Fig. 1 — Illustration of pneumatic stimulator used in the magnetoencephalographic (MEG) experiment ( ) and attached air line (—). In both tactile and tactile + movement conditions, stimuli were delivered at 25 psi for 30 ms to the 2nd digit of the right hand (RD2). During the tactile + movement condition, subjects curled their finger (flexion) prior to the administration of the tactile stimulus. To maintain constant position of the stimulator on the digit pad, surgical tape was used to secure the device to RD2.
