VIGALL: Vigilance Algorithm Leipzig 2.1

VIGALL Logo

The Vigilance Algorithm Leipzig (VIGALL) software allows objective classification of vigilance in resting EEG recordings, as well as in relation to stimuli in ERP paradigms. It is implemented as an Add-In for BrainVision Analyzer 2.1, developed by BrainProducts.

VIGALL was developed at the Department of Psychiatry of the University of Leipzig with support of the Leipzig Research Center for Civilisation Diseases (LIFE). The latest Version (VIGALL 2.1) was developed and validated at the Research Centre of the German Depression Foundation. It is freely available to all interested researchers from this web site.

 Installation instructions

  1. Make sure your installed version of BrainVision Analyzer 2.1 is up to date with the latest patches installed. VIGALL cannot be used by older versions of Analyzer 2.1 and will not appear in the AddIn menu in these.
  2. Download VIGALL and its manual.
  3. Copy VIGALL into your BrainVision Analyzer 2 folder (usually C:\Vision\Analyzer2\).
  4. Start BrainVision Analyzer 2, find VIGALL added to the Add Ins Tab in the menu.
    If it does not appear: Please make sure you're running the most recent version of Analyzer 2.1, i.e. check for any patches available from BrainProducts and install them if necessary. If your operating system automatically disables unregistered DLLs, you need to give permission to run in the context (right-click) menu of the DLL file. Depending on your operating system's settings, it may be necessary to run Analyzer as the same user who copied the DLL into the analyzer folder.
  5. Refer to the manual for all further instructions!

SEM Helper

A Microsoft Excel template with Visual Basic for Applications (VBA) macro can be found below. It supports the plausibility-check of stage 0-classification, as recommended in the VIGALL manual. By integrating context information into the classification, the VBA reclassifies stages 0 as stages B1 if they occur in close proximity of B2/3- or C-stages even in the absence of SEMs, as SEMs are characteristic but not imperative for drowsiness patterns.

 Research on VIGALL

Here we present a collection of articles about VIGALL and its applications. This page will be updated on a regular basis. Currently, several other studies on VIGALL are under review. These, for example, investigate arousal regulation in manic versus depressive episodes, arousal regulation as treatment response predictor, or evoked potentials during different states of brain arousal.

We would be happy to also put VIGALL studies of other working groups on this page. Please do not hesitate to contact us.
