The purpose of this study was to compare lateralized cerebral activations elicited during
self-initiated movement mirroring and observation of movements. SUBJECTS: A total
of 15 right-handed healthy subjects, age range 22-56 years. METHODS: Functional
imaging study comparing movement mirroring with movement observation, in both
hands, in an otherwise identical setting. Imaging data were analysed using
statistical parametric mapping software, with significance threshold set at p <
0.01 (false discovery rate) and a minimum cluster size of 20 voxels. RESULTS:
Movement mirroring induced additional activation in primary and higher-order
visual areas strictly contralateral to the limb seen by the subject. There was no
significant difference of brain activity when comparing movement observation of
somebody else's right hand with left hand. CONCLUSION: Lateralized cerebral
activations are elicited by inversion of visual feedback (movement mirroring), but not by movement observation.
