Deterioration of FP recordings yield over time. (A) An example of the deterioration of the averaged, sorted FPs recorded by a PPMP implant at one hour, 2, 4 and 7 days after platform implantation. (B) Out of the 24 implanted PPMPs (1 h after implantation) 91% of the electrodes were viable (blue). With time, the number of operative implants and the number of viable electrodes decreased. An implant is defined as operational if at least one electrode is viable. The percentage of viable electrodes (blue), at a given point in time, is defined as the number of viable electrodes out of the number of operating implants at that point in time X 15 electrodes/implant.
