A new multi-unit acquisition system for free-moving animal using field programmable analog array and on chip MCU-Neuroscope1

Description

We designed a new multi-unit acquisition system for free-moving animals which breaks through the constraint of conventional multi-unit recording systems. To release those animals from thick electronic wires during experimentation, the IrDA infrared data communication, field programmable analog array (MPAA020) and 16 bit micro processor (H8), were used for the design. We summarize the related works for multi-unit recording techniques and point out the defects of those old techniques. Then the design of the system are introduced. As the results of the research, we checked the fidelity of recorded neural activity and the reliability of the data transmission.
