Neuronal survival around the electrode. Uninjured control is indicated by the green dotted line. Black arrows indicate distances (0–50, 50–100 µm) at which uncoated samples were significantly lower than uninjured control (p < 0.05), whereas the blue arrow indicates distance (0–50 µm) at which PEG was different from uninjured control (p < 0.05). PEG+IL-1Ra was not significantly different from the uninjured control for any distance analyzed. At distances greater than 100 µm from the implant, all groups were equivalent to uninjured control.
