Fig. 6. Analysis of chemosignal-activated reversal potentials supports a cationic receptor potential in vomeronasal sensory neurons (VSNs) of S. odoratus. (A,B) Response of a female neuron to (A) catfish extract (1:10 dilution), (B) female musk (1:100 dilution). Broken horizontal lines indicate baseline currents. (C,D) Plotted current–voltage relation for the families of currents evoked in A and B, respectively. (E,F) Scatter plot of estimated reversal potentials derived in C and D for chemosignal-evoked outward (E) and inward (F) currents, respectively. For each chemosignal, the vertical line depicts the mean reversal potential if more than one sample was obtained. The average reversal potential for the outward current was –28.2±2.37 mV (N=30) and that for the inward current was –5.7±7.79 mV (N=10).
