Novel MRI-compatible tactile stimulator for cortical mapping of foot sole pressure stimuli with fMRI
Magnetic Resonance in Medicine, 06/08/2012
Hao Y et al. – Gradient–recalled echo–planar images of seven healthy young adults using a typical block–designed 1 Hz sinusoidal stimulation protocol revealed significant activation contralaterally within the primary somatosensory cortex and paracentral gyrus, and bilaterally within the secondary somatosensory cortex. The stimulation system may therefore serve as a research tool to study functional brain networks involved in the perception and modulation of foot sole somatosensation and its relationship to motor control.
