Stim²is the next evolutionary step in stimulus presentation and experimental design. Running within the Windows XP (only) environment, Stim² retains the functionality and timing of the original DOS-based STIM, but with a contemporary user interface and numerous expanded features.

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.

Stim²is comprised of 14 task modules, a generic programmable module (Gentask), a sound file editor, and an image file converter. The task modules may be categorized into Motor, Perceptual, Attention, Memory, and Cognitive tasks, many of which have neuropsychological similarity (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 much easier. TheSound 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.

There are two versions of Stim²: Stim² Complete, which uses specially designed hardware, and a Software Only version that uses the hardware in the computer. The Complete system includes the 4-button STIM Response Pad, software/hardware control of the decibel levels (precise dB levels), and the STIM microphone. Keyboard and mouse responses are available with both systems; the STIM Response Pad provides the most accurately timed responses. The Software Only version may be adequate for some situations; however, the Complete system is generally preferred. It has additional flexibility and control, and it is likely that long range development will favor the Complete system.

Stim² interfaces seamlessly with CURRY 7 and SCAN, as well as any of our amplifiers: SynAmps², SynAmps RT, or NuAmps.
