Timing and control

Computers now play a dominant role in experimental control applications, but everyone knows that operating systems and video/audio hardware are unpredictable and unreliable to a degree.  You should not just assume that that stimuli appear when you want or expect them to, or that stimuli and triggers leave the experimental control computer at the same time.  Nor should you take the word of the software developer that there are no timing problems in his software.  Timing problems are often introduced by the operating system, the video or audio hardware or another device installed in the computer, meaning it is virtually impossible for the experimental control software developer to guarantee timing.  It is always best to test timing independently to be sure that events are occurring when they should.  We offer tools for measuring stimulus timing and a MATLAB-based hardware system for real-time stimulus control.

g.TRIGbox The g.TRIGbox is a device to generate ANALOG trigger pulses from various sensors or input signals. Input and output lines are isolated from each other. The trigger outputs can be connected to a data acquisition system (such as g.Recorder or g.MOBIlab+) or to the input sockets of g.USBamp biosignal amplifier. Thus, g.TRIGbox provides an exact detection and recording of almost any type of stimulation in your experimental paradigms.

StimTracker StimTracker was created with mainly one purpose in mind: sending DIGITAL event markers. And making it trivially easy to do so. So easy, in fact, that StimTracker is born ready to connect to a variety of EEG/ERP recording devices and a PC's parallel port. You no longer need to worry about incompatible connectors, pin assignments, and custom cables -- it's done for you.
