outline a reciprocal relationship in which art reveals phenomenological targets for neurocognitive accounts of subjectivity, while the concepts of predictive perception may in turn help make mechanistic sense of the beholder’s share. This is not standard neuroaesthetics – the attempt to discover the brain basis of aesthetic experience – nor is it any kind of neuro-fangled ‘theory of art’. It is instead an examination of one way in which art and brain science can be equal partners in revealing deep truths about human experience.

The introduction into medical practice of new methods of neuroimaging - computed and magnetic resonance imaging, has changed the principles of diagnosing morphological changes in the brain and opened up new horizons in the study of its structure. The literature sources provide conflicting and fragmentary data on the anatomical features and morphometric parameters of the parts of the brain, and especially its ventricular system, at different age periods of a person's life. The human brain is characterized by significant age-sex anatomical variability. It differs in men and women in different races, ethnic groups. Signs of difference persist from generation to generation and can be an important characteristic of the variability of the human brain as a species. However, the sex and age features of the structure of the cerebral ventricles, taking into account their individual anatomical variability, have not been sufficiently studied. During morphometric study of magnetic resonance tomograms a comprehensive in vivo characteristic of the cerebral ventricular system in elderly persons is presented. Gender peculiarities and inter-hemispheric asymmetry of relevant indicators are studied. The examinations were conducted in standard anatomical planes (sagittal, frontal and axial) in people with no visual signs of organic lesions of the brain and skull. 38 tomograms of elderly patients were analyzed 38 (14 men and 24 women). 13 indicators of the liquor system of the brain were studied and a significant increase of the following parameters were found in males: the length of the anterior horn of the right lateral ventricle, the length and width of the central part of the lateral ventricle both on the right and left, the length of the lower horn of the lateral ventricle on the left and right, and anterior-posterior size of the lateral ventricle on the right and left. Some of the parameters studied possessed reliable inter-hemispheric asymmetry, namely, in men on the left: the body width of the lateral ventricle, the length and width of the posterior horn of the lateral ventricle, anterior-posterior size of the lateral ventricle; in women – the length of the lower horn of the lateral ventricle on the right.
