MRI-compatible response collection system for fMRI experiments.


  • Participant response in fMRI experiments.


  • The system consists of two grips, an interface unit, and fiberoptic cables.
  • Ergonomic design with four buttons (trigger finger and thumb for L & R hands).
  • Standard TTL output compatible with most stimulus presentation programs.
  • 100% fiber-optic.
  • Participant response can be monitored by light and optional sound signaling.


The response grips were purchased from Nordic Neuro Lab. A second set of response grips is also available for development and training purposes in SLEIC's mock scanner room.
