Changes in linear and nonlinear EEG measures as a function of task complexity: evidence for local and distant signal synchronization.

The purpose of the present study was threefold: First, to replicate previous findings of changes in local gamma band power as a function of the complexity of a visuo-semantic processing task, second, to extend these findings in tasks delivered in the ...

Computational modeling of foveal target detection.

This paper presents the VDM2000, a computational model of target detection designed for use in military developmental test and evaluation settings. The model integrates research results from the fields of early vision, object recognition, and ...

A computational model as neurodecoder based on synchronous oscillation in the visual cortex.

Based on synchronized responses of neuronal populations in the visual cortex to external stimuli, we proposed a computational model consisting primarily of a neuronal phase-locked loop (NPLL) and multiscaled operator. The former reveals the function of ...

The effects of enhanced visual feedback on human synchronization.

The execution of actions not only reposes on the spatial and temporal organization of the movements as such but also on their appropriate imbedding into the environmental spatio-temporal constraints. Actually, performance outcome appears to be strongly ...

Visual field anisotropy revealed by perceptual filling-in.

Four experiments were performed to investigate how the time required for perceptual filling-in varies with the position of the target in the visual field. Conventional studies have revealed that filling-in is facilitated by a target with greater ...

Faces and objects in macaque cerebral cortex.

How are different object categories organized by the visual system? Current evidence indicates that monkeys and humans process object categories in fundamentally different ways. Functional magnetic resonance imaging (fMRI) studies suggest that humans ...

When is early visual cortex activated during visual mental imagery?

Although many neuroimaging studies of visual mental imagery have revealed activation in early visual cortex (Areas 17 or 18), many others have not. The authors review this literature and compare how well 3 models explain the disparate results. Each study ...

A review of evidence-based traffic engineering measures designed to reduce pedestrian-motor vehicle crashes.

We provide a brief critical review and assessment of engineering modifications to the built environment that can reduce the risk of pedestrian injuries. In our review, we used the Transportation Research Information Services database to conduct a search ...

Visual feature integration theory: past, present, and future.

Visual feature integration theory was one of the most influential theories of visual information processing in the last quarter of the 20th century. This article provides an exposition of the theory and a review of the associated data. In the past much ...

Visuospatial dysfunction in the neurodegenerative diseases.

Visuospatial dysfunction is not generally considered a cardinal feature of the common neurodegenerative disorders of late life like Alzheimers disease (AD), Parkinsons disease (PD), and Dementia with Lewy bodies (DLB). However, a large number of research ...
