Sometimes, reliable laboratory procedures are facilitated by restricting operator interventions. This is why BrainVision Recorder allows the administrator to tailor and restrict operator permissions for standard users. This includes granting permission to create, edit, or select a workspace, to edit Preferences and to edit Amplifier-specific Settings (see Figure 1). To alter these settings, go to Configuration > Administrator.
On the other hand, for a lab manager who may need to switch between the different amplifiers and who uses Recorder’s full functionality, it may be easier to run Recorder with administrator privileges. To do this automatically, right-click on the Recorder icon on your desktop and choose Properties. Then, select the tab Compatibility and choose Run this program as an administrator (see Figure 2). Finally, click on OK. Here you go!
Visualization requirements of peripheral physiological signals differ significantly from EEG signals as time scale and amplitude range might be completely different. Using BrainVision Recorder’s “scientific view”, you will be able to adjust time- and amplitude-scaling for each peripheral physiological signal.
Once you start monitoring, you can activate the scientific view by right-clicking on the channel name and selecting Display this channel in a new tab from the context menu (see Figure 3). The appropriate visualization enables you to judge signal quality, detect if the sensor was moved and correct problems during run time.
Cognitive neuroscientists tend to have preferences for how to visualize their data. Montages allow you to optimize the way your data is presented in BrainVision Recorder and tailor visualization to your specific needs. If you wish to monitor only a subset of channels, rearrange their sequence, or assign a new reference channel – that’s what Montages are for! If a montage is activated in monitoring or recording mode, only the channels assigned to it will be displayed. Note that montages affect only the visualization while the original (recorded) data remain unchanged.
To create a new montage, select Display Montage > New from the menu and choose one of three reference types (Original, Average, Bipolar; see Figure 4). In the Edit dialogue, assign channels to the montage by manually entering their names or selecting them from the dropdown list. Once you’re finished, save the new montage under any chosen name (e.g., Original1.mont). To display a montage, call it from the Display Montage menu or via a simple keyboard shortcut. In Display Montage > Options up to nine keyboard shortcuts can be assigned that allow you to quickly switch between multiple montages (see Figure 5).
