Summary
The basal ganglia, specifically certain nuclei, are crucial for fine-tuning precision grip force control. This review integrates evidence, proposing a framework for their role within the broader grasping network.
Area of Science:
- Neuroscience
- Motor Control
- Grasping Network Research
Background:
- The grasping network's control has primarily focused on cortical regions.
- Subcortical basal ganglia nuclei are implicated in precision grip force control, but findings remain fragmented.
Purpose of the Study:
- To review and integrate evidence supporting the hypothesis of basal ganglia nuclei involvement in parameterizing precision grip force.
- To propose a conceptual framework for basal ganglia function within the grasping network for precision grip control.
Main Methods:
- Literature review synthesizing findings from human and animal studies.
- Analysis of anatomical connectivity between basal ganglia and cortical grasping network nodes.
Main Results:
- Converging evidence suggests key basal ganglia nuclei play a specific role in precision grip force parameterization.
- Established anatomical links exist between basal ganglia and cortical grasping network components.
Conclusions:
- The basal ganglia are integral to the grasping network, specifically in modulating precision grip force.
- A conceptual framework is proposed for basal ganglia's functional contribution to precision grip control within the wider network.

01:22Indirect Motor Pathways
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

01:18Hierarchy of Motor Control
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
01:20Motor Unit Stimulation
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
