Extracellular recording is a key technology to study many types of brain functions. However the amplitudes of extracellular spikes are typically about 100 μV and should be picked up and amplified specially,then recorded and analyzed online. Most of the equipments for extracellular recording are either very expensive,or too large for recording in the brains of freely moving small animals. In this paper we developed a practical multi-electrode recording system based on virtual testing technology. The system i...
