Morphometric analyses of the visual pathways in macular degeneration

, 2014
Introduction. Macular degeneration (MD) causes central visual field loss. When field defects occur in both eyes and overlap, parts of the visual pathways are no longer stimulated.

Reciprocal anatomical relationship between primary sensory and prefrontal cortices in the human brain [PDF]

, 2011
The human brain exhibits remarkable interindividual variability in cortical architecture. Despite extensive evidence for the behavioral consequences of such anatomical variability in individual cortical regions, it is unclear whether and how different ...

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 ...

Being first matters: topographical representational similarity analysis of ERP signals reveals separate networks for audiovisual temporal binding depending on the leading sense [PDF]

, 2017
In multisensory integration, processing in one sensory modality is enhanced by complementary information from other modalities. Inter-sensory timing is crucial in this process as only inputs reaching the brain within a restricted temporal window are ...

Automatic Retinal Nerve Fiber Segmentation and the Influence of Intersubject Variability in Ocular Parameters on the Mapping of Retinal Sites to the Pointwise Orientation Angles

Journal of Imaging
The current study investigates the influence of intersubject variability in ocular characteristics on the mapping of visual field (VF) sites to the pointwise directional angles in retinal nerve fiber layer (RNFL) bundle traces.

Redundant neural vision systems: competing for collision recognition roles [PDF]

, 2013
Ability to detect collisions is vital for future robots that interact with humans in complex visual environments. Lobula giant movement detectors (LGMD) and directional selective neurons (DSNs) are two types of identified neurons found in the visual ...

Causal effect of COVID-19 on optic nerve and visual pathway disorders: genetic evidence of lung-brain axis

Frontiers in Immunology
PurposeTo investigate the potential causal association between COVID-19 exposure and optic nerve and visual pathway disorders through a two-sample bidirectional Mendelian randomization (MR) analysis, and to provide empirical support for the lung-brain ...

Structural Differences Across Multiple Visual Cortical Regions in the Absence of Cone Function in Congenital Achromatopsia

Frontiers in Neuroscience, 2021
Most individuals with congenital achromatopsia (ACHM) carry mutations that affect the retinal phototransduction pathway of cone photoreceptors, fundamental to both high acuity vision and colour perception. As the central fovea is occupied solely by cones,

A laminar organization for selective cortico-cortical communication [PDF]

, 2017
The neocortex is central to mammalian cognitive ability, playing critical roles in sensory perception, motor skills and executive function. This thin, layered structure comprises distinct, functionally specialized areas that communicate with each other ...

Pathos: a web facility that uses metabolic maps to display experimental changes in metabolites identified by mass spectrometry [PDF]

, 2011
This work describes a freely available web-based facility which can be used to analyse raw or processed mass spectrometric data from metabolomics experiments and display the metabolites identified – and changes in their experimental abundance – in the ...
