Bimanual Load-Lifting Task. A Model for the Study of Coordination Between Posture and Movement

The study of motor coordination has gained more and more interest over recent years. It is worthy of interest because in everyday life most of our movements are not restricted to a single joint but

Monitoring Coordination during Bimanual Movements: Where Is the Mastermind?

Direct insight is provided into the neural correlates of coordinated bimanual movements and the role of right STG is highlighted, which is more strongly activated in the coordination condition than the SMA, STG, or primary motor cortex.

Neuronal activity in the primate supplementary motor area and the primary motor cortex in relation to spatio-temporal bimanual coordination.

The results suggest that both the SMA and M1 may contribute to the control of sequential bimanual coordinated movements, but the contribution of other cortical and subcortical areas such as cingulate motor cortex and basal ganglia remains to be investigated.

The results imply that SMA may give rise normally to discharges informing the contralateral hemisphere of intended and/or ongoing movements via the corpus callosum, which may prevent duplication of responses during unimanual tasks and help to coordinate the behavior of both hands during a bimanual task.

Motor performance of stutterers: a search for mechanisms.

Results of research on bimanual coordination in stutterers are consistent with a model that attributes the interference, in part, to interhemispheric processes, possibly involving the supplementary motor area.

Neuronal Activity in the Supplementary, Presupplementary, and Premotor Cortex of Monkey

It is made a point that the neuronal activity in the three areas (the SMA, pre-SMA and PM) is different in association with sequential performance of multiple movements.



Bimanual coordination in monkeys.

Supplementary motor area in the monkey: activity of neurons during performance of a learned motor task.

The findings suggest that the discharges of a large number of neurons in SMA are changing during particular movements of either arm, and that only a small number of cells receive peripheral afferent sensory input.

The supplementary motor area of the cerebral cortex; a clinical and experimental study.

An analysis of observations on the properties of the superior and mesial intermediate precentral cortex in man and the patterns of focal seizures due to discharge in the area are presented, and an attempt is made to interpret the findings in terms of function.

The hindlimb representation of MII and the tail representation of MI appear to be considerably further rostral than depicted in the classical maps, which serves to resolve a discrepancy between the classical physiological and cytoarchitectonic maps for this region of cortex.
