Abstract:

The objective of the proposed research is to develop a miniaturized, fully-integrated, high-channel-count, wirelessly-powered, implantable trimodal neural interface device, equipped with neural recording, electrical stimulation, and optogenetic stimulation capabilities, all integrated in the same device. The trimodal device, integrating high-density microelectrodes, individually addressable µLEDs, ultra-low-power SoC, and wireless telemetry, forms the most comprehensive interface. Moreover, this interface, which is compatible with the EnerCage-HC2 system, can cover the cortical surface to enable selective optical/electrical stimulation and recording of the large-scale cortical networks initially in small freely behaving animals.
