Motor imagery of a lateralized sequential task is asymmetrically slowed in hemi-Parkinson's patients.
International audienceWe examined seven right-handed, asymmetrical (right side affected) Parkinson's disease patients and seven age-matched controls in a manual finger sequencing test using left and right hands in vision, no vision, and motor imagery conditions. All patients displayed motor asymmetry, favoring the left hand. They also displayed motor imagery asymmetry, mentally simulating movement more slowly with their right affected hand than with their left hand. Additionally, impairment in mental hand rotation correlated significantly with the imagery asymmetry. These data support two related hypotheses: (a) Motor sequence imagery and execution share common neural structures. (b) The frontostriatal system is among these shared structures

The mean power is plotted against variance explained for the number of SNPs the effect is spread over.
<p>As indicated, the total amount of variance explained, rather than the number of SNPs the effect is spread over, influences statistical power.</p
