SuperLab® Stimulus Presentation System
The STP100W SuperLab Stimulus Presentation System is a stand-alone system that measures subject responses to visual or auditory stimuli. It can present visual stimuli on a computer screen, or auditory stimuli via headphones or speakers, and simultaneously (1 ms resolution) send trigger signals to an MP System for data synchronization and collection purposes. The system includes an STP100D Isolated Digital Interface to connect to MP1X0 data acquisition systems.
The SuperLab software can be used to change the placement of visual stimuli on the screen, change the screen’s background color, choose from a variety of input and timing options, and provide feedback to subjects based on either response or reaction time. Different trigger channels can be paired to different visual or auditory stimuli to perform sophisticated evoked response averaging tests (e.g., P300).
Use the ‘Digital inputs to stim events‘ tool in AcqKnowledge to automatically score and label digital event marks from the SuperLab presentation. The digital channels are interpreted as a binary number. Each stimulus event placed into the graph has the corresponding number included with its label. This allows further analysis to distinguish between different types of stimulus events for automated event related analysis.

The synchronization signal(s) coming from the STP100W can be directed to an MP System running on a PC or Mac, but it’s not possible to run the STP100W on the same computer as the MP System. The STP100W requires that the SuperLab software and a Digital I/O card (PCI slot required) be placed on a PC running Windows 7/Vista/XP; Mac OS X setups require a StimTracker (STK100).
Learn a technique—Trans-radial Electrical Bioimpedance Velocimetry (TREV)—that is more user-friendly and less invasive than the transthoracic method. TREV measures blood movement in the radial and ulnar arteries of the forearm via bioimpedance.
Topics Covered:
– Presentation and discussion of TREV
– Derived Indices Relevant to TREV
– Hardware setup
– Participant setup
– Recognizing good quality and bad quality data
– Demonstration with the grip anticipation test
– Review of results from other tests
