Download or read book Investigating the Attentional Effects of Acute Aerobic Exercise and Crossmodal Processing on the Modulation of Frontoparietal Interactions written by Christina Popovich and published by . This book was released on 2015 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sense of touch commences when afferent sensory signals from the periphery ascend via the spinal cord to the cortex. At the cortical level, incoming peripheral signals are susceptible to neuronal modulation at the primary somatosensory cortex; the principle region responsible for tactile perception. This modulation is largely influenced by two attentional mechanisms: 1) Bottom-up attention whereby salient stimuli automatically capture attention; and/or, 2) Top-down or selective attention, whereby relevant sensory signals are voluntarily selected for in-depth cognitive processing, while irrelevant signals are ignored. Selective attention to both task-relevant stimuli as well as to crossmodal sensory interactions can facilitate neuronal responses at very early stages in modality-specific sensory regions. Efforts to understand the mechanisms underlying top-down attention suggest that the prefrontal cortex (PFC) has a critical role in the modulation of modality-specific regions by gating or suppressing irrelevant sensory information. Recent evidence suggests that an acute bout of moderate intensity aerobic exercise upregulates PFC excitability thereby facilitating cognitive tasks requiring top-down attentional control, particularly in older populations. However, the specific contribution of each sensory system during attentional processing and, importantly, how these interact with the required behavioural motor goals remains unclear. It is also unclear whether acute bouts of moderate intensity aerobic exercise modulate cortical regions downstream from the PFC, such as the somatosensory cortex. This thesis will aim to address these questions in order to gain a better understanding of the neural mechanisms underlying somatosensory processing, and whether aerobic exercise can be used as a plausible intervention strategy for sensory processing impairments that are often associated with normal aging.
Download or read book Working Memory Capacity written by Nelson Cowan and published by Psychology Press. This book was released on 2016-04-14 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of one's memory "filling up" is a humorous misconception of how memory in general is thought to work; it actually has no capacity limit. However, the idea of a "full brain" makes more sense with reference to working memory, which is the limited amount of information a person can hold temporarily in an especially accessible form for use in the completion of almost any challenging cognitive task. This groundbreaking book explains the evidence supporting Cowan's theoretical proposal about working memory capacity, and compares it to competing perspectives. Cognitive psychologists profoundly disagree on how working memory is limited: whether by the number of units that can be retained (and, if so, what kind of units and how many), the types of interfering material, the time that has elapsed, some combination of these mechanisms, or none of them. The book assesses these hypotheses and examines explanations of why capacity limits occur, including vivid biological, cognitive, and evolutionary accounts. The book concludes with a discussion of the practical importance of capacity limits in daily life. This 10th anniversary Classic Edition will continue to be accessible to a wide range of readers and serve as an invaluable reference for all memory researchers.

Download or read book Physical Activity and the Aging Brain written by Ronald Ross Watson and published by Academic Press. This book was released on 2016-12-15 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical Activity and the Aging Brain: Effects of Exercise on Neurological Function is a complete guide to the manifold effects of exercise and physical activity on the aging brain. Cognitive decline and motor impairment, onset of diseases and disorders, and even changes in family structure and social settings that occur as we age can all impact activity levels, yet continued physical activity is crucial for successful neurological functioning. This book examines the role that exercise and physical activity play in halting or modulating the deleterious effects of these numerous aging concerns by first examining the current state of research into how exercise manifests physical changes in the brain. It then discuss how physical activity combines with other lifestyle factors to benefit the aging brain, including nutrition, computerized brain training, and social engagement. Most significantly, it also covers how physical activity can serve as therapy to help alleviate the symptoms of various neurological diseases impacting aging populations, with particular emphasis on Alzheimer’s disease and age-related cognitive decline. The book provides broad coverage of the effects of exercise and physical activity on the aging brain, its therapeutic effects, and the many factors that influence the aging process. Presents research scientists with a complete understanding of the role of exercise in healthy brain aging Considers the roles of nutrition, the mind-body connection, and other lifestyle factors Presents a major resource for exercise and physical activity in the neurological health of older adults Provides a synopsis of key ideas associated with the many aspects of physical activity, along with lifestyle factors that can modify neurological diseases and age-related neurological decline

Download or read book Cognitive Training written by Tilo Strobach and published by Springer. This book was released on 2016-11-16 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a cutting edge international team of contributors to critically review the current knowledge regarding the effectiveness of training interventions designed to improve cognitive functions in different target populations. There is substantial evidence that cognitive and physical training can improve cognitive performance, but these benefits seem to vary as a function of the type and the intensity of interventions and the way training-induced gains are measured and analyzed. This book further fulfills the need for clarification of the mechanisms underlying cognitive and neural changes occurring after training. This book offers a comprehensive overview of empirical findings and methodological approaches of cognitive training research in different cognitive domains (memory, executive functions, etc.), types of training (working memory training, video game training, physical training, etc.), age groups (from children to young and older adults), target populations (children with developmental disorders, aging workers, MCI patients etc.), settings (laboratory-based studies, applied studies in clinical and educational settings), and methodological approaches (behavioral studies, neuroscientific studies). Chapters feature theoretical models that describe the mechanisms underlying training-induced cognitive and neural changes. Cognitive Training: An Overview of Features and Applications will be of interest to researchers, practitioners, students, and professors in the fields of psychology and neuroscience.
Download or read book Biophysics and Neurophysiology of the Sixth Sense written by Nima Rezaei and published by Springer. This book was released on 2019-04-26 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple senses, like multiple intelligences, are a key to brain variability and therefore human evolution. Besides the traditional five senses (vision, olfaction, gustation, audition, and somatosensory), humans can also perceive the body’s own position (the sense of proprioception) and movement (the vestibular sense). Interoception is the feeling one has about the internal physiological conditions of the entire body. Additionally there is a sense of intuition, also known as the sixth sense. Despite their best efforts, researchers are still unable to concur in specifying the nature of the sixth sense; some consider the sense of proprioception as the sixth sense, whereas others prefer to consider that as a part of interoception. This book will provide a scientific system for the human sixth sense using relevant biophysical and neurophysiological evidence. The power of “sixth sense” seems to be underestimated, due to difficulties in defining the concept clearly. According to socioeconomics and neural physics, the sixth sense is that which permits humans to create perception or to enhance the quality of their perception of events. Roughly speaking, the sixth sense engages a metacognitive process through which prior knowledge and the information received from other sensory modalities are synergized. It is not restricted to specific arrow of time and type of mind or to the observer’s body, but it considers all arrows of time (past, present, future), types of mind (conscious and unconscious), and physical bodies (self and other). However it is expected that the observer has specific biases towards what happens now or would happen in the future and its relation to himself. Particularly, humans appeal to the sixth sense on the road to achieving success in social competitions and to reduce uncertainty in complex decision making processes. In addition to evidence linking genetic components to the sixth sense submodalities, there have been developed strategies for increasing the quality of perceptions provided by the sixth sense. Meditation, through which individuals try to be detached from the world, increases gamma-band activity and that increased gamma-band activity is found following top-down processing. Therefore it can be inferred that the detachment from the environment may enhance synchronization of the wave functions in favor of strengthening the sixth sense. It can serve as the mechanism of enhancement of the sixth sense in those whose sensory systems are intact, it can also serve as the mechanism of compensation in those who have sensory deficiencies. In the latter case, it in fact encourages creativity in the use of relatively strong senses. This justifies Beethoven's deafness and his great musical creativity or Bramblitt's blindness and his enormous capability to paint and many other similar examples. In summary, the present book is divided into five parts. Part 1 (chapters 1-6) provides information about the system of proprioception and its neurophysiology and biophysics. Part 2 (chapters 7-10) examines the system of interoception. The information provided in these two parts would enable us to move towards the next three parts of the story, aimed at developing a scientific system of the sixth sense. The first chapter of part 3 begins with concepts and uses them to arrive at reasonable conclusion that there must be a sense that requires multistep information processing and that is separate from the sense of proprioception and the sense of interoception. Such sense is commonly known as the sixth sense. However it should be re-numbered because the sense of proprioception is already known as the sixth sense. The second chapter of this part is to draw neurocircuitry that innervates the sixth sense in the mind of a man, while the third chapter would address the questions whether the sixth sense system requires an optimal competence or consciousness of mind to function properly and if so which is the optimal state: conscious or unconscious and competence or incompetence. In the fourth chapter of this part, we will focus on the self-other mergence as a pivotal step of the sixth sense system. The next chapter would be of great interest to neurobiologists. It talks about that the human sixth sense of the unseen world, either the unseen arrow of time or the unseen events, requires creativity and therefore the human sixth sense should be considered a source of creativity, variability and thus evolution. In the sixth chapter, the sixth sense is viewed as an economic activity stimulated by social environments. This chapter arisen from the fact that humans are full of enthusiasm to heighten their sixth sense and its accuracy and that they owe their enthusiasm largely to achieving the best possible profit and in other words to wining intense competitions in their life holds mainly on the concept of elasticity. Finally this part is finished by an amazing discussion on the art of the sixth sense. The first chapter of part 4 discusses physical theories that support the existence of sixth sense in the universe. The next chapter is to apply the Bayes’ theory to the sixth sense, leading to the conclusion that the sixth sense improves multisensory integration through optimizing uncertainty of information received from other sensory modalities. Chapter three in this part would address whether relative timing is applicable to the sixth sense like other senses. The last part of book aimed at directly discussing the sixth sense into the context of human health and behavior is organized into four chapters. The first chapter is to discuss neurodevelopmental changes in the sixth sense, while the second and third ones will discuss that in relation to psychiatric and neurological disorders. The most striking question how much power the sixth sense the sixth sense have over human health and behavior is addressed in the fourth chapter of this part and final chapter of book, which will be prepared using neural network models and sophisticated portraits possible for the system of sixth sense.
Download or read book Neuro Education and Neuro Rehabilitation written by Eduardo Martínez-Montes and published by Frontiers Media SA. This book was released on 2016-11-04 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, important discoveries have been made in cognitive neuroscience regarding brain plasticity and learning such as the mirror neurons system and the anatomo-functional organization of perceptual, cognitive and motor abilities.... Time has come to consider the societal impact of these findings. The aim of this Research Topic of Frontiers in Psychology is to concentrate on two domains: neuro-education and neuro-rehabilitation. At the interface between neuroscience, psychology and education, neuro-education is a new inter-disciplinary emerging field that aims at developing new education programs based on results from cognitive neuroscience and psychology. For instance, brain-based learning methods are flourishing but few have been rigorously tested using well-controlled procedures. Authors of this Research Topic will present their latest findings in this domain using rigorously controlled experiments. Neuro-rehabilitation aims at developing new rehabilitation methods for children and adults with learning disorders. Neuro-rehabilitation programs can be based upon a relatively low number of patients and controls or on large clinical trials to test for the efficiency of new treatments. These projects may also aim at testing the efficiency of video-games and of new methods such as Trans Magnetic Stimulation (TMS) for therapeutic interventions in children or adolescents with learning disabilities. This Research Topic will bring together neuroscientists interested in brain plasticity and the effects of training, psychologists working with adults as well as with normally developing children and children with learning disabilities as well as education researchers directly confronted with the efficiency of education programs. The goal for each author is to describe the state of the art in his/her specific research domain and to illustrate how her/his research findings can impact education in the classroom or rehabilitation of children and adolescents with learning disorders.

Download or read book Brain and Art written by Bruno Colombo and published by Springer Nature. This book was released on 2019-08-29 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes and discusses in detail art therapy, a specific tool used to sustain health in affective developments, rehabilitation, motor skills and cognitive functions. Art therapy is based on the assumption that the process of making art (music, dance, painting) sparks emotions and enhances brain activity. Art therapy is used to encourage personal growth, facilitate particular brain areas or activity patterns, and improve neural connectivity. Treating neurological diseases using artistic strategies offers us a unique option for engaging brain structural networks that enhance the brain’s ability to form new connections. Based on brain plasticity, art therapy has the potential to increase our repertoire for treating neurological diseases. Neural substrates are the basis of complex emotions relative to art experiences, and involve a widespread activation of cognitive and motor systems. Accordingly, art therapy has the capacity to modulate behavior, cognition, attention and movement. In this context, art therapy can offer effective tools for improving general well-being, quality of life and motivation in connection with neurological diseases. The book discusses art therapy as a potential group of techniques for the treatment of neurological disturbances and approaches the relationship between humanistic disciplines and neurology from a holistic perspective, reflecting the growing interest in this interconnection.
Download or read book Visual Mismatch Negativity vMMN a Prediction Error Signal in the Visual Modality written by Gabor Stefanics and published by Frontiers Media SA. This book was released on 2015-06-04 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current theories of visual change detection emphasize the importance of conscious attention to detect unexpected changes in the visual environment. However, an increasing body of studies shows that the human brain is capable of detecting even small visual changes, especially if such changes violate non-conscious probabilistic expectations based on repeating experiences. In other words, our brain automatically represents statistical regularities of our visual environmental. Since the discovery of the auditory mismatch negativity (MMN) event-related potential (ERP) component, the majority of research in the field has focused on auditory deviance detection. Such automatic change detection mechanisms operate in the visual modality too, as indicated by the visual mismatch negativity (vMMN) brain potential to rare changes. VMMN is typically elicited by stimuli with infrequent (deviant) features embedded in a stream of frequent (standard) stimuli, outside the focus of attention. In this research topic we aim to present vMMN as a prediction error signal. Predictive coding theories account for phenomena such as mismatch negativity and repetition suppression, and place them in a broader context of a general theory of cortical responses. A wide range of vMMN studies has been presented in this Research Topic. Twelve articles address roughly four general sub-themes including attention, language, face processing, and psychiatric disorders. Additionally, four articles focused on particular subjects such as the oblique effect, object formation, and development and time-frequency analysis of vMMN. Furthermore, a review paper presented vMMN in a hierarchical predictive coding framework. Each paper in this Research Topic is a valuable contribution to the field of automatic visual change detection and deepens our understanding of the short term plasticity underlying predictive processes of visual perceptual learning.
Download or read book How Do You Feel written by A. D. Craig and published by Princeton University Press. This book was released on 2014-12-21 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book that fundamentally changes how neuroscientists and psychologists categorize sensations and understand the origins and significance of human feelings How Do You Feel? brings together startling evidence from neuroscience, psychology, and psychiatry to present revolutionary new insights into how our brains enable us to experience the range of sensations and mental states known as feelings. Drawing on his own cutting-edge research, neurobiologist Bud Craig has identified an area deep inside the mammalian brain—the insular cortex—as the place where interoception, or the processing of bodily stimuli, generates feelings. He shows how this crucial pathway for interoceptive awareness gives rise in humans to the feeling of being alive, vivid perceptual feelings, and a subjective image of the sentient self across time. Craig explains how feelings represent activity patterns in our brains that signify emotions, intentions, and thoughts, and how integration of these patterns is driven by the unique energy needs of the hominid brain. He describes the essential role of feelings and the insular cortex in such diverse realms as music, fluid intelligence, and bivalent emotions, and relates these ideas to the philosophy of William James and even to feelings in dogs. How Do You Feel? is also a compelling insider's account of scientific discovery, one that takes readers behind the scenes as the astonishing answer to this neurological puzzle is pursued and pieced together from seemingly unrelated fields of scientific inquiry. This book will fundamentally alter the way that neuroscientists and psychologists categorize sensations and understand the origins and significance of human feelings.
Download or read book Handbook of Executive Functioning written by Sam Goldstein and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planning. Attention. Memory. Self-regulation. These and other core cognitive and behavioral operations of daily life comprise what we know as executive functioning (EF). But despite all we know, the concept has engendered multiple, often conflicting definitions and its components are sometimes loosely defined and poorly understood. The Handbook of Executive Functioning cuts through the confusion, analyzing both the whole and its parts in comprehensive, practical detail for scholar and clinician alike. Background chapters examine influential models of EF, tour the brain geography of the executive system and pose salient developmental questions. A section on practical implications relates early deficits in executive functioning to ADD and other disorders in children and considers autism and later-life dementias from an EF standpoint. Further chapters weigh the merits of widely used instruments for assessing executive functioning and review interventions for its enhancement, with special emphasis on children and adolescents. Featured in the Handbook: The development of hot and cool executive function in childhood and adolescence. A review of the use of executive function tasks in externalizing and internalizing disorders. Executive functioning as a mediator of age-related cognitive decline in adults. Treatment integrity in interventions that target executive function. Supporting and strengthening working memory in the classroom to enhance executive functioning. The Handbook of Executive Functioning is an essential resource for researchers, scientist-practitioners and graduate students in clinical child, school and educational psychology; child and adolescent psychiatry; neurobiology; developmental psychology; rehabilitation medicine/therapy and social work.

Download or read book Attention and Performance XVII written by Daniel Gopher and published by MIT Press. This book was released on 1999 with total page 842 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1966 the first meeting of the Association for the Study of Attention and Performance was held in the Netherlands to promote the emerging science of cognitive psychology. This volume is based on the most recent conference, held in Israel thirty years later. The focus of the conference was the interaction between theory and application. The organizers chose the specific topic, cognitive regulation of performance, because it is an area where contemporary theories of cognitive processes meet the everyday challenges posed by human interactions with complex systems. Present-day technological systems impose on the operator a variety of supervisory functions, such as input and output monitoring, allocation of cognitive resources, choice of strategies, and regulation of cognitive operations. A challenge for engineers and designers is to accommodate the cognitive requirements called for by these systems. The book is divided into four sections: the presentation and representation of information, cognitive regulation of acquisition and performance, consciousness and behavior, and special populations: aging and neurological disorders.
