Visual pathways involvement in clinically isolated syndrome in children [PDF]

International Journal of Ophthalmology, 2015
AIM: To investigate extent and nature of visual pathways involvement in children with clinically isolated syndrome (CIS). METHODS: Forty-seven patients (age 11-17y) with CIS, which later proved to be multiple sclerosis (MS) onset, and 30 controls ...

Loss and enhancement of layer-selective signals in geniculostriate and corticotectal pathways of adult human amblyopia

Cell Reports, 2021
Summary: How abnormal visual experiences early in life influence human subcortical pathways is poorly understood. Using high-resolution fMRI and pathway-selective visual stimuli, we investigate the influence of amblyopia on response properties and the ...

Developmental Reorganisation of Visual Motion Pathways

i-Perception, 2012
In adults, visual form and motion activate independent networks of extrastriate areas which are roughly aligned with the ventral and dorsal streams, respectively.

Impaired communication between the dorsal and ventral stream: indications from apraxia

Frontiers in Human Neuroscience, 2016
Patients with apraxia perform poorly when demonstrating how an object is used, particularly when pantomiming the action. However, these patients are able to accurately identify, and to pick up and move objects, demonstrating intact ventral and dorsal ...

Educating the blind brain: a panorama of neural bases of vision and of training programs in organic neurovisual deficits

Frontiers in Integrative Neuroscience, 2014
Vision is a complex function, which is achieved by movements of the eyes to properly foveate targets at any location in 3D space and to continuously refresh neural information in the different visual pathways.

Functional 3-Dimensional Retinal Organoids: Technological Progress and Existing Challenges

Frontiers in Neuroscience, 2021
Stem cell scientists have developed methods for the self-formation of artificial organs, often referred to as organoids. Organoids can be used as model systems for research in multiple biological disciplines.

Devil in the Details – Visual Perception of the Landscape Features by Potential Residential Buyers

Real Estate Management and Valuation
It has long been established that people attach value to window views. However, the challenge in real estate market analyses is to capture what landscape features an attractive view contains and thus how they affect the worth (individual valuation) of ...

Cortical and white matter mapping in the visual system- more than meets theeye: on the importance of functional imaging to understand visual systempathologies

Frontiers in Integrative Neuroscience, 2014
Information transmission within the visual system is highly organized with the ultimate goal of accomplishing higher-order, complex visuo-spatial and object identity processing. Perception is dependent on the intactness of the entire system and damage at

Reconciling the Neurophysiological and Cognitive Theories of Stimulus–Response Spatial Compatibility Effects: A Visual–Motor Dissociation Approach

Vision
This study investigated the differential impact of two visual dimensions (direction and spatial location) in two spatial Stroop tasks, where the relevant dimension for the response varied.

I'll take the low road: The evolutionary underpinnings of visually triggered fear.

Frontiers in Neuroscience, 2015
Although there is general agreement that the central nucleus of the amygdala (CeA) is critical for triggering the neuroendocrine response to visual threats, there is uncertainty about the role of subcortical visual pathways in this process.
