BIOPAC

From Waisman Brain Imaging Wiki

The BIOPAC amps are used in the Keck EEG Room and in Brogden 2 to record non-EEG biological signals. They replace the old HEM / James Long systems. The system in Keck is an MP-150; it communicates with the recording PC via ethernet, and can handle very high data rates from many channels at once. It currently has 8 data collection modules connected to it. The system in Brogden 2 is an MP-100; it communicates via a serial port connected to a USB adapter; it can handle high data rates from a dozen or more channels (but far more than we're likely to ever need). It currently has 5 data collection modules connected to it. All of the data collection modules are suitable for EEG, startle, and similar measurements.

They are made by BIOPAC Systems, Inc. (http://biopac.com/mp100_enter.htm)

Although the names and functions are similar, the BIOPAC amps are not the same as the BioSemi amps.

Our Tips & Tweaks

  • NOTE: The AcqKnowledge data aquisition and processing software used with the BIOPAC hardware should be used with great care:
    1. Be aware that when you view or make changes to a data file, AcqKnowledge immediately modifies the original! If the program crashes, it can corrupt the file. So always work with a copy of the data file, never the original.
    2. AcqKnowledge will open and close data files hundreds of times per second. This makes it unusable when working on files on network drives (W: at Brogden). Copy the file from the network drive to the PC's local (C:) drive before working with it. If you make any modifications, copy the modified version back to the network drive.
    3. Modifying a data file with AcqKnowledge may make it incompatible with the MATLAB import routines. Adding channels by processing existing ones or by synthesizing new ones will almost certainly cause this problem. You might want to talk to Larry before using AcqKnowledge in this way.
