Intraoperative monitoring of flash visual evoked potential under general anesthesia [PDF]

open access: yesKorean Journal of Anesthesiology, 2017
In neurosurgical procedures that may cause visual impairment in the intraoperative period, the monitoring of flash visual evoked potential (VEP) is clinically used to evaluate visual function.

Functional and Neural Mechanisms of Out-of-Body Experiences: Importance of Retinogeniculo-Cortical Oscillations [PDF]

open access: yes, 2016
Current research on the various forms of autoscopic phenomena addresses the clinical and neurological correlates of out-of-body experiences, autoscopic hallucinations,and heautoscopy.

Visual imaging as a predictor of neurodegeneration in experimental autoimmune demyelination and multiple sclerosis

open access: yesActa Neuropathologica Communications, 2022
Thalamic volume is associated with clinical disability in multiple sclerosis (MS) and is vulnerable to secondary neurodegeneration due to its extensive connectivity throughout the central nervous system (CNS).

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 ...

Giant petrous bone cholesteatoma: combined microscopic surgery and an adjuvant endoscopic approach [PDF]

open access: yes, 2016
Petrous bone cholesteatomas (PBCs) are epidermoid cysts, which have developed in the petrous portion of the temporal bone and may be congenital or acquired.

Washed Microbiota Transplantation Accelerates the Recovery of Abnormal Changes by Light-Induced Stress in Tree Shrews

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
The gut and brain interact constantly in a complex fashion. Its intricacy and intrigue is progressively being revealed in the study of the “gut–brain axis”.

Morphometric analyses of the visual pathways in macular degeneration

open access: yes, 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.

Dendritic and axonal targeting patterns of a genetically-specified class of retinal ganglion cells that participate in image-forming circuits. [PDF]

open access: yes, 2014
BackgroundThere are numerous functional types of retinal ganglion cells (RGCs), each participating in circuits that encode a specific aspect of the visual scene.

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 ...

Evolution of mammalian sensorimotor cortex: Thalamic projections to parietal cortical areas in Monodelphis domestica

open access: yesFrontiers in Neuroanatomy, 2015
The current experiments build upon previous studies designed to reveal the network of parietal cortical areas present in the common mammalian ancestor. Understanding this ancestral network is essential for highlighting the basic somatosensory circuitry ...
