Fig. 7.

nAChR activation does not alter olfactory nerve (ON)-to-ET cell transmission. Ai: a few individual sEPSCs from the bottom trace in Fig. 1Aii on an expanded scale. Aii: frequency plot of sEPSCs from the same cell as in Fig. 1, A and B, voltage clamped at −70 mV. Arrowheads denote the start of a 1-s, 1 mM ACh/At application. Aiii: ACh/At does not alter the sEPSC frequency in ET cells (n = 21, P > 0.1). n.s., nonsignificant. Bi: recordings from an ET cell held at −70 mV, to observe the effect of glomerular ACh/At application (gray arrowhead) on evoked postsynaptic responses [evoked excitatory postsynaptic currents (eEPSCs)] to electrical stimulation of the ON (black arrowheads). Bii: expanded overlaid traces of eEPSCs under Cont conditions (top) and during the slow, ACh/At-induced current (1.5 s after the start of ACh/At application; bottom). Biii: nAChR activation does not alter eEPSC amplitudes. Black: Cont; gray: 1.5 s after the start of ACh/At puff; n = 8 cells, P > 0.6, K-S test. eEPSCs are normalized to the mean of the amplitudes under Cont condition.
