摘要: To investigate the mechanism of mirror movements seen in X-linked Kallmann's syndrome, we measured changes regional cerebral blood flow with H2 15O-PET. We studied six right-handed Kallmann male subjects and matched, control during an externally paced finger opposition task. The analyses were done both on a single subject group basis. showed strong primary motor cortex (M1) activation contralateral to voluntarily moved hand, but there was also significant degree M1 ipsilateral i.e. mirroring hand. However, when comparing activation, hand significantly stronger. In controls, increases rCBF voluntary movement either hand; small found two out normal they their left second experiment it shown that, subjects, passive right resulted that similar made This suggests, does not prove, may be due sensory feedback from involuntarily
