I want to understand what the electrode impedance values given on spec sheet mean. Just looking to gain a general understanding and what voltages/ currents I can or cannot use. The electrodes are used to record voltage spikes of around 50-90 mV.
"""Electrode Diameter: 10 um or 30 um
Electrode impedance: <100 kilo ohms for 30 um electrodes....250-400 kilo ohms for 10 um electrodes"""
