A low-cost, multiplexed muECoG system for high-density recordings in freely moving rodents

Micro-electrocorticography (muECoG) offers a minimally invasive neural interface with high spatial resolution over large areas of cortex. However, electrode arrays with many contacts that are individually wired to external recording systems are cumbersome and make recordings in freely behaving rodents challenging. We report a novel high-density 60-electrode system for muECoG recording in freely moving rats.
