Monopolar recording from the central column and two peripheral columns (proximal (top) to distal (bottom)) recorded from tattoo electrode (solid color) and commercial electrode (overplayed transparent black color) during resting trials followed by a 60 % MVC contraction trial with a trapezoidal trajectory of the force with 10 seconds of steady state contraction. The tattoo location and electrode layout (rows (R) and columns(C)) is shown with a magnified view.
