Introduction The Evoked Potential option allows to the doctor to perform wide range of auditory and cognitive tests in his ERP studies. This add-on includes also all features for clinical use as well as advanced qEEG analysis. With Evoked Potential option combined to HBI database of healthy subjects your system becomes a power tool for diagnostics. ERP analysis Our analysis software included a lot of possibilities for advanced ERP analysis. EP analysis include Event-Related Potentials and Event-related De/Synchronization computation, Wavelet power and coherence analysis, ERP Independent component analysis and Task performance (omission and commission errors, reaction time and its variance) calculation. Data averaging and comparison of analysis results allow the doctor to perform pre- and post as well as different patients comparison. Available tests We have a number of world recognized long-latency ERP testes included in default list. Now following test types are available for the doctor: P300, MMN, CNV as well different Pattern tests. Stimuli presentation Stimuli are presented on the second monitor attached to the doctor computer. This new dual monitor mode makes ERP investigation very easy in setup and recording. And our ERP calibration procedure allow you to avoid any delays in stimuli presentation.
