EEG Data Acquisition
BIOPAC offers a
wide range of tools for recording and analyzing human or animal EEG signals.
Available hardware includes the EEG100C amplifier, which amplifies bioelectric
potentials associated with neuronal activity of the brain and can be used to
perform unipolar or bipolar EEG measurements. The amplifier output can be
switched between normal EEG and alpha wave detection. The 0.005 Hz HP
setting will support Slow Cortical Potential measurement in the EEG. The
Alpha detection mode outputs a smoothed wave with a peak indicating maximal
alpha activity (signal energy in the 8-13 Hz frequency range).
EEG can now
also be recorded from an MRI using the EEG100C-MRI smart amplifier. Data
recording is easier and final results are cleaner when using the smart
amplifier to derive EEG signals during fMRI or MRI. The unit incorporates
advance signal processing to remove spurious MRI artifacts from physiological
data. The MRI version of the EEG100C can still be sampled at the same rate as
the normal amplifier during recording. This is because the MRI related
artifacts are removed from the source, thus still leaving a perfectly recorded
EEG signal.
The amplifier
includes a number of helpful features that improve derived EEG signals. There
is less sensitivity to electrode and transducer lead placement and improved
gain selectability. The unit minimizes computer based real-time or
post-processing signal processing for faster data analysis. Cleaner data is
available as a real-time analog output for easy analysis. The EEG100C-MRI
contains the same functionality as the normal amplifier with the added
compatibility with MRI cable and filter sets.
AcqKnowledge
provides powerful EEG analysis solutions. Use AcqKnowledge software to
automatically filter raw EEG signal for Alpha, Beta, Theta, and Gamma wave
activity and provide full frequency analysis of the data. AcqKnowledge
contains powerful EEG analysis that provides a fully automated, epoch driven,
analysis of the signal. The software also will remove any EOG artifacts from
the signals.
BIOPAC also
offers a suite of wireless EEG solutions for mobile data recording. The Mobita,
BioNomadix, and B-Alert X10 units all provide powerful wireless recording
alternatives for EEG. The hardware allows for recording of EEG ranging from a
single channel to up to 32 channels of data. Combined with AcqKnowledge
software, the BIOPAC range of EEG recording products encompasses any need for
in-lab recording, real-world and MRI applications. Learn more at EEG
