The Celeritas button response units all work with the same control console and can be quickly changed to meet each study’s needs. The button units are custom molded to fit the ergonomics of a person laying down in the scanner to ensure they are able to comfortably respond during long scan sessions. All button units have included wrist straps in case the response units are released in the scanner. The button units comfortably fit small to large hand sizes and are constructed entirely of non-metallic components – completely eliminating all metal inside the magnet room.
USB versions of our response units are perfect for practicing a task, perhaps in an MRI Simulator, prior to performing the task in the scanner. Celeritas USB response units are available for the following all BRU models. The USB units connect directly to the PC running the experiment and appear as a keyboard device.
The Celeritas Console includes both BNC and Optical connections to allow for conversion of the trigger pulse provided by the scanner into an easy-to-work-with keyboard button press. This feature allows for the synchronization of the scanner with the stimulus presentation software (E-Prime/MATLAB/etc.). The Celeritas system is able to provide millisecond-accurate responses when working with E-Prime.
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 BRUs include a tactile indicator to ensure correct finger placement during experiments. The wrist sleds are adjustable for a more comfortable fit.
The Celeritas Fiber Optic Response System can be customized with the following components:
- Interface Console
- Celeritas Monitor Software
- Fiber Optic Button Response Units – two, three, or five-button (includes 4-meter cable)
- USB Response Units – two, three, or five-button (includes USB cable to connect to computer)
- Joysticks with omnidirectional analog stick and four buttonsĀ (include 4-meters of cable)
- 10, 20, or 30 meter fiber cables
