A) Diagram depicting the 1-nerve stimulation assay designed to reveal the contribution of dPVs to motor activity evoked by stimulation of ipsilateral cutaneous nerves. Nerve cuffs were implanted on the right sural nerve and left saphenous nerve. <t>EMG</t> <t>electrodes</t> were implanted into the right and left semitendinosus (St, knee flexor), right vastus lateralis (VL, knee extensor), left tibialis anterior (TA, ankle flexor) and right and left gastrocnemius (Gs, ankle extensor). EMG responses were recorded from hindlimb flexors and extensors following stimulation of cutaneous nerves (saphenous / sural nerve). B) Example St EMG responses to stimulation of the right saphenous nerve at 5 times threshold (see methods) in dPV norm (top) and dPV abl (bottom), during the experiment described in D. C) Latency to response to stimulation of the saphenous (left) or sural (right) nerves of ipsilateral hindlimb muscles during the experiment depicted in D. D) Top-diagram of the 2-nerve stimulation assay applied to reveal if dPVs mediate sensory-evoked ipsilateral inhibition. Bottom-experiment timeline. Nerve cuffs and EMG electrodes were placed as in D. Stimulation of the contralateral cutaneous nerve (saphenous/ sural) alone (black lightning) was used to calculate the expected response in the absence of sensory evoked ipsilateral inhibition. Following, both nerves were stimulated (yellow lightning), with variable delays and compared to the expected response to reveal ipsilateral inhibition. E) Top-expected Gs EMG response to stimulation of a single cutaneous nerve in dPV abl (left) and dPV norm (right), averaged over 20 responses. Bottom-expected responses (black) superimposed on single trial responses to stimulation of both cutaneous nerves (yellow). Left-response to stimulation of both nerves (15 ms delay), shows a “dip” that is absent in the expected response, indicating ipsilateral inhibition. Right-no “dip” is seen (0 ms delay), suggesting a loss of inhibition. For each mouse and each muscle, the delay in which responses were best aligned was chosen for further analysis. F) Percent inhibition (the percentage of trials where inhibition was detected) in hindlimb muscles, mediated by ipsilateral saphenous (left) and ipsilateral sural (right) nerves, following the experiment in G. Statistical analysis was done using Mann Withney test, with *p < 0.05 and **p < 0.005. Graphs show average +S.E.M. blue and red denote dPV norm and dPV abl , respectively.
