This work presents a novel micro-drive system designed to facilitate long-term investigations into rodent neural activity through the combined use of infrared neuromodulation and electrophysiological recording. Our innovative approach comprises a 3D-printed micro-drive, securely attached to the rodent's skull, along with a protective head stage to ensure the integrity of the micro-drive and the attached optical electrode (optrode) during unrestricted movement of the animal. The micro-drive interface serves as a precise tool, enabling researchers the ability to exercise fine control over the penetration depth of the optrode. This capability enables targeted neuromodulation and simultaneous electrophysiological recordings with the optrode in freely moving rodents. This micro-drive's unique modular design promotes the reusability and reimplantability of the optrode, thereby facilitating multiple experiments over an extended period of time. Several tests have been conducted to evaluate the accuracy and durability of the micro-drive, considering both physical and biological aspects. The smoothness of the insertion mechanism has been thoroughly evaluated to ensure minimal disruption during experimental procedures. The implanted micro-drive system allowed us to record single- and multi-unit activity during infrared stimulation for several days in freely moving rats. Overall, our 3D-printed micro-drive and head stage system presents a valuable tool for researchers seeking reliable and cost-effective solutions for long-term neuroscientific studies in freely moving rodents. The combination of innovative fabrication methods and comprehensive testing ensures the efficacy and versatility of the proposed interface, opening new possibilities for exploring neural circuitry and behaviour in a dynamic and physiologically relevant context.
