PST has engineered the new Celeritas Fiber Optic Response System to accurately gather participant responses and verify signals.
The new system can be customized to fit your research needs by selecting the combination of Button Response Units (BRUs) and Joysticks. The BRUs and Joysticks comfortably fit small to large hand sizes and are constructed entirely of non-metallic components - completely eliminating all metal inside the magnet room. The units communicate button presses through fiber optic cabling which connects to an Interface Console located in the control room through an available wave guide.
The Interface Console provides real-time feedback of participant responses via LED indicators and includes a set of buttons to make responses for the participant as needed. The system seamlessly integrates with E-Prime® through a USB connection. The new Interface Console comes with an Optical Connector and a BNC Connector. These connectors allow the computer to accept either an optical or an electrical TTL pulse that the stimulus presentation computer interprets as another button press, allowing the user to synchronize their experiments with the MR scanner.
The BRUs and Joysticks are assembled using chemical resistant, medical grade, biocompatible plastic. The chemical resistance allows for repeated cleaning without degradation of the material or color. The new BRUs include a tactile indicator to ensure correct finger placement during experiments. The new BRUs also give you the ability to adjust the wrist sled for a more comfortable fit.

Q: Can I test an experiment from the control room of an MRI center?
A: Yes. You can test an experiment using the BRU console from the control room without having to go into the magnet room.
Q: Will I know if the study participant has fallen asleep or is not performing the task correctly?
A: Yes. The BRU console has an LED indicator for each button on the response units. You will be able to determine how the participant is responding at all times.
