Control of motor performance during fMRI tasks. Left top: three possibilities to control hand motor activity: pneumatic ball, coupled with a pressure measurement device; glove, commercially distributed for virtual reality environments and suitable for MRI; finger sequence control keyboard. Right top: development with an individual splint for controlling occlusal pressure and frequency (see plot middle right) with the Varioport device (Varioport; Stuttgart; middle left). Bottom: control of swallowing by a pressure cushion combined with the Varioport device. Skin conductance response (SCR) can be measured with Brain Vision Analyzer 2.0 (Brain Products, Gilching, Germany; bottom right).
