Right lateral geniculate nucleus infarct presenting as a left monocular temporal hemianopia

open access: yesClinical Case Reports, 2019
A lesion to the right lateral geniculate nucleus should cause a complete left monocular hemianopia. We present a case of a patient with left eye monocular temporal hemianopia with two MRIs demonstrating an ischemic defect at the right lateral geniculate ...

Functional evidence for cone-specific connectivity in the human retina [PDF]

open access: yes, 2009
NoPhysiological studies of colour vision have not yet resolved the controversial issue of how chromatic opponency is constructed at a neuronal level. Two competing theories, the cone-selective hypothesis and the random-wiring hypothesis, are currently ...

A case with Herpes Zoster Oticus involving multipl cranial nerves

open access: yesTurkish Archives of Otorhinolaryngology, 2012
Herpes Zoster Oticus described a virus caused by facial nerve paralysis associated with herpetic eruption of the pinna and suggested that it resulted from a geniculate ganglionitis.

The connections of the inferior colliculus and the organization of the brainstem auditory system in the greater horseshoe bat (Rhinolophus ferrumequinum) [PDF]

open access: yes, 1981
The connections of the inferior colliculus, the mammalian midbrain auditory center, were determined in the greater horseshoe bat (Rhinolophus ferrumequinum), using the horseradish peroxidase method.

A computational study of how orientation bias in the lateral geniculate nucleus can give rise to orientation selectivity in primary visual cortex

open access: yesFrontiers in Systems Neuroscience, 2011
Controversy remains about how orientation selectivity emerges in simple cells of the mammalian primary visual cortex. In this paper, we present a computational model of how the orientation-biased responses of cells in lateral geniculate nucleus can ...

Parvalbumin increases in the medial and lateral geniculate nuclei of aged rhesus macaques.

open access: yesFrontiers in Aging Neuroscience, 2013
Subcortical auditory structures in the macaque auditory system increase their densities of neurons expressing the calcium binding protein parvalbumin (PV) with age.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

open access: yesThe Anatomical Record, EarlyView.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Neurobiology of dyslexia : A reinterpretation of the data [PDF]

open access: yes, 2004
Theories of developmental dyslexia differ on how to best interpret the great variety of symptoms (linguistic, sensory, motor) observed in dyslexic individuals. One approach views dyslexia as a specific phonological deficit, which sometimes co-occurs with

From retinal waves to activity-dependent retinogeniculate map development. [PDF]

open access: yesPLoS ONE, 2012
A neural model is described of how spontaneous retinal waves are formed in infant mammals, and how these waves organize activity-dependent development of a topographic map in the lateral geniculate nucleus, with connections from each eye segregated into ...

Visualization of the Medial and Lateral Geniculate Nucleus on Phase Difference Enhanced Imaging

open access: yesAmerican Journal of Neuroradiology, 2015
BACKGROUND AND PURPOSE: The precise identification and measurement of the medial geniculate nucleus and lateral geniculate nucleus on MR imaging remain technically challenging because the thalamic nuclei are small structures.
