EOG Pod
The EOG Pod utilizes the steady corneal-retinal potential in the detection of eye movement and position. The pod can also be used for EEG or EGG recordings.
Overview
The EOG Pod utilizes the steady corneal-retinal potential in the detection of eye movement and position. The pod can also be used for EEG or EGG recordings (contact your ADInstruments representative for further information).
Supplied with:
- Shielded Lead Wires, which snap connect to conductive (Ag/AgCl) adhesive electrodes
For use with:
- The Pod plugs directly into a PowerLab Pod port
- If you want to use the EOG Pod with a PowerLab or MacLab that has no Pod port, you will require the Pod Expander.

Key Features
- DC coupling with a fixed low-pass filter (500 Hz) to remove high frequencies.
- An offset knob to manually remove DC drift. The offset control provides ±15 mV of offset range (at input) for all range selections.
- Steady corneal-retinal potential (dipole) for the detection of eye movement and position.
