Plasticity of GABAergic Synapses
Learning and memory are believed to depend on plastic changes of neuronal circuits due to activity-dependent potentiation or depression of specific synapses. During the last two decades, plasticity of brain circuits was hypothesized to mainly rely on the flexibility of glutamatergic excitatory synapses, whereas inhibitory synapses were assumed relatively invariant, to ensure stable and reliable control of the neuronal network. As a consequence, while considerable efforts were made to clarify the main mechanisms underlying plasticity at excitatory synapses, the study of the cellular/molecular mechanisms of inhibitory plasticity has received much less attention. Nevertheless, an increasing bod...
Novel Approaches for Single Molecule Activation and Detection
How can we obtain tools able to process and exchange information at the molecular scale? In order to do this, it is necessary to activate and detect single molecules under controlled conditions. This book focuses on the generation of biologically-inspired molecular devices. These devices are based on the developments of new photonic tools able to activate and stimulate single molecule machines. Additionally, new light sensitive molecules can be selectively activated by photonic tools. These technological innovations will provide a way to control activation of single light-sensitive molecules, allowing the investigation of molecular computation in a biological environment.
Building up the inhibitory synapse
Fast inhibitory transmission exerts a powerful control on neuronal excitability and network oscillations thought to be associated with high cognitive functions. An alteration of inhibitory signaling is associated with major neurological and psychiatric disorders including epilepsy. Once released from presynaptic nerve terminals, GABA and glycine cross the synaptic cleft and bind to postsynaptic receptors localized in precise apposition to presynaptic release sites. The functional organization of inhibitory synapses consists in a dynamic process which relies on a number of highly specialized proteins that ensure the correct targeting, clustering, stabilization and subsequent fate of synaptic ...
Minding Glial Cells in the Novel Understandings of Mental Illness
Traditionally, abnormalities of neurons and neuronal networks including synaptic abnormalities and disturbance of neurotransmitters have dominantly been believed to be the main causes of psychiatric disorders. Recent cellular neuroscience has revealed various unknown roles of glial cells such as astrocytes, oligodendrocytes and microglia. These glial cells have proved to continuously contact with neurons /synapses, and have been shown to play important roles in brain development, homeostasis and various brain functions. Beyond the classic neuronal doctrine, accumulating evidence has suggested that abnormalities and disturbances of neuron-glia crosstalk may induce psychiatric disorders, while...
Inorganic Nanoparticles
Among the various nanomaterials, inorganic nanoparticles are extremely important in modern technologies. They can be easily and cheaply synthesized and mass produced, and for this reason, they can also be more readily integrated into applications. Inorganic Nanoparticles: Synthesis, Applications, and Perspectives presents an overview of these special materials and explores the myriad ways in which they are used. It addresses a wide range of topics, including: Application of nanoparticles in magnetic storage media Use of metal and oxide nanoparticles to improve performance of oxide thin films as conducting media in commercial gas and vapor sensors Advances in semiconductors for light-emitting...
Inhibitory Synaptic Plasticity
This volume will explore the most recent findings on cellular mechanisms of inhibitory plasticity and its functional role in shaping neuronal circuits, their rewiring in response to experience, drug addiction and in neuropathology. Inhibitory Synaptic Plasticity will be of particular interest to neuroscientists and neurophysiologists.
Per una ragione artificiale. In dialogo con Lorenzo d’Avack su Costituzione, ordine giuridico e biodiritto
La ricchezza dei saggi e delle testimonianze raccolte in questo volume documenta il contributo fondamentale che l’opera di Lorenzo d’Avack ha apportato agli studi sui temi della Costituzione, della bioetica e del biodiritto. Partecipano alla raccolta di scritti molte delle voci che si sono confrontate con d’Avack durante la sua lunga, e tuttora in corso, esperienza al Comitato Nazionale per la Bioetica. Non solo filosofi del diritto, giuristi provenienti da diverse discipline, bioeticisti e umanisti con diverse sensibilità, ma anche medici, clinici e esperti di neuroscienze. Il volume offre, pertanto, un compendio dei temi e dei problemi che la bioetica e il biodiritto hanno affrontat...
