a Photograph of the 32-ch Au electrode array and hybrid graphene electrode array placed on the somatosensory system. b Neural activity under anesthesia. c Interictal-like activities recorded by both electrode types placed on the same hemisphere. d Comparison of the signal-to-noise ratio (SNR) of the hybrid graphene electrodes with SNRs from electrodes in previous studies. The hybrid electrode shows a higher SNR. e Ictal-like busting activity recorded by the hybrid graphene electrode after topical application of bicuculline.
