Figure 3. CC recording of cultured TG neurons stimulated with odorants in the presence and absence of CPZ.

Figure 3

Exemplary CC recordings from cultured TG neurons upon stimulation with vanillin, HTPA, helional, and geraniol alone and with CPZ. Membrane potential changes and RMP of recorded neurons upon stimulation with: vanillincap-sensitive: RMP: −45 mV; vanillin: Δ10 mV, vanillin+CPZ: Δ7 mV, cap: Δ20 mV, men: Δ0 mV; vanillinmen-sensitive: RMP: −62 mV; vanillin: Δ0 mV, vanillin+CPZ: Δ0 mV, cap: Δ0 mV, men: Δ29,5 mV; HTPAcap-sensitive; RMP: −67 mV; HTPA: Δ14.6 mV, HTPA+CPZ: Δ10.3 mV, cap: Δ27.5 mV, Δ2.6 mV; HTPAmen-sensitive; RMP: −61 mV; HTPA: Δ6.3 mV, Δ3.7 mV, cap: 0 mV, men: Δ31.4 mV; helionalcap-sensitive: RMP: −73 mV; helional: Δ29.1 mV, helional+CPZ: Δ22 mV, cap Δ67 mV, men: 0 mV; helionalmen-sensitive: RMP: −50 mV; helional Δ7.2 mV, helional+CPZ: Δ7.8 mV, cap: Δ0 mV; men: Δ25 mV; geraniolcap-sensitive: RMP: −67 mV; geraniol: Δ18 mV, geraniol+CPZ: Δ14 mV, cap: Δ53 mV, men Δ0 mV; geraniolmen-sensitive: RMP: −60 mV; geraniol: Δ17.6 mV, geraniol+CPZ: Δ14.5 mV, cap: Δ2 mV; men: Δ23 mV. Capsaicin- and menthol-evoked action potentials were cut at −30 mV (vanillin), −20 mV (HTPA), 0 mV (helional), and at −10 mV (geraniol). Stimulus applications are indicated by highlighted (gray) regions.
