摘要: Object. Functional magnetic resonance (fMR) imaging was used to determine patterns of cerebral blood flow changes in the somatosensory cortex that result from median nerve stimulation (MNS). Methods. Ten healthy volunteers underwent right at frequencies 5.1 Hz (five volunteers) and 50 volunteers). The left stimulated (two Tactile (with a soft brush) index finger also applied (three MR data were transformed into Talairach space coordinates averaged by group. Results showed significant activation (p 0.05) between v...
