Recognizing a well-known melody (e.g., one's national anthem) is not an all-or-none process. Instead, recognition develops progressively while the melody unfolds over time. To examine which factors govern the time course of this recognition process, the gating paradigm, initially designed to study auditory word recognition, was adapted to music. Musicians and nonmusicians were presented with se...

We propose and demonstrate a new technique for realizing wavelength tuning that promises rapid response over a wide optical bandwidth. Wavelength tuning is obtained by varying the delay of the RF pulse that time-gates a linearly chirped Super Continuum (SC). Preliminary experiments demonstrating static tuning range of 90nm are reported.

We demonstrate a method for time gating the standard heralded cw spontaneous parametric downconverted single-photon source by using pulsed pumping of an optical parametric oscillator below threshold. The narrow bandwidth, high purity, high spectral brightness, and pseudodeterministic character make the source highly suitable for light-atom interfaces with atomic memories.

Medial prefrontal cortex is a crucial region involved in inhibitory processes. Damage to the medial prefrontal cortex can lead to loss of normal inhibitory control over motor, sensory, emotional and cognitive functions. The goal of the present study was to examine the basic properties of inhibitory gating in this brain region in rats. Inhibitory gating has recently been proposed as a neurophysi...

Power reduction in dynamic circuits became an important factor today. In this thesis, we designs an ALU using the popular power reduction techniques named clock gating and precomputation based sequential logic optimization for low power . It reduces the power consumption by reducing the dynamic switching power. Power reduction deals with synthesis, design at circuit level and placement and rout...

Real-time systems are frequently used as an experimental tool, whereby simulated models interact in real time with neurophysiological experiments. The most demanding of these techniques is known as the dynamic clamp, where simulated ion channel conductances are artificially injected into a neuron via intracellular electrodes for measurement and stimulation. Methodologies for implementing the nu...

Precise localization of mobile tumor positions in real time is critical to the success of gated radiotherapy. Tumor positions are usually derived from either internal or external surrogates. Fluoroscopic gating based on internal surrogates, such as implanted fiducial markers, is accurate however requiring a large amount of imaging dose. Gating based on external surrogates, such as patient abdom...

CONTEXT The auditory sensory gating deficit has been considered a leading endophenotype in schizophrenia. However, the commonly used index of sensory gating, P50, has low heritability in families of people with schizophrenia, raising questions about its utility in genetic studies. We hypothesized that the sensory gating deficit may occur in a specific neuronal oscillatory frequency that reflect...

435 C o m m e n t a r y Decades ago as a beginning graduate student, one of us (K.L.M.) was studying short-term synaptic plasticity at the neuromuscular synapse. The responses were generally consistent from day to day, but there was some variability. At that time, K.L.M. naively thought that if it were possible to directly study the macromolecular building blocks underlying neuromuscular transm...
