摘要

•We developed a pneumatic tactile stimulus delivery system (pTDS) for MR studies.•The pTDS enables the delivery of various types of tactile stimuli using tactile blocks.•An optical finger sensor allows for precise time detection of the tactile perception.•We demonstrated the feasibility of the pTDS in a human fMRI study.
