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

open access: yes, 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 ...

Normative theory of visual receptive fields

open access: yes, 2021
This article gives an overview of a normative theory of visual receptive fields. We describe how idealized functional models of early spatial, spatio-chromatic and spatio-temporal receptive fields can be derived in a principled way, based on a set of ...

A novel interhemispheric interaction: modulation of neuronal cooperativity in the visual areas [PDF]

open access: yes, 2007
Background: The cortical representation of the visual field is split along the vertical midline, with the left and the right hemi-fields projecting to separate hemispheres. Connections between the visual areas of the two hemispheres are abundant near the

Timing of target discrimination in human frontal eye fields [PDF]

open access: yes, 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 ...

Using Visual Tools for Analysis and Learning [PDF]

open access: yes, 2010
This pack is intended as a resource for lecturers and students to facilitate the further development of their learning and teaching strategies. Visual tools were initially introduced within a module of the Year 3 nursing curriculum within the University ...

Vision through Healthy Aging Eyes

open access: yesVision, 2021
As life expectancy grows, so too will the number of people adversely affected by age. Although it is acknowledged that many conditions and diseases are associated with age, this mini-review will present a current update of the various visual changes that

Injuries to the Immature Optic Radiation Show Correlated Thinning of the Macular Ganglion Cell Layer

open access: yesFrontiers in Neurology, 2018
Injuries to the immature optic radiation (OR) are associated with thinning of the retinal nerve fiber layer and corresponding visual field (VF) defects.

Modeling Reactive Oxygen Species-Induced Axonal Loss in Leber Hereditary Optic Neuropathy

open access: yesBiomolecules, 2022
Leber hereditary optic neuropathy (LHON) is a rare syndrome that results in vision loss. A necessary but not sufficient condition for its onset is the existence of known mitochondrial DNA mutations that affect complex I biomolecular structure.

Cortical control of smooth pursuit eye movements [PDF]

open access: yes, 2007
In this PhD project, the functions of cortical regions that control smooth pursuit eye movements (SPEM) and visual attention were investigated. Combining behavioural (eye movement) measurements and functional magnetic resonance imaging (fMRI) the ...

Retinal Nerve Fiber Layer Thickness Measured by Optical Coherence Tomography in Non-glaucomatous Taiwanese

open access: yesJournal of the Formosan Medical Association, 2008
Background/Purpose: Assessment of the peripapillary retinal nerve fiber layer (RNFL) is essential for neuroretinal diseases, especially for early prediction of glaucomatous damage. The purpose of this study wasto measure RNFL thickness by Stratus optical
