Figure 2


Fig. 2. Representative examples of chemosignal-activated current obtained with chemical stimulation of vomeronasal sensory neurons (VSNs). (A) A male vomeronasal sensory neuron (VSN) when stimulated with catfish extract exhibited an outward current, as defined by the polarity of the response obtained at holding potential Vh=–60 mV. The black bar above the trace denotes the time (700 ms) that the VSN was presented with chemosignal delivered via a pressurized glass pipette approximately two cell-widths away from the VSN. (B) As in A but for a female VSN stimulated with female musk. Current record is representative of an inward current, as defined by the polarity of the response obtained at Vh=–60 mV.
