Inositol-1,4,5-trisphosphate Induces Responses in Receptor Neurons in Rat Vomeronasal Sensory Slices

Using the whole-cell mode of the patch-clamp technique, we recordedaction potentials, voltage-activated cationic currents and putativesecond messenger-activated currents in receptor neurons in thevomeronasal sensory epithelium of female rats. The resting membranepotential and input resistance were –45.5 ± 2.5mV (mean ± SEM, n = 39) and 1.5 ± 0.2 G
