Biophysics of Structure and Mechanism, 1977
1) The eye may be regarded as an automatic camera that keeps the average sensitivity near the middle of the working range. 2) Nerve signals are contrast-coded, and hence are not changed by changes in general illumination. 3) Rod thresholds can be raised three-fold by a background from which only 1% of the rods have caught one quantum.

Visualization is a powerful method to present and analyze a large amount of data. It is increasingly important in bioinformatics and is used for exploring different types of molecular biological data, such as structural information, high throughput data, and biochemical networks.

Proceedings of the 9th Augmented Human International Conference, 2018
Current practices in visual field tests require skilled eye care professionals and expensive machine setup in a controlled environment [1], thus, limit their availability within eye care clinics and hospitals. With a low-cost Virtual Reality (VR) device and its immersive capability, we developed Visual Field Visualizer (VFV), a prototype VR system that

Visual development is considered as a neurobiological process, integrated into developing systems for cognition, action and attention. The onset in early months of selective processing of orientation, motion, color and binocular vision, and of selective oculomotor control, reflect the emergence of cortical visual systems that modulate and control ...

Visualizing visual impairments
Gerontechnology, 2006We developed and evaluated methods to visualize the limitations of visually impaired persons. Three types of simulation were developed: (i) fixation independent, showing which elements remain visible after ample inspection, related to object recognition, (ii) fixation dependent, showing which elements remain visible in the entire visual field while ...

Visual imagery and visual representation
Trends in Neurosciences, 1994Among many controversies in visual neuroscience is whether visual imagery of objects, scenes and living beings is based upon contributions of the early visual areas or depends on hierarchical higher visual areas only, and whether the cortical areas subserving visual imagery are identical to those underlying visual perception.

Damage at many different locations within the visual system can result in visual deficits, and a knowledge of the anatomy involved makes it possible to understand these deficits. In this chapter, we will review the visual system from basic anatomy to the description of more complex higher visual function.

Visual Function Tests: Visual Fields
2022Visual field tests, also known as perimetry tests, are used to assess progression of ophthalmic diseases such as retinitis pigmentosa (RP) by monitoring changes in a patient's visual field (VF). VF loss corresponds to damage at any point in the visual pathway, including the retina, such as in RP. Damage to different parts of this pathway corresponds to

Domain-specific dataflow visual programming languages are now commonplace throughout the world of computing. Although not the earliest form of visual language (that honor, like so many others, of course is due to Sketchpad [27]) dataflow visual languages are now by far the most common form of visual programming language used in practice.

Selective visual attention, visual search and visual awareness
2004In a previous study, Butter and Goodale (2000) reported that visual search increases the identification of targets relative to distracters. The present series of studies investigated further this effect of search. Search increased identification of Ls when they were targets and decreased their identification when Ls were distracters in concurrent ...
