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.

Are v1 simple cells optimized for visual occlusions? : A comparative study

, 2013
: Simple cells in primary visual cortex were famously found to respond to low-level image components such as edges. Sparse coding and independent component analysis (ICA) emerged as the standard computational models for simple cell coding because they ...

Context Matters: The Illusive Simplicity of Macaque V1 Receptive Fields [PDF]

, 2012
Even in V1, where neurons have well characterized classical receptive fields (CRFs), it has been difficult to deduce which features of natural scenes stimuli they actually respond to.

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.

Timing of target discrimination in human frontal eye fields

, 2004
Frontal eye field (FEF) neurons discharge in response to behaviorally relevant stimuli that are potential targets for saccades. Distinct visual and motor processes have been dissociated in the FEF of macaque monkeys, but little is known about the visual ...

An overview of interactive visual data mining techniques for knowledge discovery [PDF]

, 2013
n the past decade, the analysis of data has faced the challenge of dealing with very large and complex datasets and the real-time generation of data. Technologies to store and access these complex and large datasets are in place.

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.

Tolosa-Hunt Syndrome in a Young Subject

Delhi Journal of Ophthalmology, 2022
Tolosa-Hunt syndrome (THS) is a non-specific inflammation of the cavernous sinus or superior orbital fissure which causes painful, usually unilateral ophthalmoparesis or ophthalmoplegia. A 22-year-old lady presented with diminution of vision, pain in her

Artifacts in Visual Fields

Delhi Journal of Ophthalmology
Visual field (VF) examination, as is well known, forms the key stone of management in glaucoma. However, this modality of investigation is not free of errors and artifacts.
