Electroencephalography (EEG) System
MINDSET has a 128-channel BioSemi ActiveTwo electrophysiology system for recording high-density EEG during the performance of cognitive tasks (www.biosemi.com). Electrode caps for four different head sizes are maintained with the system. Acquisition computers use BioSemi software to record EEG data and all stimulus and behavioral response codes for later analysis. Software from Neurobehavioral Systems is available for precise presentation of visual and auditory stimuli and online monitoring of behavioral performance. The event-related potential software system ERPSS (courtesy of Steve Hillyard, UCSD, San Diego, CA) and EEGLab (courtesy of the Swartz Center for Computational Neuroscience, UCSD, San Diego, CA) are available for analysis of the EEG data. MRN also has the capability for concurrent EEG/fMRI using the BrainAmp MR system from brain products and concurrent EEG/MEG using the Neuromag EEG System.
