Abstract

Mental chronometry encompasses all aspects of time processing in the nervous system and constitutes a standard tool in many disciplines including theoretical and experimental psychology and human neuroscience. Mental chronometry has represented a fundamental approach to elucidate the time course of many cognitive phenomena and their underlying neural circuits over more than a century. Nowadays, mental chronometry continues evolving and expanding our knowledge, and our understanding of the temporal organization of the brain in combination with different neuroscience techniques and advanced methods in mathematical analysis. In research on mental chronometry, human reaction/responses times play a central role. Together with reaction times, other topics in mental chronometry include vocal, manual and saccadic latencies, subjective time, psychological time, interval timing, time perception, internal clock, time production, time representation, time discrimination, time illusion, temporal summation, temporal integration, temporal judgment, redundant signals effect, perceptual, decision and motor time, etc. The aim of this research topic is to provide an overview of the state of the art in this field?its relevance, recent findings, current challenges, perspectives and future directions. Thus, as a result, a collection of 14 original research and opinion papers from different experts have been gathered together in a single volume.

Abstract

After decades of intensive research and over 10,000 publications, preterm birth remains a major global obstetric healthcare problem. Each year, early birth is responsible for the deaths of more than one million infants worldwide and is a major cause of life-long disability. Preterm birth places an enormous financial burden on our healthcare systems, resulting in long-term adverse health outcomes and lost productivity for many people. Preterm birth is a syndrome, associated with several different aetiologies; hence, potential treatment strategies need to be matched to pathophysiology in order to be effective. There is now unequivocal evidence that inflammation is causally involved in a majority of spontaneous preterm deliveries. However, the triggers of inflammation, and the strategies by which it can be safely and effectively prevented and treated, remain the subject of ongoing investigation and debate. While intraamniotic infection is an important cause of inflammation-associated preterm birth, particularly in very preterm deliveries, ‘sterile’ inflammation is actually a more common finding associated with preterm birth. It is likely that the nature, localisation, timing and extent of the inflammatory insult all determine the obstetric outcome and degree of risk to the fetus. These factors will also influence the success of approaches that might be employed to achieve better pregnancy outcomes. Despite our increased understanding of the causes and significance of intrauterine inflammation, we have yet to translate this knowledge into effective therapeutic strategies for preventing prematurity and mitigating its consequences for the neonate. In this Research Topic we review recent progress in treating and preventing inflammation-associated preterm birth, approaching the topic from both the causal and therapeutic perspectives. With global attention increasingly focused on the need to translate knowledge discovery into clinical translation, we hope this EBook will provide a stimulating and timely discussion that will focus research and lead to improved healthcare outcomes for women and children.

Abstract

Advances in modern sciences occur thanks to within-fields discoveries as well as confrontation of concepts and methods from separated, sometimes distant, domains of knowledge. For instance, the fields of psychology and psychopathology benefited from accumulated contributions from cognitive neurosciences, which, in turn, received insights from molecular chemistry, cellular biology, physics (neuroimaging), statistics and computer sciences (data processing), etc. From the results of these researches, one can argue that among the numerous cognitive phenomena supposedly involved in the emergence the human intelligence and organized behavior, some of them are specific to the social nature of our phylogenetic order. Scientific reductionism allowed to divide the social cognitive system into several components, i.e. emotion processing and regulation, mental state inference (theory of mind), agency, etc. New paradigms were progressively designed to investigate these processes within highly-controlled laboratory settings. Moreover, the related constructs were successful at better understanding psychopathological conditions such as autism and schizophrenia, with partial relationships with illness outcomes.

Abstract

This book offers a provocative account of interdisciplinary research across the neurosciences, social sciences and humanities. Setting itself against standard accounts of interdisciplinary 'integration,' and rooting itself in the authors' own experiences, the book establishes a radical agenda for collaboration across these disciplines. Rethinking Interdisciplinarity does not merely advocate interdisciplinary research, but attends to the hitherto tacit pragmatics, affects, power dynamics, and spatial logics in which that research is enfolded. Understanding the complex relationships between brains, minds, and environments requires a delicate, playful and genuinely experimental interdisciplinarity, and this book shows us how it can be done.

Abstract

People are progressively ageing all over the world, and it is estimated that the number of persons aged 60 or over will more than triple by 2100. This emerging population will experience an inevitable rise in dementia, mental health problems and chronic diseases. According to GBD (2010), neuropsychiatric disorders among older adults account for 6.6% of the total disability (DALYs) for this age group, with 15% suffering from a mental disorder. Multiple social, psychological and biological factors are determinant of mental health, as well as life stressors. Among these, the lack of independence, limited mobility, chronic diseases, pain, frailty or other mental and physical problems require long-term care. Beyond this, the elderly are more prone to experience events such as bereavement, a drop in socio-economic status, disability, which leads to isolation, loss of independence, loneliness and psychological distress. Mental health problems and needs assessment by health-care professionals and older people themselves are under-recognised, and the stigma surrounding mental illness makes people reluctant to seek help. The early investigation and diagnosis of these situations are crucial, as well as prior management with an important combination of pharmacological and psychosocial interventions, in conjunction with caregivers' and families' support. The present book aims to contribute to the development of knowledge in Aging and Mental Health, taking different approaches from authors, coming from diverse scientific fields, with the final goal being the improvement of quality of life and healthy aging for this growing population.

Abstract

Worldwide, 278 million people are estimated to have moderate to profound hearing loss. Age-related hearing loss, also known as presbyacusis, affects approximately half of the population over 60 years old, making it the second most common cause of disability in older people. Hearing loss occurs when the sensory cells and neurons of the cochlea degenerate and die. The vestibular system, which holds the sense of balance, shares a common embryonic origin with the cochlea and together conform the inner ear. Balance problems are a trait of ageing to the point that balance ability is considered a sensor of physical decline and vestibular degeneration is the most common cause of falls in the elderly. Still the molecular bases of ageing in the vestibular system have not been studied in detail. Genetic and environmental factors contribute to the progression of age-related hearing loss (ARHL). Being noise the main environmental noxious agent for human hearing in the industrialized societies. There is no restorative treatment for deafness but functional replacement by means of prosthesis. Therefore, prevention and treatment of hearing loss is an unmet medical need. To develop innovative medical strategies against hearing loss, it is critical to understand the causes of ARHL and the essential pathways responsible for the manifestation of this complex disease. In this research topic, experts will discuss the stages and molecular elements of the damage and repair processes involved in ARHL, from cellular processes to molecules involved in aging. Oxidative stress takes a central stage as an essential element in the progression of injury and cell loss, and a target for cell protection strategies. Finally, the mechanisms of action and the potential of novel therapies for hair cell repair and protection will be discussed along with drug delivery strategies.

Abstract

The vertebrate brain contains neurons and 3 classical types of glia cells, astrocytes, oligodendrocytes and microglia. Astrocytes and microglia have mainly been studied in gray matter, whereas oligodendrocytes myelinate white matter tracts. Until recently microglial effects were considered mainly during pathological conditions, but is now known that microglia plays important roles also in normal brain function. All these 3 glial cell types and their collaboration with neurons are important for learning. The concept that glia cells are important for cognitive function is not new. A glial-neuronal theory of brain function was proposed by Galambos in 1961. Hyden and Egyhazi demonstrated glial RNA changes in microdissected glia cells during learning in rats in 1963, and astrocytic and oligodendrocytic involvement of K+-mediated effects of learning has been suggested and/or demonstrated from the 1960’s and onwards as recently reviewed by Hertz and Chen (Neuroscience and Biobehavioural Reviews, 2016). In 1969 van den Berg et al. showed compartmentation of glutamate in brain and thus of production of the neurotransmitters glutamate and GABA, which are essential for learning. That glutamate is synthesized in astrocytes because they in contrast to neurons express the enzyme pyruvate carboxylase was demonstrated 10-15 years later by Yu et al. in cultured astrocytes and Shank et al. in intact brain tissue. However, the present e-book focuses on more recent developments. Most information is available about astrocytic roles in learning. The importance of astrocytes in the tripartite synapse and of microglia in the tetrapartite synapse is illustrated in the front-page figure, which emphasizes the role of gliotransmitters and of Ca2+ transport through gap junctions, coupling astrocytes into a functional syncytium. Astrocytes are important for establishments of brain rhythms, which may differ in different cognitive tasks, and although the exact reason why knock-out of the astrocytic water channel AQP4 impairs memory remains to be established, several possibilities are discussed. The importance of the two astrocyte specific processes glutamate and glutamine formation and glycogenolysis is discussed in considerable detail. Glycogenolysis is important not only for astrocytic processes involved in learning, but also for those in neurons because glycolytically derived lactate has signaling functions in the extracellular space and may be accumulated in minute quantities into very specific and small neuronal structures. Some neurotransmitters stimulating glycogenolysis are also involved in psychiatric disease. Noradrenaline, released from locus coeruleus exerts direct effects on both astrocytes and neurons and in addition promotes secretion of corticotropin-releasing hormone and adrenocorticotrophic hormone (ACTH) in brain, and of glucocorticoids from the adrenal cortex, all of which are responsible for stress effects on learning. Lead causes memory impairment by inhibition of glutamine formation due to oxidative stress and reduced effectiveness of the glutathione system. The many adverse effects of fetal alcohol exposure on behaviour and learning are caused by a multitude of effects on all three types of glia cells. Traumatic brain injury also exerts multifactorial effects, including microglia/astrocyte-induced secretion of neuroinflammatory molecules and axonal disruption and oligodendrocytic dysfunction. In normal brain oligodendrocytes respond to the depolarization caused by neuronal activity with accelerated conduction velocity and increased compound action potentials which facilitate learning.

Abstract

Alzheimer's disease was discovered over 100 years ago and still belongs to incurable neurological diseases; its pharmacotherapy is considered to be ineffective. This book presents contemporary views on the genetic, biochemical, and immunological determinants of this disease. This book also concerns the issue of Alzheimer's disease prevention through lifestyle and physical activity. Moreover, it describes the therapies used in Alzheimer's disease to slow the progression of the disease and delay its onset. Subsequently, the authors discuss experimental and clinical trials used now and in the near future. We hope that this book will help the readers to understand the complex mechanism leading to the development of Alzheimer's disease and indicate effective ways to prevent this disorder.
