Reflections on the Utility of the Retina as a Biomarker for Alzheimer's Disease: A Literature Review. [PDF]

open access: yes, 2019
As a part of the central nervous system, the retina may reflect both physiologic processes and abnormalities related to diseases of the brain. Indeed, a concerted effort has been put forth to understand how Alzheimer's disease (AD) pathology may manifest

Neural ensemble decoding reveals a correlate of viewer- to object-centered spatial transformation in monkey parietal cortex [PDF]

open access: yes, 2008
The parietal cortex contains representations of space in multiple coordinate systems including retina-, head-, body-, and world-based systems. Previously, we found that when monkeys are required to perform spatial computations on objects, many neurons in

Epigenetics and cell death: DNA hypermethylation in programmed retinal cell death. [PDF]

open access: yes, 2013
BackgroundVertebrate genomes undergo epigenetic reprogramming during development and disease. Emerging evidence suggests that DNA methylation plays a key role in cell fate determination in the retina.

Non-viral delivery and optimized optogenetic stimulation of retinal ganglion cells led to behavioral restoration of vision [PDF]

open access: yes, 2012
Stimulation of retinal neurons using optogenetics via use of chanelrhodopsin-2 (ChR2) has opened up a new direction for restoration of vision for treatment of retinitis pigmentosa (RP).

Streaming an image through the eye: The retina seen as a dithered scalable image coder [PDF]

open access: yes, 2012
We propose the design of an original scalable image coder/decoder that is inspired from the mammalians retina. Our coder accounts for the time-dependent and also nondeterministic behavior of the actual retina.

Sphingolipids as emerging mediators in retina degeneration [PDF]

open access: yes, 2019
The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions.

Simulation and performance of an artificial retina for 40 MHz track reconstruction [PDF]

open access: yes, 2014
We present the results of a detailed simulation of the artificial retina pattern-recognition algorithm, designed to reconstruct events with hundreds of charged-particle tracks in pixel and silicon detectors at LHCb with LHC crossing frequency of $40\,\rm

How lateral inhibition and fast retinogeniculo-cortical oscillations create vision: A new hypothesis [PDF]

open access: yes, 2016
The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibition than previously proposed, 2) the role ...

In vivo human retinal and choroidal vasculature visualization using differential phase contrast swept source optical coherence tomography at 1060 nm [PDF]

open access: yes, 2012
A differential phase contrast (DPC) method is validated for in vivo human retinal and choroidal vasculature visualization using high-speed swept-source optical coherence tomography (SS-OCT) at 1060 nm.
