FIG. 5.

A 3-dimensional surface that quantifies the magnitude of heterogenic inhibition from G onto FHL during locomotion as a function of force and time. To quantify the magnitude of heterogenic inhibition from G onto FHL during locomotion, response differences are calculated for every 5 ms over the ramp-and-hold stretch by subtracting the polynomial fits for RD from the polynomial fits from R. A 3-dimensional surface is created from the series of response difference calculations. The heterogenic inhibition from G onto FHL during locomotion remains relatively constant over time and FHL background force.
