Описание:

The definitive guide to treating neurologic and psychiatric disorders with drugs and other approaches

Doody's Core Titles for 2021!

Fully updated with the latest research and drugs, Nestler, Hyman, & Malenka's Molecular Neuropharmacology, Fourth Edition, is the leading guide to molecular neuroscience. Providing an in-depth look at the neuropharmacological fundamentals of the nervous system, it delivers the knowledge and insight you need to master the pathophysiology of neurologic and psychiatric disorders.

Complete with tables, diagrams, and figures clearly illustrating the intricacies of neurochemistry and molecular neuroscience, this peerless guide reviews the effects of drug action (organized by drug category) to enhance your understanding of major disease mechanisms, and it explains the pathophysiology and neuropharmacology of all major neurologic and psychiatric disorders. Concise overviews of the effects of drugs and other treatment approaches are presented in a way that boosts your understanding and retention of critical concepts.

Nestler, Hyman, & Malenka's Molecular Neuropharmacology provides a deep dive into:

• General principles of neurophar¬macology
• Nervous system function
• Drugs that act on neuronal and glial function
• Major neurotrans¬mitter systems in the brain and spinal cord
• Atypical neurotransmitters, including peptides, growth factors, and cytokines
• Major brain and spinal cord systems at the molecular, cellular, and circuit levels in health and disease

Описание: This volume contains the proceedings of the NATO Advanced Research Workshop on "Atomic and Molecular Wires". It was sponsored by the Ministry of Scientific Affairs Division special program on Nanoscale Science with the support of the CNRS and the Max Planck Institute. Scientists working or interested in the properties of wires at a subnanoscale were brought together in Les Houches (France) from 6 to 10 May 1996. Subnanoscale wires can be fabricated either by surface physicists (atomic wires) or by synthetic chemists (molecular wires). Both communities present their foremost advances using, for example, STM to assemble atomic lines atom for atom, to fabricate a mask for such a line or using the wide range of chemical synthesis techniques to obtain long, rigid and conjugated oligomers. Interconnecting such tiny wires to sources (voltage, current) continues to demand a great technological effort. But nanolithography associated with microfabrication or STM are now clearly identified paths for measuring the electrical resistance of an atomic or a molecular wire. The first measurements have been reported on Xe, benzene, C ' di(phenylene-ethynylene) showing 2 60 the need for a deeper understanding of transport phenomena through subnanowires. Such transport phenomena like tunnel (off-resonance) transport and Coulomb blockade have been discussed by theorists with an emphasis on the exponential decrease of the tunnel current with the wire length versus the ballistic regime of transport.
