Chromatic light adaptation measured using functional magnetic resonance imaging.

Sensitivity changes, beginning at the first stages of visual transduction, permit neurons with modest dynamic range to respond to contrast variations across an enormous range of mean illumination. We have used functional magnetic resonance imaging (fMRI) ...

A large-scale simulation of the piriform cortex by a cell automaton-based network model.

An event-driven framework is used to construct a physiologically motivated large-scale model of the piriform cortex containing in the order of 10(5) neuron-like computing units. This approach is based on a hierarchically defined highly abstract neuron ...

Ability and task constraint determinants of complex task performance.

Previous research on basic information-processing tasks has suggested that there may be a dissociation between the underlying process determinants of task performance and associations with ability measures. This study investigates this dissociation in ...

Evaluation of a virtual endoscopy simulator for training in gastrointestinal endoscopy.

BACKGROUND AND STUDY AIMS: Skills in gastrointestinal endoscopy mainly depend on experience and practice. Training on endoscopy simulators may decrease the time needed to reach competency in endoscopy. The purpose of the study was to determine whether ...

Interaction and presence in the clinical relationship: virtual reality (VR) as communicative medium between patient and therapist.

The great potential offered by virtual reality (VR) to clinical psychologists derives prevalently from the central role, in psychotherapy, occupied by the imagination and by memory. These two elements, which are fundamental in our life, present absolute ...

Retinal flow is sufficient for steering during observer rotation.

How do people control locomotion while their eyes are simultaneously rotating? A previous study found that during simulated rotation, they can perceive a straight path of self-motion from the retinal flow pattern, despite conflicting extraretinal ...

A knowledge-based cone-beam x-ray CT algorithm for dynamic volumetric cardiac imaging.

With the introduction of spiral/helical multislice CT, medical x-ray CT began a transition into cone-beam geometry. The higher speed, thinner slice, and wider coverage with multislice/cone-beam CT indicate a great potential for dynamic volumetric ...

Virtual endodontics: three-dimensional tooth volume representations and their pulp cavity access.

The purpose of this study was the application of both digital three-dimensional image processing and virtual reality techniques in endodontics. Three-dimensional volume representations of 2 teeth from each tooth category, 16 teeth in total, have been ...

The importance of being light: aerodynamic forces and weight in ski jumping.

Many contemporary world class ski jumpers are alarmingly underweight and several cases of anorexia nervosa have come to light. Athletes strive for low body weight because it gives them a major competitive advantage. In order to stop this hazardous ...
