1 Introduction Understanding the dynamics of neural circuit activity underlying various brain functions requires long-term monitoring of neuronal spiking over large populations of neurons with high spatial and temporal resolution.[1-3] Existing implanted electrodes, including those capable of nonsuperficial recording of SU activity with sub-millisecond resolution, have greatly contributed to both basic and applied neuroscience.[4-11] Conventional electrodes are mainly metal wire-based arrays...
