Introduction This paper presents the Argo System, an advanced, massively parallel neural recording system. It integrates platinum-iridium microwire electrode arrays with a CMOS voltage amplifier array. The Argo system represents a significant advancement in in vivo neural recording, achieving the highest channel count to date by enabling simultaneous recording from 65,536 channels at over 32 kHz and 12-bit resolution. Engineered for cortical recordings, it functions effectively with both penetrating and surface microelectrodes. Validation involved capturing spiking activity from 791 neurons in rats and cortical surface Local Field Potential (LFP) activity from over 30,000 channels in sheep. While presently configured for head-fixed recording, the microwire-CMOS design holds substantial promise for clinical application, laying the groundwork for future high data rate intracortical implants.
