By distributing multiple high-density extracellular micro-electrode arrays (MEAs) in vivo across the brain, each with 1000’s of sensing channels, neuroscientists have begun to map the correlation of neuronal activity across different brain regions, with single-neuron precision [1]. Since each neural sensing channel typically samples at 20 to 50kS/s with a >10b ADC, multiple MEAs
