What This Manual Covers 

The Blackrock CerePlex µ provides an interface between the Cerebus recording system 

or the CerePlex Direct recording system for high fidelity transmission and recording of 

extracellular spikes and local field potentials from the brain.  The Blackrock CerePlex µ 

converts analog signals to digital format right at the recording site which dramatically 

reduces the noise introduced to the signal during transmission. Moreover, the motion 

sensor on the CerePlex µ provides 3-axis accelerometer and 3-axis gyroscope at the 

headstage.
