fMRI study of bimanual coordination.
Eleven right-handed subjects performed uni- and bimanual tapping tasks. Hemodynamic responses as measured with functional magnetic resonance imaging (fMRI) in the primary somato-motor cortex (SMC) showed that during bimanual activity the SMC contralateral to the hand taking the faster rate was more strongly activated than the SMC contralateral to hand taking the slower rate. There were no asymm...
متن کاملDimensionality in rhythmic bimanual coordination.
Newell and Vaillancourt (2001) hypothesized that the dimensionality of motor behavior is a function of the level of task performance and the task dynamic. The present study examined high (in-phase), moderate (antiphase) and low (45°, 90°, and 135° relative phase) levels of task performance in bimanual coordination. Estimates of dimensionality were calculated for the component (effector movement...
متن کاملDistant functional connectivity for bimanual finger coordination declines with aging: an fMRI and SEM exploration
Although bimanual finger coordination is known to decline with aging, it still remains unclear how exactly the neural substrates underlying the coordination differ between young and elderly adults. The present study focused on: (1) characterization of the functional connectivity within the motor association cortex which is required for successful bimanual finger coordination, and (2) to elucida...
متن کاملBimanual coordination: influence of age and gender.
INTRODUCTION Bimanual hand coordination is very important in carrying out day to day activities like buttoning the shirt, driving, picking up objects. It depends on various factors like age, gender, education, intactness of central and peripheral nervous system, Occupation and lifestyle. AIM The aim of the study was to compare the efficiency of bimanual hand coordination between right handed ...
