From: A softening laminar electrode for recording single unit activity from the rat hippocampus
Impedance magnitude (A) and phase angle (B) of all 8 recording sites of the array. Grey lines represent single recording sites; the black, orange, blue and green lines are the average values of all sites, on the first day, the 11st day of soaking, with platinized coating and after the in vivo implantation respectively. Impedance magnitude measured in the soaking test at 1 kHz before electroplating is plotted against time (C). Change in this values throughout the lifecycle of the recording sites of two implanted probes are compared (D).
