Available in PDF, EPUB and Kindle. Book excerpt: High-order executive tasks involve the interplay between frontal cortex and other cortical and subcortical brain regions. In particular, the frontal cortex, striatum and thalamus interact via parallel fronto-striatal "loops" that are crucial for the executive control of behavior. In all of these brain regions, neuromodulatory inputs (e.g. serotonergic, dopaminergic, cholinergic, adrenergic, and peptidergic afferents) regulate neuronal activity and synaptic transmission to optimize circuit performance for specific cognitive demands. Indeed, dysregulation of neuromodulatory input to fronto-striatal circuits is implicated in a number of neuropsychiatric disorders, such as schizophrenia, depression, and Parkinson's disease. However, despite decades of intense investigation, how neuromodulators influence the activity of fronto-striatal circuits to generate the precise activity patterns required for sophisticated cognitive tasks remains unknown. In part, this reflects the complexity of the cellular microcircuits in these brain regions (i.e. heterogeneity of neuron subtypes and connectivity), cell-type specific expression patterns for the numerous receptor subtypes mediating neuromodulatory signals, and the potential interaction of multiple signaling cascades in individual neurons. This Research Topic includes 10 original research articles and seven review articles addressing the role of neuromodulation in executive function at multiple levels of analysis, ranging from the activity of single voltage-dependent ion channels to computational models of network interactions in cortex-striatum-thalamus systems.

This book was released on 2020-06-04 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Movement is the basis for many forms of behaviors, and is tightly controlled by a hierarchical system containing cerebral cortex, basal ganglia, cerebellum, brainstem, and spinal cord. Each level of this hierarchy contributes to motor planning, motor initiation, motor execution, and motor coordination, respectively. However, they all receive continuous sensory inputs and generate accurate sensorimotor integrations that are necessary for both predictive and reflexive/servo controls of movements. The motor system contains various types of neurons with different morphological, neurochemical and electrophysiological properties, which are significantly dependent on many intracellular signaling molecules. Interestingly, these neurons are interconnected by intricate neuronal circuits for motor control, and even interacted with other non-motor systems to orchestrate somatic-nonsomatic integration. Furthermore, synaptic and neural plasticity endows motor system with amazing abilities for not only motor learning but also compensation and recovery from motor diseases, such as Parkinson’s disease, ataxias, motion sickness and amyotrophic lateral sclerosis, etc. Therefore, the motor system is of great importance for understanding information processing, integrative function, and neural plasticity of the central nervous system. The aim of this Research Topic is to discuss the latest advances in our understanding of motor system, motor control, motor learning and motor diseases from molecular, cellular, synaptic, circuit, and behavioral levels, especially in an integrative perspective.

Download or read book Development and Engineering of Dopamine Neurons written by Jeroen Pasterkamp and published by Springer Science & Business Media. This book was released on 2009-12-16 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theneurotransmitter dopamine has just celebrated its 50thbirthday. The discovery of dopamine as a neuronal entity in the late 1950s and the notion that it serves in neurotransmission has been a milestone in the field of neuroscience research. This milestone marked the beginning of an era that explored the brain as an integrated collection of neuronal systems that one could distinguish on basis of neurotransm- ter identities, and importantly, in which one started to be able to pinpoint the seat of brain disease. The mesodiencephalic dopaminergic (mdDA) system, previously designated as midbraindopaminergic system, has received much attention since its discovery. The initial identification of dopamine as a neurotransmitter in the central nervous system (CNS) and its relevance to psychiatric and neurological disorders have stimulated a plethora of neurochemical, pharmacological and genetic studies into the function of dopamine neurons and theirprojections. In the last decade, studies on gene expression and development have further increased the knowledge of this neuronal population and have unmasked a new level of complexity. The start of the molecular dissection of the mdDA system has been marked by the cloning and characterization ofNurrl and Pitx3. These transcription factors were shown to have a critical function during mdDA development. These initial studies have been followed by the identification of many other proteins, which have a crucial function in the creation of a dopamine neuron permissive region, induction of precursors, induction of terminaldifferent- tion and finally maintenance of the mdDA neuronal pool.

Available in PDF, EPUB and Kindle. Book excerpt: "Description and discussion of the many aspects of Parkinson disease (PD) is dogged by the fact that PD is an ambiguous concept. What we call PD is an etiologically and clinically heterogeneous meta-syndrome overlapping a number of other disorders. Definitions, diagnostic criteria, and classification schema provide essential common vocabularies for communication among clinicians and researchers. Definitions, diagnostic criteria, and classification schemes for PD, however, are constructs imposed on variable and imperfectly understood disease biology. Difficulties with formulation of PD definitions, diagnostic criteria, and classification schemes include historical and contemporary use of competing definitions of PD, disease heterogeneity, the existence of disorders with overlapping clinical and pathological features, and ambiguous use of the terms disease and syndrome. For the purposes of exposition and discussion in this book, an inclusive, perhaps vague, definition of PD is employed:"

Available in PDF, EPUB and Kindle. Book excerpt: The genetic correlates of neuropsychiatric disorders are now known, but none have come close to explaining the great variety of human psychiatric illnesses. This volume, written by a neuropsychiatrist and an evolutionary biologist, offers a new paradigm for understanding these disorders. Proposing that neuronal pathways which underlie neuropsychiatric conditions mirror unique human capabilities, the authors iterate a new paradigm by which to understand human psychiatric illnesses. Human capabilities such as theory of mind, language, and complex social behaviors are explored through their histological, neuroanatomical and functional brain imaging correlates. The capacity for representation, the authors suggest, is central to the understanding of the human brain. Brain structures such as the frontal pole, temporal pole, and fronto-insular cortex are highly developed in humans and are associated with representation. Other brain regions, including the dorsal anterior cingulate cortex, auditory cortex, and hippocampus, are linked with directed effort while the ventral anterior cingulate cortex, orbital frontal cortex, and amygdala are related to emotional encoding. Both networks interact with representional regions and the dorsolateral prefrontal cortex. Conditions like schizophrenia may result, in part, from a failure of the networks associated with directed effort while bipolar disorders may arise from a failure of networks associated with emotional encoding. Similarly, autism may result from a failure of representational brain regions; frontotemporal dementia may be associated with failure of several discrete networks in later life. From this perspective, neuropsychiatric disorders are selective failures of brain networks involved in the integration of cognition, affect and perception. A better understanding of these brain networks will assist psychiatric and mental health researchers in the search for environmental factors and genetic correlates of disorders as well as aid in the development of more effective treatments for these diseases. This volume will be of interest to psychiatrists, neurologists, psychologists, biologists, and imaging scientists--anyone who has ever wondered what makes the human brain human.
Download or read book Decoding Neural Circuit Structure and Function written by Arzu Çelik and published by Springer. This book was released on 2017-07-24 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers representative examples from fly and mouse models to illustrate the ongoing success of the synergistic, state-of-the-art strategy, focusing on the ways it enhances our understanding of sensory processing. The authors focus on sensory systems (vision, olfaction), which are particularly powerful models for probing the development, connectivity, and function of neural circuits, to answer this question: How do individual nerve cells functionally cooperate to guide behavioral responses? Two genetically tractable species, mice and flies, together significantly further our understanding of these processes. Current efforts focus on integrating knowledge gained from three interrelated fields of research: (1) understanding how the fates of different cell types are specified during development, (2) revealing the synaptic connections between identified cell types (“connectomics”) using high-resolution three-dimensional circuit anatomy, and (3) causal testing of how iden tified circuit elements contribute to visual perception and behavior.
