Fig. 5 Econding swim onset, speed, and duration in the nMLF

(A) Activity of nMLF neurons during slow swim episodes. Top panel: EMG recording of a slow swim episode with small muscle units. Middle panel: medial vGlut2⁺ neurons are recruited prior to the onset of the swim episode and maintain their recruitment during the duration of the episode (Peri-stimulus time histograms [PSTHs], bin width = 0.01 s). Bottom panel: lateral vGlut1⁺ neurons are not recruited during slow swim episodes.

(B) Transition between slow and fast swim speeds. Top panel: EMG recording of an episode with a switch from slow to fast swim. Middle panel: medial vGlut2⁺ neurons increase their activity when the swim switches from slow to fast swim. Bottom panel: lateral vGlut1⁺ become recruited only during fast swim speed characterized with the onset of large muscle units.

(C) Start and end of a fast swim episode. Top panel: EMG recording of a fast swim episode with larger muscle units active at high swim frequency. Middle panel: medial vGlut2⁺ neurons are active before the onset of the fast swim episode and display a strong activity increase at the onset with fast swim episode. Bottom panel: lateral vGlut1⁺ neurons become active shortly prior to the onset of the fast swim episode characterized with large muscle units.
