Figure 8

GAR-RMI, 554 days. (a) Side view of an electrode with a large longitudinal crack in the parylene adjacent to surface irregularities, scale 20 μm. (b) Top view of array showing sheets of fibrosis suspended between electrodes, scale 200 μm. (c) Cracked parylene along an electrode shaft with underlying silicon exposed and tissue invasion, scale 1 μm. (d) Side view of the array showing thick fibrous tissue suspended between electrodes. Note that the tissue is adherent halfway up the shaft, indicating that the electrode tips were not fully seated in the cortex, scale 100 μm. (e) A thin film of collagen is present along the base of the array. A crack in the parylene is also visible underneath this encapsulation tissue, scale 10 μm. All images in this figure were taken at 5 kV.
