Data Acquisition Software
Cerebus® Central Suite
Installation
To install the software suite, make sure any previous version of the software is uninstalled. Run the Cerebus-
Central-Suite msi program from the supplied Installation CD and follow the instructions. The Cerebus® Central
Suite consists of several applications that perform various functions. To run these apps first run the Central shortcut
via the Start Menu.
Additionally, you must run MCRInstaller program from the supplied Installation CD to install MATLAB Compiler
Runtime. This is a required component for Cerebus® Central Suite.
You may download MCRInstaller from www.blackrockmicro.com/mcr/
Sorting Algorithms
The program can sort detected action potentials using three real-time sorting algorithms.
o Hoops: This is a manual method. A time-amplitude algorithm, which involves manually placing “hoops” to specify
where the detected spike waveform must go through to be classified as a defined unit.
o Manual PCA: This is a manual method. The system calculates the first three principle components on a representative
sample group then projects each new waveform into the same 3D PCA space. The user draws an ellipsoid around each
cluster to sort the group.
o Histogram Peak Count: This is an automatic method. The sorting algorithm is described in Spike Sorting on page 36.
Sampling Rates
The NSP is capable of processing signals at rates up to 30 kS/s.
o None: Continuous data is not recorded.
o 500 S/s: Records at 500 samples/second. Channels recorded at this frequency will be saved in the NS1 file.
o 1 kS/s: Records at 1k samples/second. Channels recorded at this frequency will be saved in the NS2 file.
o 2 kS/s: Records at 2k samples/second. Channels recorded at this frequency will be saved in the NS3 file.
o 10 kS/s: Records at 10k samples/second. Channels recorded at this frequency will be saved in the NS4 file.
o 30 kS/s: Records at 30k samples/second. Channels recorded at this frequency will be saved in the NS5 file.
o 30 kS/s: Records the raw data at 30k samples/second. The data in this stream is not digitally filtered. Channels recorded
at this frequency will be saved in the NS6 file.
