Visual Dysfunction in Posterior Cortical Atrophy

Frontiers in Neurology, 2017
Posterior cortical atrophy (PCA) is a syndromic diagnosis. It is characterized by progressive impairment of higher (cortical) visual function with imaging evidence of degeneration affecting the occipital, parietal, and posterior temporal lobes ...

An algorithm for visual fields

Survey of Ophthalmology, 1980
The authors present an algorithm, or sequential strategy, for the performance and interpretation of visual fields. Based on the principle that particular areas of the visual field are relatively vulnerable and that particular defect configurations are relatively more diagnostic, the strategy proposes certain "core maneuvers" for all initial ...

Eye position modulates retinotopic responses in early visual areas: a bias for the straight-ahead direction [PDF]

, 2014
Even though the eyes constantly change position, the location of a stimulus can be accurately represented by a population of neurons with retinotopic receptive fields modulated by eye position gain fields.

Human frontal eye fields and spatial priming of pop-out [PDF]

, 2007
"Priming of pop-out" is a form of implicit memory that facilitates detection of a recently inspected search target. Repeated presentation of a target's features or its spatial position improves detection speed (feature/spatial priming).

Role of Ganglionic Cell Complex, Retinal Nerve Fibre Layer in Glaucoma Evaluation [PDF]

Journal of Clinical and Diagnostic Research, 2020
Introduction: Glaucoma is a multifactorial disease characterised by damage to Retinal Ganglion Cells (RGCs) that inturn results in damage of nerve fibers resulting in functional visual impairment.

Visualizing the Computational Intelligence Field [PDF]

IEEE Computational Intelligence Magazine, 2006
In this paper, we visualize the structure and the evolution of the computational intelligence (CI) field. Based on our visualizations, we analyze the way in which the CI field is divided into several subfields. The visualizations provide insight into the characteristics of each subfield and into the relations between the subfields.

Exocentric Pointing in the Visual Field [PDF]

i-Perception, 2013
“Exocentric pointing in the visual field” involves the setting of a pointer so as to visually point to a target, where both pointer and target are objects in the visual field. Phenomenologically, such pointings show systematic deviations from veridicality of several degrees.
