Graphene could address some challenges which current neural interfaces are facing. For instance, graphene-based field effect transistors (gFETs) can record brain signals at infraslow frequencies while reduced graphene oxide (rGO) microelectrodes display high charge injection enabling focal electrical stimulation. Here, we assessed the potential of different graphene-based electrodes for recording and stimulation in rodents, with functional ultrasound imaging (fUS) to quantify cerebral neural activity as read-out on visual cortex activity. In our first project we investigated how fast and slow
