Synaptic plasticity onto inhibitory neurons as a mechanism for ocular dominance plasticity.

PLoS Computational Biology, 2019
Ocular dominance plasticity is a well-documented phenomenon allowing us to study properties of cortical maturation. Understanding this maturation might be an important step towards unravelling how cortical circuits function.

Pinwheel Stabilization by Ocular Dominance Segregation [PDF]

Physical Review Letters, 2009
We present an analytical approach for studying the coupled development of ocular dominance and orientation preference columns. Using this approach we demonstrate that ocular dominance segregation can induce the stabilization and even the production of pinwheels by their crystallization in two types of periodic lattices. Pinwheel crystallization depends

Ocular Dominance Columns: Enigmas and Challenges [PDF]

The Neuroscientist, 2008
In some mammalian species, geniculocortical afferents serving each eye are segregated in layer 4C of striate cortex into stripes called ocular dominance columns. Having described the complete pattern of ocular dominance columns in the human brain, the authors enumerate here the principal enigmas that confront future investigators.

Internal neural states influence the short-term effect of monocular deprivation in human adults

eLife, 2023
The adult human visual system maintains the ability to be altered by sensory deprivation. What has not been considered is whether the internal neural states modulate visual sensitivity to short-term monocular deprivation. In this study we manipulated the

Ocular dominance and its association with retinal thickness profile – A cross-sectional study

Indian Journal of Ophthalmology
Purpose: The retinal thickness profile is essential for detecting ocular diseases like glaucoma and other optic neuropathies. The retinal nerve fiber layer (RNFL) thickness is affected by age, ethnicity, axial length, optic disc area, and inter-eye ...

Intrinsic-signal optical imaging reveals cryptic ocular dominance columns in primary visual cortex of new world owl monkeys

Frontiers in Neuroscience, 2007
A significant concept in neuroscience is that sensory areas of the neocortex have evolved the remarkable ability to represent a number of stimulus features within the confines of a global map of the sensory periphery.

Postoperative Change in Ocular Torsion in Intermittent Exotropia: Relationship with Postoperative Surgical Outcomes. [PDF]

PLoS ONE, 2016
The aim of this study was to determine whether objective ocular torsion in intermittent exotropia (IXT) changes after recession surgery, and to evaluate the relationship between change in ocular torsion and clinical parameters in IXT.

Effect of Ocular Dominance on Ocular Blood Flow Parameters

Cureus, 2023
In binocular vision, there is a dominant eye and a nondominant eye, a phenomenon termed ocular dominance. This study determined the differences and associations of the ocular blood flow parameters between dominant and nondominant eyes in healthy Japanese subjects.This cross-sectional study included 128 eyes of 64 subjects (13 male and 51 female) aged ≥

Strabismic amblyopia regression post refractive surgery

Journal of Ophthalmology, 2020
Background. Refractive laser surgery has absolute and relative contraindications. Among the relative ones is amblyopia and a history of strabismus. Caution should also be in cause of trauma, scar, or leukoma in the ablation site. Purpose. To present

Macular asymmetry analysis in sighting ocular dominance

Kaohsiung Journal of Medical Sciences, 2014
Sighting ocular dominance is the preference of one eye over the other in terms of sighting. In this study, our aim was to examine differences in interocular and intraocular macular thickness, interocular fovea-optic disc angle, and foveal blood vessel ...
