Extended Data Fig. 6: Intimate interface between chronically implanted spiral thread and neural tissue.
From: Flexible kirigami microelectrode arrays for neuronal activity recordings in non-human primate brains
a, Three-dimensional reconstructed image of a cleared 500-μm-thick brain slice with an implanted spiral thread. The self-fluorescent polyimide structure was imaged using 568 nm excitation. YFP-expressing neurons were imaged using 514 nm excitation. Green: neurons; Red: auto-fluorescence from polyimide. Scale bar, 200 μm. b, Zoom-in views showing the intimate interface between chronically implanted spiral thread and neural tissue. Scale bars, 100 μm.
