“…This point is further supported by a study that examined alternating and equal intervals of either force or time. Pope and colleagues (2005) examined a task that required subjects to produce force pulses during four conditions that had: 1) equal temporal intervals and equal force, 2) alternating intervals and equal force, 3) equal intervals and alternating force, and 4) alternating intervals and alternating force. The condition that resulted in the greatest activity in the putamen was the condition that required alternating force, rather than alternating temporal intervals.…”

“…Using fMRI to examine activation in the basal ganglia, the authors found that the anterior basal ganglia nuclei showed increased activation related to the selection component of the task whereas activation in posterior basal ganglia nuclei was related to dynamic force pulse production. Pope and colleagues (2005) used a slightly different force production task and also found a specific role for anterior basal ganglia nuclei in planning and switching aspects of force control. It remains unclear however if anterior basal ganglia nuclei, which include the caudate and anterior putamen, have a role in the prediction of grip force output.…”

Predicting grip force amplitude involves circuits in the anterior basal ganglia

The ability to grip objects allows us to perform many activities of daily living such as eating and drinking. Lesions to and disorders of the basal ganglia can cause deficits in grip force control. Although the prediction of grip force amplitude is an important component of performing a grip force task, the extant literature suggests that this process may not include the basal ganglia. This study used functional magnetic resonance imaging (fMRI) to explore the functional brain mechanisms underlying the prediction of grip force amplitude. The mean force and duration of force did not vary across prediction levels. As anticipated, the reaction time decreased with the level of grip force predictions. In confirmation of previous studies, the parieto-frontal and cerebellar circuits increased their fMRI signal as grip force predictability increased. In addition, the novel finding was that anterior nuclei in the basal ganglia such as caudate and anterior putamen also had an fMRI signal that increased with the level of grip force prediction. In contrast, the fMRI signal in posterior nuclei of the basal ganglia did not change with the level of prediction. These findings provide new evidence indicating that anterior basal ganglia nuclei are involved in the predictive scaling of precision grip force control. Further, the results provide additional support for the planning and parameterization model of the basal ganglia by demonstrating than specific anterior nuclei of the basal ganglia are involved in planning grip force.

“…the agonist muscle) (Sehm et al, 2010). Other human fMRI studies have also shown that the BOLD signal in the cerebellum increased in activation when individuals produce increased grip force amplitude (Dettmers et al, 1995; Keisker et al, 2009; Pope et al, 2005). …”

Specific cerebellar regions are related to force amplitude and rate of force development

et al. 2012

The human cerebellum has been implicated in the control of a wide variety of motor control parameters, such as force amplitude, movement extent, and movement velocity. These parameters often covary in both movement and isometric force production tasks, so it is difficult to resolve whether specific regions of the cerebellum relate to specific parameters. In order to address this issue, the current study used two experiments and SUIT normalization to determine whether BOLD activation in the cerebellum scales with the amplitude or rate of change of isometric force production or both. In the first experiment, subjects produced isometric pinch-grip force over a range of force amplitudes without any constraints on the rate of force development. In the second experiment, subjects varied the rate of force production, but the target force amplitude remained constant. The data demonstrate that BOLD activation in separate sub-areas of cerebellar regions lobule VI and Crus I/II scale with both force amplitude and force rate. In addition, BOLD activation in cerebellar lobule V and vermis VI was specific to force amplitude, whereas BOLD activation in lobule VIIb was specific to force rate. Overall, cerebellar activity related to force amplitude was located superior and medial, whereas activity related to force rate was inferior and lateral. These findings suggest that specific circuitry in the cerebellum may be dedicated to specific motor control parameters such as force amplitude and force rate.

The human sensorimotor system can be readily entrained to environmental rhythms, through multiple sensory modalities. In this review, we provide an overview of theories of timekeeping that make this neuroentrainment possible. First, we present recent evidence that contests the assumptions made in classic timekeeper models. The role of state estimation, sensory feedback and movement parameters on the organization of sensorimotor timing are discussed in the context of recent experiments that examined simultaneous timing and force control. This discussion is extended to the study of coordinated multi-effector movements and how they may be entrained.
