Book excerpt: Drugs acting through 5-HT (5-hydroxytryptamine, or serotonin) systems modulate memory and its alterations, but the mechanisms by which they do so are poorly understood. Agonists and antagonists for 5-HT receptors, as well as serotonin uptake inhibitors, present promnesic (memory-promoting) and/or anti-amnesic effects under different conditions, and 5-HT receptors are also associated with neural changes. The Role of 5-HT Systems on Memory and Dysfunctional Memory: Emergent Targets for Memory Formation and Memory Alterations reviews and summarizes the most recent research related to 5-HT drugs and the mechanisms by which they effect alterations in memory. This latest evidence is reviewed in the context of memory deficits related to brain disorders, such as post-traumatic stress disorder, schizophrenia, post-stroke cognitive dysfunctions, Parkinson’s disease, and infection-induced memory impairments. Written by an expert in the field of memory, The Role of 5-HT Systems on Memory and Dysfunctional Memory provides an introduction to the latest research on 5-HT receptors and their contributions to the physiological and pharmacological basis of memory. Examines and summarizes the recent advances in drugs that act through the 5-HT systems Reviews findings in the context of brain disorders that involve memory deficits Covers emergent targets for memory formation and memory alterations

Available in PDF, EPUB and Kindle. Book excerpt: The study of 5-hydroxytryptamine (5-HT) systems has benefited from the identification, classification and cloning of multiple 5-HT receptors (5-HT1 to 5-HT7). Increasing evidence suggests that 5-HT pathways, reuptake site/transporter complex and 5-HT receptors represent a strategic distribution for learning and memory. A key question still remaining is whether 5-HT markers (e.g., receptors) are directly or indirectly contributing to the physiological and pharmacological basis of memory and its pathogenesis or, rather, if they represent protective or adaptable mechanisms. Certainly, Alzheimer´s disease (AD) is a very complex neuropsychiatric disorder, where memory becomes progressively dysfunctional resulting in amnesia and dementia, whereas forgetting is a physiological phenomenon occurring all the time as adaptive mechanism. As dysfunctional memory occurs in several neuropsychiatric disorders, including schizophrenia, stroke, post-traumatic stress disorder. Hence, the aim of this call is collect recent and important findings related to information about serotonin and memory or 5-HT and learning or 5-HT and memory or serotonin and learning.

This book was released on 2009-12-30 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: Serotonin (5-hydroxytryptamine, often cited as 5-HT) is one of the major excitatory neurotransmitter, and the serotonergic system is one of the best studied and understood transmitter systems. It is crucially involved in the organization of virtually all behaviours and in the regulation of emotion and mood. Alterations in the serotonergic system, induced by e.g. learning or pathological processes, underlie behavioural plasticity and changes in mood, which can finally results in abnormal behaviour and psychiatric conditions. Not surprisingly, the serotonergic system and its functional components appear to be targets for a multitude of pharmacological treatments - examples of very successful drugs targeting the serotoninergic system include Prozac and Zoloft. The last decades of research have not only fundamentally expanded our view on serotonin but also revealed in much more detail an astonishing complexity of this system, which comprises a multitude of receptors and signalling pathways. A detailed view on its role in basal, but also complex, behaviours emerged, and, was presented in a number of single review articles. Although much is known now, the serotonergic system is still a fast growing field of research contributing to our present understanding of the brains function during normal and disturbed behaviour. This handbook aims towards a detailed and comprehensive overview over the many facets of behavioural serotonin research. As such, it will provide the most up to date and thorough reading concerning the serotonergic systems control of behaviour and mood in animals and humans. The goal is to create a systematic overview and first hand reference that can be used by students and scholars alike in the fields of genetics, anatomy, pharmacology, physiology, behavioural neuroscience, pathology, and psychiatry. The chapters in this book will be written by leading scientists in this field. Most of them have already written excellent reviews in their field of expertise. The book is divided in 4 sections. After an historical introduction, illustrating the growth of ideas about serotonin function in behaviour of the last forty years, section A will focus on the functional anatomy of the serotonergic system. Section B provides a review of the neurophysiology of the serotonergic system and its single components. In section C the involvement of serotonin in behavioural organization will be discussed in great detail, while section D deals with the role of serotonin in behavioural pathologies and psychiatric disorders. The first handbook broadly discussing the behavioral neurobiology of the serotonorgic transmitter system Co-edited by one of the pioneers and opinion leaders of the past decades, Barry Jacobs (Princeton), with an international list (10 countries) of highly regarded contributors providing over 50 chapters, and including the leaders in the field in number of articles and citations: K.

Book excerpt: Recent research into the anatomy and pathophysiology of the blood-brain and blood-spinal cord barriers suggests that a breakdown in these barriers can result in several diseases affecting the central nervous system (CNS). This book presents new findings in the area of blood-brain barrier research that suggest barriers play important roles in health and disease conditions. It also discusses the development of new drugs that can modulate the barrier function in the CNS and may provide new approaches to treating neurological diseases such as Alzheimer's disease and other motor neuron diseases, as well as spinal cord trauma. Key Features * Presents the recent progress made in the research on the blood-brain and spinal cord barrier * Contains numerous illustrations of light and electron micrographs * Includes Foreword written by two eminent researchers in the field, Milton Brightman and Jorge Cervos-Navarro

This book was released on 2009 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Serotonin (5-hydroxytryptamine, 5-HT) is thought to be important during brain development and is one of the first neurotransmitters to appear. It appears to act as a neurotrophic factor supporting the growth and maturation of both serotonergic and non-serotonergic cells during the pre and early postnatal periods prior to its role as a neurotransmitter. Disruption of 5-HT functioning during human development is thought to be associated with autism and schizophrenia. Early developmental exposure to stress or drugs of abuse disrupt 5-HT development and produces altered cognitive ability. To better understand the relationship between the developing serotonergic system and long-term cognitive function we employed the use of a genetic model in which 5-HT levels are depleted ~80% throughout life and the use of a model of 3,4-methylenedioxymethamphetamine (MDMA) exposure in which administration from postnatal day (P)11-20 is used; a period analogous to the second half of human gestation. Pet-1 is a transcription factor that is restricted in the brain to 5-HT neurons and has been shown to be important for their development and function. A loss of Pet-1 results in an 80% reduction of the number of 5-HT neurons as well as 5-HT tissue content. Pet-1 knockouts were tested as adults in both the Cincinnati and Morris water mazes that assess path integration and spatial learning, respectively. A reduction in cognitive ability was not observed in Pet-1 knockout mice, although they displayed decreased locomotor activity, increased marble burying, and increased startle reactivity. To better assess the role 5-HT plays during development for circuits involved in memory formation, we used a model of MDMA exposure that has previously been reported to produce protracted path integration and spatial learning deficits that last late into adulthood. In adults, MDMA produces an initial release of 5-HT followed by dramatic depletions, and these depletions can last for weeks. It was previously shown that neonatal MDMA administration on P11, the first day of the exposure period known to result in memory impairment (P11-20), also produced significant depletions in 5-HT. We further characterized the degree of 5-HT depletion that was experienced by rats exposed to P11 MDMA exposure and compared this to 5-HT reductions induced by other substituted amphetamines as well as determining the length and degree of depletion following P11-20 MDMA exposure. Substantial 5-HT depletions existed during all ten days of MDMA exposure, however, these depletions were not observed on P30. Citalopram (CIT), a highly selective SSRI, was used in combination with P11-20 MDMA exposure to attenuate the 5-HT depletions. Thereafter, cognitive ability was assessed in MDMA-treated animals with attenuated 5-HT depletions. The combination of CIT and MDMA did not improve learning ability; however CIT treatment alone produced deficits in path integration learning. These data suggest that 5-HT alterations during vulnerable critical periods can affect later cognitive ability, and they suggest that depletions in 5-HT alone may not account for cognitive dysfunction in neonatal rats treated with MDMA. Examination of specific 5-HT receptors is likely the next step to understand the mechanism involved in 5-HT disruption during development and later cognitive ability.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on associative memory cells and their working principles, which can be applied to associative memories and memory-relevant cognitions. Providing comprehensive diagrams, it presents the author's personal perspectives on pathology and therapeutic strategies for memory deficits in patients suffering from neurological diseases and psychiatric disorders. Associative learning is a common approach to acquire multiple associated signals, including knowledge, experiences and skills from natural environments or social interaction. The identification of the cellular and molecular mechanisms underlying associative memory is important in furthering our understanding of the principles of memory formation and memory-relevant behaviors as well as in developing therapeutic strategies that enhance memory capacity in healthy individuals and improve memory deficit in patients suffering from neurological disease and psychiatric disorders. Although a series of hypotheses about neural substrates for associative memory has been proposed, numerous questions still need to be addressed, especially the basic units and their working principle in engrams and circuits specific for various memory patterns. This book summarizes the developments concerning associative memory cells reported in current and past literature, providing a valuable overview of the field for neuroscientists, psychologists and students.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the neurobiological basis of psychiatric disease has accelerated in the past five years. The fourth edition of Neurobiology of Mental Illness has been completely revamped given these advances and discoveries on the neurobiologic foundations of psychiatry. Like its predecessors the book begins with an overview of the basic science. The emerging technologies in Section 2 have been extensively redone to match the progress in the field including new chapters on the applications of stem cells, optogenetics, and image guided stimulation to our understanding and treatment of psychiatric disorders. Sections' 3 through 8 pertain to the major psychiatric syndromes-the psychoses, mood disorders, anxiety disorders, substance use disorders, dementias, and disorders of childhood-onset. Each of these sections includes our knowledge of their etiology, pathophysiology, and treatment. The final section discusses special topic areas including the neurobiology of sleep, resilience, social attachment, aggression, personality disorders and eating disorders. In all, there are 32 new chapters in this volume including unique insights on DSM-5, the Research Domain Criteria (RDoC) from NIMH, and a perspective on the continuing challenges of diagnosis given what we know of the brain and the mechanisms pertaining to mental illness. This book provides information from numerous levels of analysis including molecular biology and genetics, cellular physiology, neuroanatomy, neuropharmacology, epidemiology, and behavior. In doing so it translates information from the basic laboratory to the clinical laboratory and finally to clinical treatment. No other book distills the basic science and underpinnings of mental disorders and explains the clinical significance to the scope and breadth of this classic text. The result is an excellent and cutting-edge resource for psychiatric residents, psychiatric researchers and doctoral students in neurochemistry and the neurosciences.
