Visualizing the visual system [PDF]

open access: yesNeurocomputing, 2000
As part of a forthcoming planetarium show about the human brain, we are producing realistic models of the central nervous system at a variety of scales, from whole brain images to images of individual neurons. We have focused on the visual system and especially the visual cortex, and are building sets of simulated neurons using stochastic growth rules ...

Sentinels in the visual system [PDF]

open access: yesFrontiers in Behavioral Neuroscience, 2011
The human visual system, like that of other mammals, comprises a multiplicity of par-allel visual pathways of old evolutionary origin that bypass the primary visual cortex (V1; Milner and Goodale, 2006; Tamietto and de Gelder, 2010). We currently know very little about these V1-independent pathways, but it makes sense from an evolu-tionary standpoint ...

The effect of time since stroke, gender, age, and lesion size on thalamus volume in chronic stroke: a pilot study

open access: yesScientific Reports, 2020
Recent stroke studies have shown that the ipsi-lesional thalamus longitudinally and significantly decreases after stroke in the acute and subacute stages.

Visual Field Coordinate Systems in Visual Neurophysiology [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
In this work, algorithms have been developed to: 1. Compare visual field coordinate data, presented in different representation systems; 2. Determine the distance in degrees between any two points in the visual field; 3.

Recognition of the Components of the Urban Landscape Visual System Elements and Values [PDF]

open access: yesمنظر, 2023
Urban landscape, as the consequence of the human perception of diverse dimensions of the city, the physical form, action, and meaning, is an objective-subjective phenomenon.

Retinal arterial–venous pulse delay: a new specific marker for a carotid–cavernous fistula

open access: yesFrontiers in Ophthalmology, 2023
PurposeThe purpose of the study was to describe ocular blood flow changes in eyes affected by a carotid–cavernous fistula (CCF) using laser speckle flowgraphy.

Development of a rapid point-of-care patient reported outcome measure for cataract surgery in India

open access: yesHealth and Quality of Life Outcomes, 2018
Background For patient undergoing cataract surgery in India, existing patient-reported outcome (PRO) measures are either not culturally relevant, have not been adequately validated, or are too long to be used in a busy clinical setting.

Visualizing system latency [PDF]

open access: yesCommunications of the ACM, 2010
Heat maps are a unique and powerful way to visualize latency data. Explaining the results, however, is an ongoing challenge.

Fourier Motion Processing in the Optic Tectum and Pretectum of the Zebrafish Larva

open access: yesFrontiers in Neural Circuits, 2022
In the presence of moving visual stimuli, the majority of animals follow the Fourier motion energy (luminance), independently of other stimulus features (edges, contrast, etc.). While the behavioral response to Fourier motion has been studied in the past,
