| Single-channel recordings from inside-out membrane patches excised from toad chemosensory cilia showed the presence of 4 different types of KCa channels, with unitary conductances of 210, 60, 12, and 29 and 60 pS, high K+-selectivity, and Ca2+ sensitivities in the low micromolar range (Delgado R, Saavedra MV, Schmachtenberg and Sierralta J and Bacigalupo J, 2003485 ). |
| I CNG | |
| Present in lower density than in the cilia (Nakamura and Gold GH, 1987112 , see also Suzuki N, 1989128 ). In addition, IP3 gated ion channel; found in the autodendritic membrane (Hatt and Ache BW, 1994 [lobster]80 ; Fadool DA and Ache BW, 1994 [lobster]55 ).
The basal conductance of unstimulated frog ORN was investigated using whole-cell and perforated-patch recording. It was found that under physiological conditions, gating of CNG channels contributes approximately 0.06 nS to the resting neuronal conductance (Pun RY and Kleene SJ, 2003486 ). |
| I Cl,Ca | |
| Present in lower density than in the cilia.
Properties of this channel in rat, and its functional interplay with the CNG channel, were studied by using inside-out membrane patches excised from ORN dendritic knobs/cilia (Reisert J, Bauer P and Yau KW and Frings S, 2003483 ), and inside-out membrane patches (Hallani and Lynch JW and Barry PH, 1998484 ). |
