Encyclopedia
John R. Hetling is an Associate Professor at the University of Illinois at Chicago
in the departments of Bioengineering http://www.uic.edu/depts/bioe/faculty/j_hetling/index.htm and Ophthalmology and Visual Sciences http://www.uic.edu/com/eye/VSRG/Faculty.shtml. He is also the Director of Undergraduate Studies for the Department of Bioengineering and the Director of the Laboratory of Neurotronic Communication http://www.uic.edu/depts/bioe/faculty/j_hetling/index.htm at UIC. He is a world leader and expert on neural prosthesis of the neural retina
and testing electrical stimulation devices in the retina. His research group has pioneered the use of intraretinal electroretinography
(ERG) as a means of directly testing the physiology of the neural retina. His specific research interests focus on the extraction of information from complex or inaccessible biological systems, specifically as it relates to phototransduction in living animals, and large pattern-generating neural networks

in 1989 with a degree in Biology, Hetling worked for two years in the neuroelectrophysiology laboratory of Patsy Dickinson at Bowdoin College
studying rhythmic motor pattern generation. He then began his PhD at UIC in 1991 in the laboratory of David R. Pepperberg, which he completed in 1998. Following his PhD he did a postdoctoral fellowship in the Department of Ophthalmology and Visual Sciences at UIC before being named a Visiting Assistant Professor in the Department of Bioengineering also at UIC. Hetling began his tenure track faculty position as an Assistant Professor at UIC in 1999.

Retina
The vertebrate retina is a light-sensitive tissue lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical...

Electroretinography
Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors , inner retinal cells , and the ganglion cells. Electrodes are usually placed on the cornea and the skin near the eye, although it is possible to record the ERG from skin electrodes...
