Motor Unit Stimulation

Motor 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...

Summary

Local field potentials (LFPs) provide robust signals for decoding upper limb muscle activity. This finding suggests LFPs are a valuable, long-lasting signal source for advanced neural prostheses.

Area of Science:

Neuroscience
Motor Control
Biomedical Engineering

Background:

Local field potentials (LFPs) in the primary motor cortex contain information about reach targets and movement kinematics.
LFPs may offer more robust and longer-lasting neural signals compared to action potentials (spikes).

Purpose of the Study:

To investigate if LFPs can decode upper limb muscle activity, a complex motor signal.
To compare the decoding performance of LFPs against spikes for muscle activity.

Main Methods:

Electromyograms (EMGs) were recorded from proximal and distal upper limb muscles in monkeys.
Monkeys performed reach-to-grasp and isometric wrist force tasks during neural recordings.

Main Results:

LFPs successfully decoded activity from both proximal and distal upper limb muscles.
Decoding performance using LFPs rivaled that achieved using spikes.

Conclusions:

Motor cortical LFPs encode a wider range of movement aspects than previously recognized.
LFPs represent a promising, durable signal for neural prosthetics development.
