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 …

Phosphene induction by microstimulation of macaque V1

EJ Tehovnik, WM Slocum - Brain research reviews, 2007 - Elsevier
Non-human primates are being used to develop a cortical visual prosthesis for the blind. We
use the properties of electrical microstimulation of striate cortex (area V1) of macaque …

Transcranial electrical stimulation over visual cortex evokes phosphenes with a retinal origin

K Kar, B Krekelberg - Journal of Neurophysiology, 2012 - journals.physiology.org
Transcranial electrical stimulation (tES) is a promising therapeutic tool for a range of
neurological diseases. Understanding how the small currents used in tES spread across the …

EJ Tehovnik, WM Slocum… - Journal of …, 2005 - journals.physiology.org
The purpose of this review is to critically examine phosphene induction and saccadic eye
movement generation by electrical microstimulation of striate cortex (area V1) in humans …

Microstimulation of V1 affects the detection of visual targets: manipulation of target contrast

EJ Tehovnik, WM Slocum - Experimental brain research, 2005 - Springer
Electrical microstimulation of the striate cortex (area V1) in monkeys delays the execution of
saccadic eye movements generated to a visual target located in the receptive field of the …

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 …

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 …

Delaying visually guided saccades by microstimulation of macaque V1: spatial properties of delay fields

EJ Tehovnik, WM Slocum… - European Journal of …, 2005 - Wiley Online Library
Electrical microstimulation of macaque primary visual cortex (area V1) is known to delay the
execution of saccadic eye movements made to a punctate visual target placed into the …

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
