Electrodes 43, 52, 53, and 84 show an increased noise level after a longer cycle of use. The bath was
grounded with the internal reference electrode 15. Time axis: 1000 ms, voltage axis: 50 μV. You should
ground some of the electrodes if you want to use this MEA for recording.
Same MEA, zoom to single channel # 22. Time axis: 500 ms, voltage axis: 20 μV.
Same MEA after grounding defective electrodes. Time axis: 1000 ms, voltage axis: 100 μV.
Typical noise level of a standard 60MEA200/10iR-Ti (round 10 μm Tin electrodes)
Noise level of a new standard 60MEA200/10iR-Ti. Bath grounded with the internal reference
electrode 15. Time axis: 1000 ms, voltage axis: 100 μV.
