title: [Storing of spatial order of targets during reproduction of movement sequence: the role of the right hand].
abstract: Acquisition of sequences of movements performed with the right and the left hands was studied for three types of positions of their elementary targets: 1) random position; 2) simple rule--diagonal sequence of targets with a single trajectory change by 90 deg.; 3) complicated rule--with the sequence of targets as for simple rule, but randomized order of presentation of targets. It is shown that the information about the location of targets according to the complicated rule is used during movements performed with the right but not left hand. It is suggested that the observed phenomenon is connected with the localization of the spatial sequence acquisition mechanisms in the left brain hemisphere. This type of information coding may underlie the mechanisms of gesture and speech control.
