Myomatrix arrays for high-definition muscle recording

Area of Science:

• Neuroscience
• Biomedical Engineering

Background:

• Understanding motor control relies on analyzing neural activity and motor output.
• Current methods for recording motor output lack resolution and scalability across species and muscle types.

Approach:

• Introduced Myomatrix arrays: high-density, flexible electrode arrays for recording muscle fiber activation.
• Enabled stable recordings of individual motor units during natural behaviors in multiple species.

Key Points:

• Myomatrix arrays provide unprecedented resolution of muscle activity.
• Facilitates detailed monitoring of the nervous system's motor output.
• Applicable across diverse species (mice, rats, primates, songbirds, frogs, insects) and muscle morphologies.

Conclusions:

• This technology enables detailed study of neural control of complex behaviors.
• Expected to accelerate advances in understanding motor system pathologies.
