ERG

Overview

iWorx systems, recorders and software have been used for recording ERGs in rodents and insects as noted in these Citations.

Amplifiers

DP-301 AmplifierDifferential Amplifier (DP-301) by Warner Instruments
The DP-301 is a single channel AC/DC differential pre-amplifier highly suited for EEG, EKG and extracellular recording.

 

Differential Amplifier (Model 3000) by A-M Systems
The Model 3000 High-Gain AC/DC Differential Amplifier is designed for low-noise recordings from excitable tissue. Specific applications include EEG, EKG, extracelluar recordings, and more.

Recorders

KIX-RA-834 8 Channel RecorderiWorx IX-RA-834 8 Channel Recorder
The iWorx RA-834C Recorder is the most advanced and feature-rich physiological data acquisition system on the market.

 

IX-400 Series Recorder

iWorx IX-400 Series Recorders
The iWorx 400 Series recorders are economical, high performance four, eight or sixteen channel data recorders for use with a broad range of analog amplifiers.

Software

An electroretinogram (ERG) is a recording of the electrical responses of the cells of the retina to a light stimulus. ERG parameters are detected, and functions derived from those parameters are computed in LabScribe’s ERG Advanced Analysis Module.
