Archives of Ophthalmology, 1929
The object of this paper is to give the present state of knowledge concerning the central visual pathways, the geniculocalcarine tract as well as the visual cortex. So much has been accomplished in this field within the last two decades that it seems justifiable to make a survey of all of the material that has been published in connection with the ...

Macular drusen and the sensitivity of the central visual field
Documenta Ophthalmologica, 1994Macular drusen are one of the earliest signs of age-related macular degeneration but little information is available on the functional aspects of macular area in patients with drusen. To determine if drusen are associated with changes in central visual field sensitivity, one eye of each of 35 subjects (mean age 64.9 years) with bilateral drusen and ...

Central Visual Persistences: I. Visual and Kinesthetic Interactions
Perception, 2005Phenomena associated with ‘central visual persistences’ (CPs) are new to both medical and psychological literature. Five subjects have reported similar CPs: positive afterimages following brief fixation of high-contrast objects or drawings and eye closure. CPs duplicate shapes and colors of single objects, lasting for about 15 s.

Visual Servoing with Central Catadioptric Camera
2006In this chapter we present an epipolar-based visual servoing for holonomic mobile robots equipped with panoramic camera. The proposed visual servoing is based on epipolar geometry and exploits the auto-epipolar property, a special configuration for the epipoles that occurs when the desired and the current panoramic views undergo a pure translation ...

Centrality Based Visualization of Small World Graphs
Computer Graphics Forum, 2008AbstractCurrent graph drawing algorithms enable the creation of two dimensional node‐link diagrams of huge graphs. However, for graphs with low diameter (of which “small world” graphs are a subset) these techniques begin to break down visually even when the graph has only a few hundred nodes. Typical algorithms produce images where nodes clump together

STUDIES ON THE CENTRAL VISUAL SYSTEM
Archives of Neurology & Psychiatry, 1926An understanding of the relations of the central visual system of animals will doubtless aid our appreciation of the precise conditions in the human brain. The visual pathways of animals can be accurately determined by the study of experimentally produced degenerations, as is shown by the experiments of Minkowski1on the geniculocortical connections in ...

STUDIES ON THE CENTRAL VISUAL CONNECTIONS
Archives of Neurology & Psychiatry, 1926Until within a decade it could still be considered an open question whether the visual center was limited to a definite portion of the occipital lobe, and whether there existed a projection of the retinal quadrants on the corpus geniculatum and cortex.

Neurons of the Central Visual System
1971Progressive development of the cerebral cortex in mammals in the course of evolution takes place through many interdependent processes. The surface area of the cortex is increased by the formation of fissures and gyri. The fissures and gyri are formed as a result of an increase in the number of neurons and of their long processes forming the white ...
