Current Source Density (CSD) in WinEEG

Current source density analysis (CSD) is a class of methods of analysis of extracellular electric potentials recorded at multiple sites leading to estimates of current sources generating the measured potentials. CSD Montage in WinEEG is based on spherical spline algorithm (Perrin et al., 1989) to compute scalp surface Laplacian or Current Source Density estimates for surface potentials (EEG/ERP). To create "CSD montage" you need to follow following steps: Go to Montage parameters and select AvW=CSD by F.Perrin option for [...]

WinHRV quick start guide

1. Import EEG file containing ECG date. WinHRV-File-Import Data… Select the bio (poly) cahnnel that was used to record ECG data from the drop down menu. 2. Select the ECG interval you would like to process. We suggest to select it not from the beginning of the file, like shown on the screen capture. Click on Analysis – Process ECG to process the file and mark the R picks automatically. 3. You can delete to add R picks manual by clicking [...]

How to make Spike review in WinEEG

WinEEG offers tools for spike detection, averaging and localization in Loreta. 1. To detect and mark spikes to go Analysis – Spike Detection… Software will search for Spikes according to the template. We do not recommend to change template parameters except of Sharpness. 2. All detected Spikes will be marked in EEG windows including channel name there the Spike was detected. 3. Right mouse click on Spike to change channel name or delete it 4. To add new Spike manually [...]

Independent components (ICA) of ERPs

These independent components of ERP linearly mixed will comprise the original averaged ERP signal. Each component is an independent piece of the ERP signal, representing a stage in the processing of the perception and then the motor aspects and then the cingulate’s self monitoring of the response. Though inter-related, each piece is a separate stage in the sequential process that creates the complexity of the ERP itself. In WInEEG software we apply Infomax ICA algorithm to decompose original ERP into [...]

How to disable driver signature on Windows 10?

Sometimes to install driver for old Mitsar-EEG units you have to disable drivers signature on your Window 10 machine. This is the simplest way to disable driver signature enforcement on Windows 10, but bear in mind that this method will only disable driver signature temporarily. After you restart your computer driver signature enforcement will automatically turn itself on. To disable driver signature enforcement do the following: Click on Start menu -> Settings -> Update & Security -> Recovery. Then Click on [...]
