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 also 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.
