Fig. 2. Afferent conduction times of different mechanoreceptors on the segments of the middle leg of Schistocerca gregaria. Signal averages (64 sweeps) are triggered by the action potential from the vicinity of the soma (upper trace) and afferent in the main leg nerve root at the ganglion (lower trace). (A) Posterior overview of leg segments and location of some of their mechanoreceptors. (B) Averages axonal conduction time of campaniform sensilla (CS) afferents from the posterior trochanteral group (trCS5). (C) Averages axonal conduction time of CS afferents from the posterior femoral group (feCS2). (D) Axonal conduction time of CS afferents from the two distal tibial CS (tiCS5). (E) Comparison of axonal conduction times of tibial spur CS afferents (1–8) from the posterior row of receptors (means ± S.D.; N=5).
