Depiction of the MEG experimental paradigm. The trial length was 10 s in length. The participants started each trial at rest for 5000 ms. Subsequently, a target moth would appear, prompting the participant to generate an isometric knee extension force that matched the force value. The target forces varied between 15 and 30% of the participant’s maximum isometric force and were available to be matched for up to 5000 ms. A successful match occurred when the bug that represented the target force was inside of the frog’s mouth for 300 ms. The participants completed 120 target matching trials.
