The training of performance skills is very important in piano learning and performance, which directly determines the quality effect performer. As a multi-voice instrument, requires joint control left right hands to obtain ideal effect. In this regard, performer should improve attention hand training, show beautiful moving performance. Based on this, paper briefly describes importance analyzes ...

Handedness and eye-dominance are undoubtedly associated statistically, although a previous meta-analysis has found that the precise relationship is difficult to explain, with about 35% of right-handers and 57% of left-handers being left eye dominant. Of particular difficulty to genetic or other models is that the proportions are distributed asymmetrically around 50%. The present study asked whe...

Asymmetries in the kinematics and neural substrates of voluntary right and left eye-hand coordinated movements have been accredited to differential hemispheric specialization. An alternative explanation for between-hand movement differences could result from hand preference related effects. To test both assumptions, an experiment was conducted with left- and right-handers performing goal-direct...

abstract. let r be a 2-torsion free ring with identity. in this paper, first we prove that any jordan left derivation (hence, any left derivation) on the full matrix ringmn(r) (n  2) is identically zero, and any generalized left derivation on this ring is a right centralizer. next, we show that if r is also a prime ring and n  1, then any jordan left derivation on the ring tn(r) of all n×n up...

A patient with MRI confirmed lesions in the corpus callosum and the left cingulate gyrus had a rare syndrome of crossed avoiding reaction of the left hand. With the right hand she could reach a stimulus object in whatever space it was presented. With the left hand, however, she could not mobilise it to reach a stimulus presented in the right hemispace relative to her body axis. In the left hemi...
