Title:
A new device for tactile stimulation during fMRI. 
Abstract:
Standardized somatosensory stimulation of the face during functional MRI is technically demanding due to the high magnetic field of the MRI scanner and the confined geometry of the head coil. We developed a new computer-controlled MR-compatible stimulation device for mapping somatosensory-evoked brain activations during fMRI. The device employs von Frey-filaments which are commonly used for quantitative sensory testing (QST) to deliver punctate tactile stimuli to the face and other body surfaces...    »
