It uses 3D printing to create molds, and polyvinyl alcohol (PVA-c) is used as the tissue mimicking material. Neuroscience Muscle Velocity Recovery Cycles to Examine Muscle Membrane Properties Agnes Witt1, Hugh Bostock2, Werner J. Z'Graggen3, S.

MVRCs enable in vivo assessment of muscle membrane potential and alterations in muscle ion channel function in relation to pathology, and it enables the demonstration of muscle depolarization in neurogenic muscles.
