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.

Differential roles of neuronal activity in the supplementary and presupplementary motor areas: from information retrieval to motor planning and execution.

We explored functional differences between the supplementary and presupplementary motor areas (SMA and pre-SMA, respectively) systematically with respect to multiple behavioral factors, ranging from

The role of the Supplementary Motor Area during internally and externally triggered movement sequences: a TMS study.

The hypothesis that the experimental group showed a slowed performance compared to the control group during familiar and single-stimulus test phases could not be confirmed, but the SMA seems to play a key role in the preparation of sequences performed in the chunking mode, especially sequences that only provide the first stimulus.

Comparison of neuronal activity in the rostral supplementary and cingulate motor areas during a task with cognitive and motor demands

The results suggest that although the two areas share functional properties, they also participate in different aspects of motor behaviour, which give them the potential to integrate external stimuli and internal states during motor planning.

Neuronal activity in the supplementary motor area of monkeys adapting to a new dynamic environment.

It is shown that neurons in SMA reflect the movement dynamics individually and as a population, and that their activity undergoes a variety of plastic changes when monkeys adapt to a new dynamic environment.

FMRI Studies of the Supplementary Motor Area and the Premotor Cortex

Functional maps resulting from comparison of the motor tasks with REST reveal activation in primary sensorimotor cortex, medial and lateral premotor areas, cingulate cortex, and parietal cortex, reflecting the functional heterogeneity of these areas suggested by previous studies.

Activation of the supplementary motor area (SMA) during performance of visually guided movements.

The 2-deoxyglucose (2DG) technique was used to measure functional activation in the motor areas on the medial wall of the hemisphere in monkeys trained to perform visually guided reaching movements to randomly presented targets and found that the SMA was strongly activated during reaching to different visual targets.

Do bimanual motor actions involve the dorsal premotor (PMd), cingulate (CMA) and posterior parietal (PPC) cortices? Comparison with primary and supplementary motor cortical areas

The results suggest that the five cortical areas PMd, CMA, PPC, SMA and M1 are participating to the control of sequential bimanually coordinated movements.

Neuronal activity in medial frontal cortex during learning of sequential procedures.

The results suggest that the pre-SMA, rather than SMA, is more involved in the acquisition of new sequential procedures.

Skill representation in the primary motor cortex after long-term practice.

M1 may be a site of storage for the internal representation of skilled sequential movements, especially sequences of movements, during skilled movement sequences in macaques trained to successively hit targets on a monitor.

Neuronal activity in the primate premotor, supplementary, and precentral motor cortex during visually guided and internally determined sequential movements.

Observations support a hypothesis that the SMA is more related to IT, whereas PM is more involved in VT, and some indications pointing to a functional subdivision of PM are obtained.

Preparation for movement: neural representations of intended direction in three motor areas of the monkey.

Compared the functional properties of neurons in three interrelated motor areas that have been implicated in the planning and execution of visually guided limb movements, the majority of cells with task-related preparatory activity showed selective activation in anticipation of elbow movements in a particular direction.

A motor area rostral to the supplementary motor area (presupplementary motor area) in the monkey: neuronal activity during a learned motor task.

Directional selectivity was found in all the cue, preparatory, and movement-related responses in the supplementary motor area and the rostral part of macaque monkey.

Preferential activity of dentate neurons during limb movements guided by vision.

It is suggested that a portion of the dentate nucleus is preferentially involved in the generation and/or guidance of movement based on visual cues.

The role of premotor cortex and the supplementary motor area in the temporal control of movement in man.

It was found that patients with left SMA lesions had an increase in reaction time on a sequential digit task when sequences had to be produced under delayed conditions and the controls showed a decrease of reaction time after previous stimulus presentation.

Visual tracking and neuron activity in the post-arcuate area in monkeys.

A suggestion was made that in the FB area, after receiving the visual cue information, a function for the later movement direction and initiation are produced and sent to the motor apparatus within the brain so that effective tracking task can be performed.

Premotor cortex and conditional motor learning in man.

Patients with PMC lesions were only impaired when they had to recall a movement from memory on the basis of a sensory cue, but not for an association involving spatial location, which indicates that the PMC plays a role in sensory conditional motor learning.
