Download or read book The spatiotemporal dynamics of longevity defining cellular processes and its modulation by genetic dietary and pharmacological anti aging interventions written by Vladimir I. Titorenko and published by Frontiers E-books. This book was released on with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging of multicellular and unicellular eukaryotic organisms is a highly complex biological phenomenon that affects a plethora of processes within cells. This wide array of longevity-defining cellular processes - which are governed by an evolutionarily conserved signaling network - includes oxidative metabolism and protein synthesis in mitochondria, lipid and carbohydrate metabolism, NAD+ homeostasis, amino acid biosynthesis and degradation, ammonium and amino acid uptake, ribosome biogenesis and translation, proteasomal protein degradation, nuclear DNA replication, chromatin assembly and maintenance, actin organization, apoptosis, necrosis, autophagy, protein folding, stress response, signal transduction, cell cycle, and cell growth. The focus of this Frontiers Special Topic Issue is on an important conceptual advance in our understanding of how cells integrate and control these numerous processes and how genetic, dietary and pharmacological anti-aging interventions extend longevity by altering their functional states and spatiotemporal dynamics. The Issue will highlight the various strategies used by evolutionarily diverse organisms for coordinating these longevity-defining cellular processes in space and time, critically evaluate the molecular and cellular mechanisms underlying such coordination, and outline the most important unanswered questions and directions for future research in this vibrant and rapidly evolving field.

Available in PDF, EPUB and Kindle. Book excerpt: Fifty years ago, enthused by successes in creating digital computers and the DNA model of heredity, scientists were con?dent that solutions to the problems of und- standing biological intelligence and creating machine intelligence were within their grasp. Progress at ?rst seemed rapid. Giant ‘brains’ that ?lled air-conditioned rooms were shrunk into briefcases. The speed of computation doubled every two years. What these advances revealed is not the solutions but the dif?culties of the pr- lems. We are like the geographers who ‘discovered’ America, not as a collection of islands but as continents seen only at shores and demanding exploration. We are astounded less by the magnitude of our discoveries about how brains cogitate than by the enormity of the tasks we have undertaken, to explain and replicate the higher functions of brains. Five decades of brain research have led to the emergence of a new ?eld, which spans the entire range of brain cognition from quantum ?elds to social interactions, and which is combined by the conceptions of nonlinear neurodynamics operating simultaneously at and across all levels. A new breed of scientists has emerged, schooled in multiple academic disciplines, comfortable in working with data from different levels, and conversant with the mathematical tools that are essential to cross boundaries.
Download or read book Volitional inhibition the gateway for an efficient control of voluntary movements written by Giovanni Mirabella and published by Frontiers E-books. This book was released on with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Being able to suppress a pending action is a fundamental ability for surviving in an unpredictable World. Sudden events, such as the appearance of a physical obstacle, might require a quick change of the planned motor strategy. The first step toward this goal is to suppress the pre-programmed actions. Understanding the functional characteristics and the neural underpinnings of inhibition is a primary aim, both for the treatment of such diseases as attention-deficit hyperactivity disorder, where the decision-making abilities are severely impaired, and for the development of efficient brain–machine interfaces. Despite an incredible amount of work, witnessed by tens of articles published on Medline, both the localizations of the neural substrates of voluntary inhibition and their specific contributions to this executive function are still controversial. However, the ability of vetoing pending actions is likely to be at the basis of self control and of mental simulation of voluntary actions. In other words the veto power is a cornerstone of our will. As such the neural code underling volitional inhibition should be taken into account to feed appropriate signals into artificial devices to mimic voluntary movements. The aim of the present Research Topic is twofold. On the one hand it will show the most innovative aspects of the current researches on the neural substrates and functional mechanisms of volitional inhibition. On the other hand it will deal with the possible applications of the acquired knowledge for building up interfaces that could collect and decode incoming neural signals in order to move artificial limbs and/or to interact with personal computers.

Download or read book The Crustacean Nervous System written by Konrad Wiese and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crustacean preparations have been successfully used for more than 50 years to investigate the principles which enable nerve cells and neural circuitry to perform in a wide variety of functions. The proud record of information of general significance obtained from crayfish and lobster nervous systems testifies that the use of an experimental system precisely matching theoretical and experimental requirements ofa measurement is an essential part of the success. In some respects, the secondarily diversified vertebrate and mammalian nervous systems pose severe obstacles to experimentation and measurement, whereas the crustacean nervous system recommends itself by being composed of individual neurons of unique morphology and physiology, which can be used repeatedly in several preparations. Moreover, a restricted number of invariantly displayed behaviors enable the experimenter to correlate neuron activity with parts of the behavior easier. Experts use these advantages to focus on a well-defined neuron and mechanism and to take a convincing measurement within a minimum amount oftime. In this book distinguished neurobiologists, the leading experts in the field, have joined efforts to present research using crustacean experimental systems. Thus they have contributed comprehensive information regarding a nervous system other than that ofvertebrates and mammalians, that ofcrustaceans. The accumulated knowledge on the crustacean nervous system shows that it is clearly divergent in evolution but functions in a similar way to neuronal circuitry found in the vertebrate system and can be used to interpret it.
Download or read book Magnetoencephalography an emerging neuroimaging tool for studying normal and abnormal human brain development written by Christos Papadelis and published by Frontiers Media SA. This book was released on 2015-10-12 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on the human brain development has seen an upturn in the past years mostly due to novel neuroimaging tools that became available to study the anatomy and function of the developing brain. Magnetic Resonance Imaging (MRI) and Diffusion Tensor Imaging (DTI) are beginning to be used more frequently in children to determine the gross anatomy and structural connectivity of their brain. Functional MRI and Near-Infrared Spectroscopy (NIRS) determine the hemodynamics and electroencephalography (EEG) the electrophysiological functions of the developing human brain. Magnetoencephalography (MEG) complements EEG as the only other technique capable of directly measuring the developing brain electrophysiology. Although MEG is still being used relatively rarely in pediatric studies, the recent development in this technology is beginning to demonstrate its utility in both basic and clinical neurosciences. MEG seems to be quite attractive for pediatric use, since it measures the human brain activity in an entirely passive manner without possessing any conceivable risk to the developing tissue. MEG sessions generally require minimal patient preparation, and the recordings are extremely well tolerated from children. Biomagnetic techniques also offer an indirect way to assess the functional brain and heart activity of fetuses in humans in utero by measuring the magnetic field outside the maternal abdomen. Magnetic field produced by the electrical activity in the heart and brain of the fetus is not attenuated by the vernix, a waxy film covering its entire skin. A biomagnetic instrument specifically designed for fetal studies has been developed for this purpose. Fetal MEG studies using such a system have shown that both spontaneous brain activity and evoked cortical activity can be measured from outside the abdomen of pregnant mothers. Fetal MEG may become clinically very useful for implementation and evaluation of intervention programs in at-risk populations. Biomagnetic instruments have also been developed for specifically measuring the brain activity in newborns, infants and older children. MEG studies have shown the usefulness of MEG for localizing active regions in the brain and also for tracking the longitudinal maturation of various sensory systems. Studies of pediatric patients are beginning to show interesting functional pathology in autism spectrum disorder, cerebral palsy, epilepsy and other types of neurological and psychiatric disorders (Down syndrome, traumatic brain injury, Tourette syndrome, hearing deficits, childhood migraine). In this eBook, we compile the state of the art MEG and other neuroimaging studies focused on pediatric population in both health and disease. We believe a review of the recent studies of human brain development using MEG is quite timely, since we are witnessing advances not only in the instrumentation optimized for the pediatric population, but also in the research based on various types of MEG systems designed for both human fetuses in utero and neonates and older children.

Download or read book The Role of Primary Motor Cortex as a Marker for and Modulator of Pain Control and Emotional Affective Processing written by Jorge Leite and published by Frontiers Media SA. This book was released on 2017-09-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sensory and motor cortical homunculi proposed by Walter Penfield were a major landmark for the anatomical mapping of the brain. More than 60 years after, the development of new tools to investigate brain function non-invasively has increased our knowledge about the structure and functions of the primary motor Cortex (M1) beyond motor control in both humans and animals. This book highlights the role of the motor cortex that goes way beyond motor functioning. We were interested in both theoretical and empirical contributions related to electrophysiological, pharmacological, neuroimaging, and neuromodulatory studies exploring the role of M1 on non-motor functions, such as pain, abnormal neuroplasticity that may lead to chronic pain conditions; or the relationship between M1 and mental imagery or emotion. This book is comprised of 15 articles published in this edited volume as a research topic collection in Frontiers in Human Neuroscience titled “The Role of Primary Motor Cortex as a Marker and Modulator of Pain Control and Emotional-Affective Processing.”
