Walking, looking to the side, and taking curved paths.

In two experiments, viewers judged heading from displays simulating locomotion through tree-filled environments, with gaze off to the side. They marked their heading with a mouse-controlled probe at three different depths. When simulated eye or head ...

Task-induced fatigue states and simulated driving performance.

States of fatigue are implicated in driver impairment and motor vehicle accidents. This article reports two studies investigating two possible mechanisms for performance impairment: (1) loss of attentional resources; and (2) active regulation of matching ...

The formation of structurally relevant units in artificial grammar learning.

A total of 78 adult participants were asked to read a sample of strings generated by a finite state grammar and, immediately after reading each string, to mark the natural segmentation positions with a slash bar. They repeated the same task after a phase ...

Can virtual reality be used to measure and train surgical skills?

The quantitative literature on the use of virtual environments to measure and train a variety of surgical skills is critically reviewed. We selected works from the years 1995-2000. Theoretical perspectives, such as those of Saltzman (1979), Bernstein ...

Virtual reality surgical simulation for lower urinary tract endoscopy and procedures.

BACKGROUND AND PURPOSE: To provide a realistic experience of lower urinary tract endoscopic procedures, we have developed and continue to expand a computer-based surgical simulator that incorporates a surgical tool interface with anatomic detail and ...

The use of a neural network system in the identification of motor unit characteristics from surface detected action potentials: a simulation study.

The surface detected motor unit action potential (MUAP) morphology depends on many physiological and anatomical characteristics of the contracting muscle that are not directly accessible to measurement. In this paper, a neural network based approach is ...

Large-scale neural model for visual attention: integration of experimental single-cell and fMRI data.

A computational neuroscience framework is proposed to better understand the role and the neuronal correlate of spatial attention modulation in visual perception. The model consists of several interconnected modules that can be related to the different ...

A decision support simulation model for the management of an elective surgery waiting system.

This paper describes the design of a simulation model to provide decision support for the scheduling of patients waiting for elective surgery in the public hospital system. Patients nominated for surgery by doctors are categorised by urgency and type of ...

Simulation and the future of military medicine.

The U.S. military currently faces serious difficulties in training medical personnel in peacetime for the tasks of war. The military beneficiary population comprises fit young service men and women, their dependents, and retirees. Their peacetime care, ...

Dissociating ocular dominance column development and ocular dominance plasticity: a neurotrophic model.

Recent experimental data indicate that both neurotrophic factors (NTFs) and intracortical inhibitory circuitry are implicated in the development and plasticity of ocular dominance columns. We extend a neurotrophic model of developmental synaptic ...
