A Telemetry System for Neuronal Signal Acquiring and Processing

To collect neuronal activity data from awake, behaving freely animals, we developed miniaturized telemetry recording system. The integrated system consists of four major components: (1) microelectrodes and micro-driver assembly; (2) analog front end (AFE); (3) Programable system on chip (PSoC); (4) Radio transceiver and the LabVIEW used as a platform for the graphic user interface. The result showed the system was able to record and analyze neuronal recordings are made in freely moving animals and continuously for time periods of a week or more. This is very useful to study the interdisciplinary research of neuroscience and information engineering technique. The circuits and architecture of the devices can be adapted for neurobiology and research with other small animals.
