The luminance-response function of the photopic negative response (PhNR): analysing different stimulation, recording and measurement approaches

Key Points

To analyze different stimulation, recording, and measurement approaches of the photopic negative response (PhNR).
Varying temporal frequency of stimulation up to 4 Hz
Comparing skin electrode recordings to corneal fibre electrodes
Measuring PhNR amplitude relative to b-wave and baseline
Significant increase in temporal frequency without compromising PhNR
Lower variance in PhNR with skin electrode recordings
Higher amplitude measurements observed with b-wave compared to corneal electrodes

Abstract

This study demonstrates that temporal frequency can be increased significantly, optimally at 4 Hz, without compromising the PhNR. PhNR variance is lower with skin electrode recordings and PhNR amplitude measurements from the b-wave compared to corneal fibre electrodes and baseline-PhNR amplitudes.
