Precise stimulus presentation
STIM2 is Compumedics Neuroscan’s stimulus presentation and experimental design system. Operating under Windows, STIM2 provides a familiar and simple interface to design and deliver stimuli with ease and, more importantly, accuracy. STIM2 provides complete control of the experiment, while delivering the highest quality stimuli.
STIM2 is a complete software environment for custom stimulus and task design as well as presentation. The STIM2 system can be integrated in fMRI, MEG, and other functional neuro-imaging applications. The software provides a familiar menu-driven interface in which to design and present visual and auditory stimulation paradigms.
STIM2’s powerful and intuitive design translates into a short learning curve and quick implementation. The modules make it easy to design and execute your stimuli with the greatest precision, and the wide array of pre-packaged stimuli ensures fast integration into your research.
STIM2 is fully integrated with the Cedrus StimTracker. This system uses photocells and auditory threshold detection to identify stimulus onset with the greatest accuracy possible.
STIM2 is comprised of 14 modules including a generic programmable experiment control module (Gentask), a sound file editor, and an image file converter. Other modules are categorized into Motor, Perceptual, Attention, Memory, and Cognitive functions, many of which have neuropsychological parallels (Tapping, Stroop, Categories, Card Sorting, etc.). The Gentask program includes an interface for creating and presenting almost any type of visual, auditory, or combined task and recording behavioral responses. Gentask has been used for a variety of experiments including auditory P300, N400, MMN, CNV, picture memory, and many more. The Gentask Editor makes creating, modifying and debugging sequences files very easy. The Sound Editor program is used for recording, editing, and presenting digital sound segments. The Image Converter module will convert less familiar formats into commonly encountered types of graphics files (BMP, JPG, PNG, TIF, etc.) that can then be presented.
STIM2 interfaces seamlessly with CURRY 7 and SCAN, as well as any of our amplifiers: SynAmps RT, Neuvo, NuAmps and Grael.
