WinEEG advanced version allows the user all of the functions of the basic version and additionally the ability to import non-Mitsar format files, record Evented Related Potential data (with the use of PsyTask), and to perform database comparisons (with the addition of the HBI database).
WinEEG is included with Mitsar-202 amplifiers and can be added to the purchase of Mitsar-201 amplifiers for an additional fee.
The EEG (up to 32 channels) is stored on the hard disk and available for subsequent analysis. During recording, the signals are continuously displayed on the screen. EEG can be recorded synchronously with visual and acoustic stimuli presentation for ERP/ERD studies*.
ERPs and ERDs are computed in psychological tasks of various designs. The task design is performed by Psytask* or by the conventional Presentation software (Presentation, E-Prime). During EEG recording photoflash* may be controlled manually or using predefined program. Automatic impedance measurement procedure helps to control a quality of electrodes setting.
A flexible review program allows fast display of the EEG on the computer monitor and immediate access to any part of the recording. Ten user definable labels may be used to mark EEG recordings for future quick access to this part.
Recorded EEG can be displayed in different montages: monopolar, bipolar, average reference, weighted average reference and etc. EEG can be filtered by IIR digital filters to change frequency band of recording to and eliminate environmental noise (50 or 60 Hz). Also EEG can be filtered by high order FIR filters.
WinEEG software includes the multichannel spectral analysis, brain mapping and coherence. Power spectra and coherence can be computed for any selected part of recorded EEG. Different parameters of spectra computed for predefined frequency band ranges can be displayed as histograms, maps and tables.
The spectra data can be exported to other applications (standard statistical packages such as STATISTICA* or SPSS* ) by using ASCII format for a future statistical analysis.
