"After using the Riverbend Artifact Zapper for several years, I have found it to be indispensable for performing recording studies that involve antidromic and orthodromic stimulation. The Zapper easily and instantly erases much or all of the stimulus artifact, that is otherwise such a nuisance. It is simple to use and easily permits different strengths of zapping depending on the needs of a particular experiment. I have one in every lab." -Dr. Marc Sommer Center for Neural Basis of Cognition University of Pittsburgh "The Riverbend eye coil system is simply great. They are reliable, inexpensive and well designed. As if that wasn't enough the company really stands behind their products. I'd recommend them to anyone." -Dr. Paul Glimcher Associate Professor of Neural Science New York University "We've been using a Riverbend eye coil system since 1998 and we've been extremely pleased with its performance. When our lab expanded in 2005, the decision to get additional systems from Riverbend was a no-brainer. Our new systems arrived on schedule and they've all worked without a hitch. Most importantly, Dick has always responded to our inquiries promptly, thoroughly and courteously." -Dr. Richard Krauzlis Salk Institute USA Baylor University Carnegie-Mellon University Columbia University Dartmouth College Duke University.
