In order to expand the repertoire of somatosensory functions that can be effectively studied through functional MRI, we have developed a tactile stimulator which can deliver rich and varied combinations of stimulation that simulate natural tactile exploration. The system is computer controlled and compatible with an MRI environment. Complex aspects of somesthesis can thus be studied independent of confounds introduced by motor activity or problems with precision, accuracy or reproducibility of stimulus delivery.
为了扩大通过功能磁共振成像（fMRI）能够有效研究的体感功能范围，我们开发了一种触觉刺激器，它可以提供丰富多样的刺激组合，模拟自然的触觉探索。该系统由计算机控制，并且与磁共振成像环境兼容。因此，可以独立于运动活动引入的混杂因素或刺激传递的精度、准确性或可重复性问题，来研究本体感觉的复杂方面。
