A Full Range of Research Stimulation Solutions

Whether your research requires a complete VR/Immersive solution with accompanying Physiology Data, Isolated stimulus hardware, a leading stimulus presentation package, or stroboscopes to synchronize or trigger your BIOPAC data acquisition and analysis system, or olfactory, haptic, visual or auditory stimulation, BIOPAC provides a solution to fit your experiment’s needs. BIOPAC’s Virtual Reality (VR) solutions provide a full range of cost-effective virtual reality systems, while BIOPAC also offers leading stimulus presentation software and hardware such as SuperLab, StimTracker, or E-Prime. When used in combination with BIOPAC electrodes, amplifiers, and MP Research Systems with AcqKnowledge software, these solutions are part of a complete data acquisition and analysis system supporting experiments in which stimulation of subjects is a key component.

Stimulation options for:

  • Constant Current
  • Constant Voltage
  • Visual
  • Auditory
  • Haptic
  • Olfactory
  • Virtual Reality
