“…Components of these MRPs are, for example, the Bereitschaftspotential or readiness potential, the premotion positivity, and the motor potential (see, e.g., Kornhuber & Deecke, 1965;Kristeva, Cheyne, Lang, Lindengen, & Deecke, 1990). Negative potentials are also present during the movement (movement monitoring potential, or MMP; Foit, Grozinger, & Kornhuber, 1982;Gru¨newald-Zuberbier & Gru¨newald, 1978) and seem to be enhanced by higher task complexity (Niemann, Winker, Hufschmidt, & Lucking, 1994), increasing force level, and especially higher rate of force development (Slobounov, Johnston, Chiang, & Ray, 2002;Slobounov, Ray, & Simon, 1998). These findings strongly suggest that this negative potential does not just reflect motor activity itself, but a monitoring process of these activities.…”

Action monitoring in motor control: ERPs following selection and execution errors in a force production task

et al. 2003

Action monitoring has been studied in many tasks by means of measuring the error-related negativity (Ne/ERN), but never in a motor control task requiring precise force production. Errors in discrete choice reaction tasks are the result of incorrect selections, but errors in force production can also arise from incorrect executions. ERPs were obtained while participants produced low or high isometric forces with their left or right hand. As expected, incorrect choices of hand elicited an Ne/ERN. Interestingly, Ne/ERNs were also present in the less discrete selection error of an incorrect choice of force, but only when erroneously a low instead of a high force was chosen. In both force ranges, no Ne/ERNs were found after errors in execution. These errors showed a large positivity in feedback ERPs and, similar to correct responses, a prolonged negativity in response ERPs. We propose that, compared to selection errors, the time uncertainty aspects of execution errors and the resulting changing response representations prohibit error detection by the internal monitoring system responsible for generating the Ne/ERN.

“…Electrocortical events accompanying movement are seen in a variety of studies~e.g., Cooper, McCallum, & Cornthwaite, 1989;Lang et al, 1988;Lang, Zilch, Koska, Lindinger, & Deecke, 1989, Niemann, Winker, Hufschmidt, & Lucking, 1994!. One finding is that performance-related DC shifts are useful for differentiating simple and complex motor tasks~Lang et al, 1989!.…”

Movement‐related potentials accompanying unilateral finger movements with special reference to rate of force development

1998

The aim of this study was to examine the relationship between force and rate of force development with electroencephalogram correlates. The primary question was whether the different components of movement related potentials (MRPs) were related to specific properties of force output while subjects performed index finger force production tasks. The peak force and rate of force development (e.g., a product of peak force over time-to-peak force) were manipulated, and the effects of these manipulations on components of MRPs preceding and accompanying force production tasks were examined. The hypothesis was that the rate of force development, rather than level of force itself, would directly influence the later component of MRPs. Consistent with this hypothesis was the finding that the amplitudes of MRP components preceding (MP) and accompanying (MMP, MTP) finger force production movements were significantly correlated with force development rate.

In a number of recent studies, the specific sensitivity of movement-related EEG potentials toward experimental manipulations of motor tasks using the index finger as a primary end-effector is well documented. The major question in this study was whether different movement-related EEG components are primarily end-effector or task dependent. Accordingly, the experimental task (i.e., the rate of force development - a ratio of peak force to time-to-peak force) was systematically manipulated and the effects of this manipulation on movement-related potentials were examined while subjects used either the index, middle, ring or little finger. Significant effects observed in this study were due mainly to the sensitivity of movement-related potentials preceding movement onset (Bereit shafts potential and motor potential) toward the specific finger performing the task and the sensitivity of components accompanying the task (movement-monitoring potential) toward the rate of force development. In addition, both movement-related potentials preceding and accompanying movement significantly changed as a function of the finger performing the slow task (lower rate of force development) with maximum values observed for the ring finger and minimal values observed for the index finger. Behaviorally subjects were less accurate during slow tasks regardless of the finger performing the task. In contrast, the amplitude of neither early nor late components of movement-related potentials changed as a function of the finger performing the fast task (higher rate of force development). Overall, our results are consistent with the notion that the whole complex of movement-related EEG potentials reflect a combination of factors including the selection of corresponding general motor programs as reflected in the amplitude of potentials preceding movement and specific elements of the task including rate of force development as reflected in the amplitude of potentials accompanying movement execution.
