Corticospinal Modulations during Bimanual Movement with Different Relative Phases
The purpose of this study was to investigate corticospinal modulation of bimanual (BM) movement with different relative phases (RPs). The participants rhythmically abducted and adducted the right index finger (unimanual (UM) movement) or both index fingers (BM movement) with a cyclic duration of 1 s. The RP of BM movement, defined as the time difference between one hand movement and the other h...
متن کاملShared bimanual tasks elicit bimanual reflexes during movement.
Previous research has suggested distinct predictive and reactive control mechanisms for bimanual movements compared with unimanual motion. Recent studies have extended these findings by demonstrating that movement corrections during bimanual movements might differ depending on whether or not the task is shared between the arms. We hypothesized that corrective responses during shared bimanual ta...
متن کاملGoal-selection and movement-related conflict during bimanual reaching movements.
Conflict during bimanual movements can arise during the selection of movement goals or during movement planning and execution. We demonstrate a behavioral and neural dissociation of these 2 types of conflict. During functional magnetic resonance imaging scanning, participants performed bimanual reaching movements with symmetric (congruent) or orthogonal (incongruent) trajectories. The required ...
متن کاملCorticospinal excitability modulation to hand muscles during movement imagery.
Motor evoked potentials (MEPs) to magnetic transcranial stimulation (TCS) were recorded from right abductor digiti minimi (ADM) and first dorsal interosseous (FDI) muscles, sharing the same peripheral innervation but engaged in two different motor demands. In seven healthy and trained subjects, the latencies, amplitudes and variability of MEPs were investigated under the following, randomly int...
متن کاملInfluence of reward on corticospinal excitability during movement preparation.
Current models of decision making postulate that action selection entails a competition within motor-related areas. According to this view, during action selection, motor activity should integrate cognitive information (e.g., reward) that drives our decisions. We tested this hypothesis in humans by measuring motor-evoked potentials (MEPs) in a left finger muscle during motor preparation in a ha...
