The basal ganglia are involved in complex brain functions, from voluntary movement control to learning and reward processing, and they are implicated in numerous neurological and psychiatric disorders. Information from the cerebral cortex and thalamus is conveyed to basal ganglia nuclei via glutamate release, while dopamine from the midbrain is rel

The NMDA receptor plays a critical role in the development of the central nervous system and in adult neuroplasticity, learning, and memory. Therefore, it is not surprising that this receptor has been widely studied. However, despite the importance of rhythms for the sustenance of life, this aspect of NMDAR function remains poorly studied. Written

New research suggests it is highly probable that DOPA, in addition to being a precursor to dopamine, functions by itself as a neurotramsmitter and/or neuromodulator. Neurobiology of DOPA as a Neurotransmitter integrates background information about DOPA as an inert amino acid precursor of dopamine with the evidence showing that DOPA fulfills several criteria of neurotransmitters. Providing easy access to, and complete understanding of, the latest research on the subject, the book makes the case that DOPA meets many of the criteria of neurotransmitters and includes anti-evidence in some instances. The book begins with a historical review of current knowledge of DOPA. It characterizes DOPA as a prominent example showing transmutation from an inert substance to a gold drug in Parkinson's disease and further to a neurotransmitter in its own right. The next chapters cover the essential criteria of a neurotransmitter such as synthesis, existence, and competitive antagonism. The book describes metabolism composed of catecholamine synthesis and degradation products related to neuron death, physiological release of DOPA in the lower brainstem, striatum, and nucleus accumbens, and physiological or pharmacological responses involved in baroreflex neurotransmission and related to behavioral science including interactions with catecholamines, acetylcholine, glutamate, and GABA. The book explores recognition sites, transport sites, and therapeutic role and mechanisms for neuron death related to adverse influence in the treatment of Parkinson's Disease. Edited by experts in the field, the breadth and depth of information contained in this book is confirmed by a quick scan of the chapter authors. They summarize the issues surrounding DOPA neurotoxicity and explore the link between experimental studies and clinical relevance.

Fundamental biochemical studies of basic brain metabolism focusing on the neuroactive amino acids glutamate and GABA combined with the seminal observation that one of the key enzymes, glutamine synthetase is localized in astroglial cells but not in neurons resulted in the formulation of the term “The Glutamate-Glutamine Cycle.” In this cycle glutamate released from neurons is taken up by surrounding astrocytes, amidated by the action of glutamine synthetase to glutamine which can be transferred back to the neurons. The conversion of glutamate to glutamine is like a stealth technology, hiding the glutamate molecule which would be highly toxic to neurons due to its excitotoxic action. This series of reactions require the concerted and precise interaction of a number of enzymes and plasma membrane transporters, and this volume provides in-depth descriptions of these processes. Obviously such a series of complicated reactions may well be prone to malfunction and therefore neurological diseases are likely to be associated with such malfunction of the enzymes and transporters involved in the cycle. These aspects are also discussed in several chapters of the book. A number of leading experts in neuroscience including intermediary metabolism, enzymology and transporter physiology have contributed to this book which provides comprehensive discussions of these different aspects of the functional importance of the glutamate-glutamine cycle coupling homeostasis of glutamatergic, excitatory neurotransmission to basic aspects of brain energy metabolism. This book will be of particular importance for students as well as professionals interested in these fundamental processes involved in brain function and dysfunction.

Identification of Neural Markers Accompanying Memory is a fresh and novel volume of memory study, providing up-to-date and comprehensive information for both students and researchers focused on the identification of neural markers accompanying memory. Contributions by experts in specific areas of memory study provide background on and definitions of memory, memory alterations, and the brain areas involved in memory and its related processes, such as consolidation, retrieval, forgetting, amnesia, and antiamnesiac effects. With coverage of the principal neurotransmitters related to memory, brain disorders presenting memory alterations, and available treatments—and with discussion of neural markers as new targets for the treatment of memory alterations—Identification of Neural Markers Accompanying Memory is a necessary and timely work for researchers in this growing field. Discusses the alterations of memory in diverse diseases Includes coverage from a basic introduction of memory investigation Reviews brain areas and neurotransmitters involved in memory Discusses behavioral models of memory Contains novel insights into the complexity of signaling and memory Includes the neuropharmacological and neurobiological bases of memory

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
