Summary
The striatum plays a similar role in natural and brain-machine interface motor learning. Functional interactions in corticostriatal networks develop during neuroprosthetic learning.
Area of Science:
- Neuroscience
- Motor Control
- Brain-Computer Interfaces
Background:
- Corticostriatal dynamics change during natural motor learning.
- The role of these dynamics in neuroprosthetic tasks remains unclear.
Purpose of the Study:
- Investigate corticostriatal interactions during brain-machine interface (BMI) learning in rats.
- Determine how neural activity and functional connectivity change as animals learn to control a BMI.
Main Methods:
- Recorded neural activity in the striatum and primary motor cortex of rats during BMI learning.
- Analyzed changes in single-unit firing rates and spike-field coherence over learning progression.
Main Results:
- Striatal firing rates significantly increased from early to late learning stages.
- Alpha-band spike-field coherence between primary motor cortex and striatum showed a marked increase in late learning.
Conclusions:
- The striatum appears to support similar functions in both natural and neuroprosthetic motor learning.
- Learning to control a BMI involves the development of functional interactions within corticostriatal networks, particularly in the alpha frequency band.
