Figure 3: Representative EMG recording from four muscles of a head-fixed mouse performing a naturalistic climbing behavior.

The 5th row shows the position of the climbing wheel read out by a rotary encoder; changes in this value indicate that the wheel is turning and the animal is actively climbing. The total duration is 5 s. (A) Recording 36 days after implantation during climbing. (B) Recording 72 days after implantation in the same mouse after the wrist extensor electrode failed.
