The Effect of Different Forms of Synaptic Plasticity on Pattern Recognition in the Cerebellar Cortex [PDF]
, 2009 “The original publication is available at www.springerlink.com”. Copyright Springer.Many cerebellar learning theories assume that long-term depression (LTD) of synapses between parallel fibres (PFs) and Purkinje cells (PCs) provides the basis for pattern

Aging and Synaptic Plasticity: A Review [PDF]
Neural Plasticity, 2002 Aging affects all systems, but the brain seems to be particularly vulnerable to the action of negative, age‐dependent factors. A gradual loss of memory functions is one of the earliest and most widespread consequences of brain aging. The causes for such impairment are still unclear.

Advanced Functional Materials, EarlyView.A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Synaptic plasticity: Neighborhood influences [PDF]
Current Biology, 1997 Recent studies indicate that, when the strengths of specific synapses are modified by activity, changes in strengths also occur at neighboring synapses; this neighborhood influence has important implications for how synaptic modifications implement learning and memory.

Synaptic Plasticity in an Altered State [PDF]
Neuron, 2002 In this issue of Neuron, record from synaptically coupled pairs of CA3 neurons to closely examine the induction of synaptic depression at a small number of identified synapses. The authors provide convincing evidence that the activation history of a synapse determines both the ability of a synapse to depress and the mechanism of depression.

Tunable Tactile Synapses Enabled by Erasable Doping in Iongel‐Gated Nanotube Network Transistors
Advanced Functional Materials, EarlyView.Artificial tactile synaptic sensors are realized by an iongel‐gated single‐walled carbon nanotube (SWCNT) transistor with reversible doping characteristics. The device senses and memorizes tactile stimuli and exhibits gate bias‐dependent excitatory or inhibitory synaptic behavior.

Synaptic Plasticity and Nicotine Addiction [PDF]
Neuron, 2001 Nicotine, the main addictive component of tobacco, activates and desensitizes nicotinic acetylcholine receptors (nAChRs). In that way, nicotine alters normal nicotinic cholinergic functions. Among the myriad of psychopharmacological effects that underlie the addiction process, nicotine influences nAChR participation in synaptic plasticity.

Multielement Filament Memristor Enabling Multifunctional Neuromorphic Device
Advanced Functional Materials, EarlyView.A new type of memristor featuring a hybrid mechanism and multifunctional applications is introduced. The proposed single device combines the alloy metal filament with the oxygen vacancy filament to achieve both resistive and threshold switching with enhanced reliability, mimicking both biological synapses and nociceptors. This study shows that filament‐

Current Biology, 1999 Synaptic activity can induce neurons to synthesize proteins important for cognition and brain development. Recent results suggest this activity-induced protein synthesis is partially mediated by regulated translation within neuronal dendrites.

Carbon Nanotube 3D Integrated Circuits: From Design to Applications
Advanced Functional Materials, EarlyView.As Moore's law approaches its physical limits, carbon nanotube (CNT) 3D integrated circuits (ICs) emerge as a promising alternative due to the miniaturization, high mobility, and low power consumption. CNT 3D ICs in optoelectronics, memory, and monolithic ICs are reviewed while addressing challenges in fabrication, design, and integration.
