Control of kinetic properties of GluR2 flop AMPA-type channels: impact of R/G nuclear editing.

The GluR2 flop subunit of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-type glutamate receptors greatly determines calcium permeability and kinetic properties of heteromeric AMPA subunit assemblies. Post-transcriptional editing of this ...

Virtual reality and simulation: training the future emergency physician.

The traditional system of clinical education in emergency medicine relies on practicing diagnostic, therapeutic, and procedural skills on live patients. The ethical, financial, and practical weaknesses of this system are well recognized, but the ...

Neuroengineering modeling of single neuron and neural interface.

The single neuron has attracted widespread attention as an elementary unit for understanding the electrophysiological mechanisms of nervous systems and for exploring the functions of biological neural networks. Over the past decades, much modeling work ...

Color opponent neurons in V1: a review and model reconciling results from imaging and single-unit recording.

The signals in visual cortex that ultimately give rise to color perception remain poorly understood. Controversy has particularly surrounded one aspect of colors encoding in the visual system-opponent processing in primary visual cortex. Early ...

Exploring the boundaries of plausibility: empirical study of a key problem in the design of computer-based clinical simulations.

All clinical simulation designers face the problem of identifying the plausible diagnostic and management options to include in their simulation models. This study explores the number of plausible diagnoses that exist for a given case, and how many ...

Modeling head tracking of visual targets.

Control of the head involves somatosensory, vestibular, and visual feedback. The dynamics of these three feedback systems must be identified in order to gain a greater understanding of the head control system. We have completed one step in the ...

Human vagal heart rate responses in warned reaction time tasks: a cross-validation with simulated vagus-sino-atrial node interactions.

This study examines the hypothesis that human heart rate responses in reaction time (RT) tasks are mediated by changes in vagal nerve activity. Experimental results were compared to simulated heart rate (HR) responses. An animal model of vagus-cardiac ...

Detecting and evaluating the impact of multidimensionality using item fit statistics and principal component analysis of residuals.

The purpose of this research is twofold. First is to extend the work of Smith (1992, 1996) and Smith and Miao (1991, 1994) in comparing item fit statistics and principal component analysis as tools for assessing the unidimensionality requirement of Rasch ...

Agent-based computational economics: growing economies from the bottom up.

Agent-based computational economics (ACE) is the computational study of economies modeled as evolving systems of autonomous interacting agents. Thus, ACE is a specialization of economics of the basic complex adaptive systems paradigm. This study outlines ...

Fast temporal dynamics of visual cue integration.

The integration of information from different sensors, cues, or modalities lies at the very heart of perception. We are studying adaptive phenomena in visual cue integration. To this end, we have designed a visual tracking task, where subjects track a ...
