PST has engineered the Fiber Optic Button Response System to accurately gather participant responses and verify signals.
The Fiber Optic Button Response Units attach to the participant’s wrists and can be comfortably adjusted during scanning. The units are constructed almost entirely from plastic, completely eliminating all metal inside the magnet room. The units communicate button presses through fiber optic cabling which connects to a Fiber Optic Interface Console located in the control room through an available wave guide.
The Fiber Optic Interface Console provides real-time feedback of participant responses via LED indicators and includes a set of switches which can be used to make responses for the participant as needed. The system seamlessly integrates with E-Prime® through a serial connection and other software packages through a USB connection. TTL output signals can be used to interface with other data collection devices and software. The interface console comes with a BNC Connector that allows the computer to accept a TTL Pulse that the stimulus presentation computer interprets as another button press, allowing the user to synchronize their experiments with the MR scanner.
The new Celeritas™ Series response units are assembled using high-impact, chemical resistant, medical grade plastic. The chemical resistance allows for repeated cleaning without degradation of the material or color. The new Celeritas Series response units include a tactile indicator to ensure correct finger placement during experiments. The new units 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.
