Secondary post-geniculate involvement in Leber's hereditary optic neuropathy.

open access: yesPLoS ONE, 2012
Leber's hereditary optic neuropathy (LHON) is characterized by retinal ganglion cell (RGC) degeneration with the preferential involvement of those forming the papillomacular bundle. The optic nerve is considered the main pathological target for LHON. Our

Visual deprivation modifies oscillatory activity in visual and auditory centers

open access: yesAnimal Cells and Systems, 2018
Loss of vision may enhance the capabilities of auditory perception, but the mechanisms mediating these changes remain elusive. Here, visual deprivation in rats resulted in altered oscillatory activities, which appeared to be the result of a common ...

A Neural Network Model for the Development of Simple and Complex Cell Receptive Fields Within Cortical Maps of Orientation and Ocular Dominance [PDF]

open access: yes, 1996
Prenatal development of the primary visual cortex leads to simple cells with spatially distinct and oriented ON and OFF subregions. These simple cells are organized into spatial maps of orientation and ocular dominance that exhibit singularities ...

Varicella-zoster virus reactivation from multiple ganglia: a case report

open access: yesJournal of Medical Case Reports, 2009
Introduction Simultaneous involvements of multiple cranial nerve ganglia (geniculate ganglion and peripheral ganglia of cranial nerves VIII, IX and X) by varicella-zoster virus and its subsequent activation may result in the characteristic eruptions of ...

Neuron analysis of visual perception [PDF]

open access: yes
The receptive fields of single cells in the visual system of cat and squirrel monkey were studied investigating the vestibular input affecting the cells, and the cell's responses during visual discrimination learning process.

A connectomic approach to the lateral geniculate nucleus [PDF]

open access: yesVisual Neuroscience, 2017
AbstractAlthough the core functions and structure of the lateral geniculate nucleus (LGN) are well understood, this core is surrounded by questions about the integration of feedforward and feedback connections, interactions between different channels of information, and how activity dependent development restructures synaptic networks.

Effect of Auditory Cortex Deactivation on Stimulus-Specific Adaptation in the Medial Geniculate Body

open access: yesJournal of Neuroscience, 2011
An animal's survival may depend on detecting new events or objects in its environment, and it is likely that the brain has evolved specific mechanisms to detect such changes.
