An MR-compatible vibrotactile stimulator using a planar-coil-type actuator was developed for generating vibrations at the target frequency.34 The planar-coil-type actuator consisted of electric wires in a planar coil form and generated vibrations within a static magnetic field of a magnetic resonance (MR) scanner. Stimulus parameters, including the vibration frequency (250 Hz), were controlled with E-Prime software (Psychology Software Tools, Inc. Sharpsburg, PA, USA) and synchronized by a trigger signal sent through a parallel port. Each stimulator weighed 11 g and had a contact surface area of 1 × 1 cm2.
