Fig. 7: Inflammatory Response to µECoG Array.

a DAPI, Iba1, and GFAP staining in the implanted cortex with the transparent µECoG array, showing markers for cell nuclei, microglia, and astrocytes, respectively. Scale bar = 100 µm. b DAPI, Iba1, and GFAP staining in the contralateral, non-implanted cortex for the transparent µECoG array, illustrating baseline levels of microglia and astrocytes (scale bar = 100 µm).
