Lateralized Temporal Integration Properties of the Mouse Auditory Cortex
… is believed to have an effect on the temporal fidelity, the ability to follow a modulating signal, and the recurrent activity, sustained activity following stimulus offset, at the level of individual neurons and at the level of the circuits. Preliminary evidence from this lab has shown …

Temporal integration in the neural substrate for brain stimulation reward : duration neglect and the peak-and-end model
… two competing theories of how organisms evaluate temporally-extended appetitive experiences. The "peak" model states that the most rewarding moment of the experience is recorded into memory, while the "peak-and-end" model asserts that remembered reward value is an averaging of both the "peak" …

Multi-source human identification
… this system, classifier combination and the integration of classifer outputs over sequences of data points were studied in detail. The method of classifier combination used relies on weighing classifiers based on the Maximum Likelihood estimation of class probabilities. The integration of …

Constructing multiple objects across space and time
… a single representation of an object or event. Temporal integration, the process of combining information over time is one important prerequisite for it. Likewise, multisensory integration, the process of combining information from different sensory modalities to generate a coherent percept is …

Mechanisms of Gradient Tracking During Yeast Mating
… time to allow noise filtering. The mechanism of temporal integration is unknown. We used the mating response of the budding yeast, <italic>Saccharomyces cerevisiae</italic>, as a model to study eukaryotic gradient tracking. </p><p>During mating, yeast cells polarize and grow up a gradient of …

Boundary integral/spectral element solution of the Navier-Stokes equations
… equation. A semi-implicit formulation of the temporal integration rendered a linear spatial problem at sequential time increments. For low to moderate Reynolds number flows, time stepping tests of the complete method provided stable Navier-Stokes simulations for simple model flows in an …

Analysis of metal matrix composite structures using a micromechanical constitutive theory
… aspects of the numerical solution, such as the temporal integration of the inelastic strains and the spatial integration of bending moments are addressed. Numerical results are presented which illustrate the nonlinear response of metal matrix composites subjected to extensional and bending …

Auditory Temporal Processing in Children with Specific Language Impairment Compared to Same-Age Controls
… (SLI) originates from immature auditory temporal integration (ATI), but results are inconsistent. We compared electroencephalographic data from 25 children with SLI aged 6-11 years to 25 typically developing peers. Participants’ neural responses to a 50ms tone presented alone were …

A preliminary study on the effect of selective serotonin reuptake inhibitors on peripheral and lower brainstem auditory processing.
… otoacoustic emissions, masking level difference, temporal integration, amplitude resolution, and Beck Depression Inventory-II (BDI-II) scores. Results indicated that there was a significant difference in the amplitude resolution of the unmedicated group when compared to the medicated and the …

Error analysis of higher order time-domain finite element methods for the one-dimensional Maxwell's equations
… method has been extended for higher order temporal accuracy using several schemes. While common in computational fluid dynamics, less research has been conducted with these methods for computational electromagnetics. A stabilized finite element method utilizing the Streamline/Upwind …

Image -Percept Integration as a Means to Construct Visual Representations Over Time in Static and Dynamic Displays
… interaction of memory and perception. Using a temporal integration paradigm, subjects had to integrate information from temporally separated visual presentations into a single representation in order to accomplish a behavioral task. The primary focus of the experiments presented here was to …

Recurrent neural networks in cognitive and vision neuroscience
… neural networks on tasks requiring long-term temporal dependencies, which are critical components of cognitive functions such as working memory and decision-making. By introducing specialized skip-connections to promote the emergence of task-relevant dynamics, we enable these networks to …

Mathematical Models of the Representation of Faces in Humans
… over time? In chapter 2 a simple model of temporal integration is set forth, based on the statistical technique of exponential smoothing. In chapter 3 results of experiments testing this model are presented, demonstrating the model to be inadequate in certain respects. In particular a …
