Fig. 6: Imaging and LFP recordings of the neural probe on the cortex of a mouse.

From: Fabrication and in vivo 2-photon microscopy validation of transparent PEDOT:PSS microelectrode arrays

Fig. 6

a Infrared image of the probe on the cortex (6 out of 16 electrodes are shown). The colored regions of interest indicate the areas used to calculate the PEDOT:PSS transparencies values, which are based on the gray levels compared to adjacent areas that are not covered by PEDOT:PSS. b Infrared image of the probe on the cortex (4 out of 16 electrodes are shown); the white arrows indicate the gold interconnects. c and d 2-photon images with the focus plane on the probe. e 2-photon image with the focus plane 270 µm beneath the probe. f and g LFP recordings from the electrodes in (d) and (e), respectively.
