Fig. 7. Vomeronasal sensory neurons (VSNs) from S. odoratus exhibit a
chemosignal-evoked conductance decrease linked with outward currents. A VSN
from a female S. odoratus was held at 60 mV
(Vh) with five hyperpolarizing steps to 90 mV
(Vc) injected prior (black), during (gray) and following
(black) chemosignal stimulation with catfish extract. Inward
chemosignal-evoked conductance changes were not tested.
