Demonstration of artificial visual percepts generated through thalamic microstimulation

JS Pezaris, RC Reid - … of the National Academy of Sciences, 2007 - National Acad Sciences
Electrical stimulation of the visual system might serve as the foundation for a prosthetic
device for the blind. We examined whether microstimulation of the dorsal lateral geniculate …

Microstimulation of visual cortex to restore vision

EJ Tehovnik, WM Slocum, SM Smirnakis… - Progress in brain …, 2009 - Elsevier
This review argues that one reason why a functional visuo-cortical prosthetic device has not
been developed to restore even minimal vision to blind individuals is because there is no …

New methods devised specify the size and color of the spots monkeys see when striate cortex (area V1) is electrically stimulated

PH Schiller, WM Slocum, MC Kwak… - Proceedings of the …, 2011 - National Acad Sciences
Creating a prosthetic device for the blind is a central future task. Our research examines the
feasibility of producing a prosthetic device based on electrical stimulation of primary visual …

Spatial and temporal characteristics of V1 microstimulation during chronic implantation of a microelectrode array in a behaving macaque

TS Davis, RA Parker, PA House, E Bagley… - Journal of neural …, 2012 - iopscience.iop.org
Objective. It has been hypothesized that a vision prosthesis capable of evoking useful visual
percepts can be based upon electrically stimulating the primary visual cortex (V1) of a blind …

A model for intracortical visual prosthesis research

P Troyk, M Bak, J Berg, D Bradley, S Cogan… - Artificial …, 2003 - Wiley Online Library
In the field of visual prosthesis research, it has generally been held that animal models are
limited to testing the safety of implantable hardware due to the inability of the animal to …

Electrical stimulation with a penetrating optic nerve electrode array elicits visuotopic cortical responses in cats

perceptions can be produced using high-electrode-count arrays of penetrating …

Visual prosthesis

PH Schiller, EJ Tehovnik - Perception, 2008 - journals.sagepub.com
There are more than forty million blind individuals in the world whose plight would be greatly
ameliorated by creating a visual prosthesis. We begin by outlining the basic operational …

Electrical induction of vision

EJ Tehovnik, WM Slocum - Neuroscience & Biobehavioral Reviews, 2013 - Elsevier
We assess what monkeys see during electrical stimulation of primary visual cortex (area V1)
and relate the findings to visual percepts evoked electrically from human V1. Discussed …
