Book Description
A World From Dust describes how a set of chemical rules combined with the principles of evolution in order to create an environment in which life as we know it could unfold. Beginning with simple mathematics, these predictable rules led to the advent of the planet itself, as well as cells, organs and organelles, ecosystems, and increasingly complex life forms. McFarland provides an accessible discussion of a geological history as well, describing how the inorganic matter on Earth underwent chemical reactions with air and water, allowing for life to emerge from the world's first rocks. He traces the history of life all the way to modern neuroscience, and shows how the bioelectric signals that make up the human brain were formed. Most popular science books on the topic present either the physics of how the universe formed, or the biology of how complex life came about; this book's approach would be novel in that it condenses in an engaging way the chemistry that links the two fields. This book is an accessible and multidisciplinary look at how life on our planet came to be, and how it continues to develop and change even today. This book includes 40 illustrations by Gala Bent, print artist and studio faculty member at Cornish College of the Arts, and Mary Anderson, medical illustrator.

Book Description
Neuroplasticity refers to the ability of the Central Nervous System (CNS) to alter its structure and function in response to a variety of physiological and pathological processes such as development, cognition, injury or neurological diseases. Since more than four decades, studies on synaptic plasticity in the context of memory and learning attracted a remarkable interest. Soon after first seminal works on synaptic plasticity were published, research in this field was extended by studies on non-synaptic as wells as structural plasticity towards a goal to understand cellular and molecular determinants of cognition. Over the past two decades, yet two additional crucial players in neuroplastic phenomena started to be intensely investigated – glial cells and the extracellular matrix (ECM). Growing awareness that glial cells, especially astrocytes, are important regulators of synaptic functions gave rise to a novel concept of a tri-partite synapse. Also, over the last two decades, a growing body of evidence has accumulated that the extracellular matrix (ECM) in the brain is strongly involved in regulation of neurons, in particular, in synaptic plasticity. Thus, a concept of tetra-partite synapse was put forward by some neuroscientists. The cross-talk between neuron-glia-ECM system involves enzymatic degradation of proteins or peptides and amino acids occurring in each of these brain constituents by means of a variety of proteases. Importantly, it has been realized that proteases such as serine proteases and matrix metalloproteinases, not only accompany “robust” phenomena such as cell division, or development or neurodegnerative conditions but may play a very subtle signaling functions, particularly important in memory acquisition. Indeed, the repertoire of substrates for these enzymes covers a wide variety of proteins known to play important role in the neuroplastic phenomena (e.g. BDNF, TNF-a, ephrin systems, various cell adhesion molecules, etc.). In result, the role of metalloproteinases and such serine proteases as tissue plasminogen activator (tPA), neuropsin or neurotrypsin in synaptic plasticity as well as in learning and memory has been particularly well demonstrated. It needs to be emphasized, however, that in spite of a remarkable progress in this field, several basic questions regarding molecular and cellular mechanisms remain unanswered. Potential involvement of so many important players (various proteases and their substrates in neurons, glia and in ECM) points to an enormous potential for plasticity phenomena but makes also studies into underlying mechanisms particularly difficult. In the proposed Research Topic we provide both review of the current state of the art and present some original reports on specific aspects of the role of proteolysis in neuroplasticity phenomena. The present ebook starts with extensive reviews describing involvement of proteolysis not only in synaptic plasticity but also in regulating endogenous excitability and structural changes at the network, cellular and subcellular levels. Cross-talk between neuroplasticity and proteolysis is also emphasized in the context of development and in relation to various pathologies. Whereas in the first part of the present ebook, the major focus is on metalloproteinases, the successive articles address the role of neuropsin and thrombin. The Research Topic is concluded with a series of articles describing the components of extracellular matrix and adhesion proteins and their elaboration by mechanisms dependent directly or indirectly on proteolysis. We do hope that the present ebook will further stimulate the interest in the fascinating investigations into neuroplasticity-proteolysis cross-talk.

Book Description
Learning and memory are believed to depend on plastic changes of neuronal circuits due to activity-dependent potentiation or depression of specific synapses. During the last two decades, plasticity of brain circuits was hypothesized to mainly rely on the flexibility of glutamatergic excitatory synapses, whereas inhibitory synapses were assumed relatively invariant, to ensure stable and reliable control of the neuronal network. As a consequence, while considerable efforts were made to clarify the main mechanisms underlying plasticity at excitatory synapses, the study of the cellular/molecular mechanisms of inhibitory plasticity has received much less attention. Nevertheless, an increasing body of evidence has revealed that inhibitory synapses undergo several types of plasticity at both pre- and postsynaptic levels. Given the crucial role of inhibitory interneurons in shaping network activities, such as generation of oscillations, selection of cell assemblies and signal integration, modifications of the inhibitory synaptic strength represents an extraordinary source of versatility for the fine control of brain states. This versatility also results from the rich diversity of GABAergic neurons in several brain areas, the specific role played by each inhibitory neuron subtype within a given circuit, and the heterogeneity of the properties and modulation of GABAergic synapses formed by specific interneuron classes. The molecular mechanisms underlying the potentiation or depression of inhibitory synapses are now beginning to be unraveled. At the presynaptic level, retrograde synaptic signaling was demonstrated to modulate GABA release, whereas postsynaptic forms of plasticity involve changes in the number/gating properties of GABAA receptors and/or shifts of chloride gradients. In addition, recent research indicates that GABAergic tonic inhibition can also be plastic, adding a further level of complexity to the control of the excitatory/inhibitory balance in the brain. The present Topic will focus on plasticity of GABAergic synapses, with special emphasis on the molecular mechanisms of plasticity induction and/or expression.

Book Description
Traumatic brain injury (TBI) is a significant public health problem. There are several advanced techniques available for the investigation of disease neurobiology, diagnosis, and treatment. This book covers many topics in the active TBI research field such as cumulative mild head injury review, brain changes, and risk factors, as well as post-concussion syndrome (PCS) definition, classification, and association with brain dysfunction. Brain changes, including blood flow, intracranial pressure, and neuroinflammation, the neurobiological basis of neuroprotective activation, as well as correlation with PCS, including sleep, are illustrated further. Furthermore, multiple biomarkers, including S-100?, UCH-L1, and GFAP for blood-brain barrier breakdown and neuronal injury, are reviewed thoroughly. Lastly, well-evaluated neuroprotective agents, hypothermia as a neuroprotective effect in TBI, and effects investigation, as well as sedation in TBI as a neurocritical and therapeutic strategy with different assessments, are reported. This book introduces readers to a number of perspectives, including TBI disease pathophysiology and post-concussion syndrome classification, associated brain changes, imaging diagnosis, and several useful biomarkers with high sensitivities, as well as multiple therapeutic strategies. Various advanced technical developments, upfront neuroimaging, and clinical data are presented together with comprehensive, up-to-date, and interesting examples.

Book Description
Common wealth dividends are universal cash payments funded by fees on the private use of common resources like land, minerals, and the atmosphere as a carbon sink. Thomas Paine’s 1797 pamphlet Agrarian Justice and Alaska’s Permanent Fund Dividend are staples in the literature on Basic Income, but there is much more to common wealth dividends beyond these highlights, and common wealth dividends have a distinctive ethical justification and distinctive policy implications that merit discussion. This monograph, the most comprehensive study of common wealth dividends to date, will be of interest to students, teachers, and advocates of Basic Income and those in the field of environmental studies, including sustainable development, natural resource management, and climate policy.

Book Description
Development of new imaging technologies in recent years has transformed neuroscience in profound ways. Following on the heels of the revolution based on the Green Fluorescent Protein, refined genetically-encoded fluorescent reporters and genetic targeting strategies now enable optical recording of synaptic transmission in defined neuronal populations at speeds approaching the enviable temporal resolution of electrophysiology. Super-resolution light microscopy permits observation of synapses and their molecular machinery at sub-diffraction resolution. At the ultrastructural level, automated forms of electron microscopy, improvements in specimen fixation methods, and recent efforts to correlate data from light and electron micrographs now make the reconstruction of functional neural circuits a reality. Finally, the use of optogenetic actuators, such as channelrhodopsins, allows precise temporal and spatial manipulation of neuronal activity and is revealing profound insights into the organization of neural circuits and their roles in behavior. This research topic highlights recent advances in both light and electron microscopy, with a specific focus on approaches that combine innovations from several different fields to obtain novel information about synapse structure and function. We are confident that this collection of articles - three original research papers, six reviews, one methods paper and one perspective article - will enable neuroscientists to achieve the next generation of experiments aimed at cracking the neural code.
