The Role Of 5 Ht Systems On Memory And Dysfunctional Memory

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

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.

Annotation The serotonin 5-HT6 receptor represents a novel pharmacological target whose impact on physiopathology of CNS functions remains undetermined. Some receptor antagonists have been synthesized and they show a modulatory role in learning and memory processes and food intake.

The serotonin 5-HT6 receptor represents a novel pharmacological target whose impact on physiopathology of CNS functions remains undetermined. Some receptor antagonists have been synthesized, and they show a modulatory role in learning and memory processes and food intake. The pharmacology of 5-HT6 receptor agonists is still under evaluation. However, both 5-HT6 antagonists and agonists seem to exert potential antidepressant activity. Recently, a second messenger system has been discovered. 5-HT6 receptor function is becoming more and more intriguing. Thus, the aim of the present book is to try to clarify the pharmacology of 5-HT6 receptors. Written by expert researchers Covers all published literature to date in the field of 5-HT6 receptors

The premise of neuroplasticity on enhancing cognitive functioning among healthy as well as cognitively impaired individuals across the lifespan, and the potential of harnessing these processes to prevent cognitive decline attract substantial scientific and public interest. Indeed, the systematic evidence base for cognitive training, video games, physical exercise and other forms of brain stimulation such as entrain brain activity is growing rapidly. This Research Topic (RT) focused on recent research conducted in the field of cognitive and brain plasticity induced by physical activity, different types of cognitive training, including computerized interventions, learning therapy, video games, and combined intervention approaches as well as other forms of brain stimulation that target brain activity, including electroencephalography and neurofeedback. It contains 49 contributions to the topic, including Original Research articles (37), Clinical Trials (2), Reviews (5), Mini Reviews (2), Hypothesis and Theory (1), and Corrections (2).

A number of developments spanning a multitude of techniques makes this an exciting time for research in serotonin receptors. A comprehensive review of the subject from a multidisciplinary perspective, Serotonin Receptors in Neurobiology is among the first books to include information on serotonin receptor knockout studies. With contributions from leading experts in their fields, the book explores serotonin receptors from a broad-based, multidisciplinary approach. The approaches described vary from molecular biological techniques to fluorescence microscopy and imaging, to genetic manipulation in animal models, providing a wide range of tools to study serotonergic phenomena. While each of these approaches has its own advantages and limitations, the synthesis of information and knowledge achieved from studies using multiple approaches will result in a comprehensive understanding of the underlying complex phenomena involved in serotonergic signaling and its implications in health and disease. The book provides an overall understanding of these receptors based on currently used methodologies and techniques. It describes specific experimental procedures that will be of use to researchers interested in addressing similar problems involving other G-protein-coupled receptor signaling systems.
