"With ChTX in the pipette solution (1 µM), BK channels of inside-out patches were also inhibited (Fig. 10B; n = 5). Pipette tips were filled with the standard intra-cellular solution and backfilled with ChTX-containing solution, so that channel openings were present initially, and then blocked as ChTX diffused from the shank into the electrode tip."p.194 "Perfusion of 0.5 mM TEA-containing solution inhibited BK channel openings in outside-out patches in both P14 (n = 4) and P1 (n = 2) neurons (Fig. 10C). The effects of TEA appeared as a reduction in unitary current amplitude, presumably because TEA blocks and unblocks the channel with very fast kinetics not resolvable by the recording system (Benham et al. 1985); Reinhart et al. 1989; Yellen 1984)."p.194 "When perfused over inside-out patches, trifluoperazine (50 µM), a phenothiazine derivative, also blocked BK channel activities in both P14 (n = 3) and P1 (n = 2) neurons (Fig. 10D) in a pattern similar to that reported by Ikemoto et al.

"Another channel seen in these patches had longer open times, exhibited prominent channel noise, was inwardly rectifying at strongly depolarized potentials, and had a mean conductance of 20.3 +- 1.2 pS (n = 7; Fig. 3). Ensemble averages of this current gave pure I(K)-like currents in different patches, both inactivating (n = 3; Figs 1C and 3A) and non-inactivating variants (n = 4; Fig. 1B). Thus it appears that a single type of channel underlies the different forms of the slow, I(K)-like current, but its inactivation properties may vary.".pp.613-614 "For convenience, the fast transient and slowly inactivating/non-inactivating currents seen in these patches will henceforth be called I(A) and I(K), respectively."p.614 |

"Three hundred ninety-six slow-gating ("slow") and 9 fast-gating ("fast") BK channels were observed in 218 inside-out patches excised from P0-P28 neurons. The slow channel, which was the most prominent type in both mature and immature neurons, has properties similar to those expected for BK channels (Farley and Rudy 1988; Reinhart et al. 1989). However, fast channels were only observed in immature neurons."p.4195 |

"In three patches channel openings were observed with short first latency (Fig. 9A). Following several openings the channels entered a long closed duration (Fig. 9A). The unitary conductance of this channel was 13 +- 1 pS (Fig. 9C, n = 3). Ensemble currents revealed a fast inactivating current (Fig. 9B). The decay of the current was fitted to a single exponent with time constants of 36 ms at 60 mV above the resting membrane potential, 28 ms at 80 mV and 34 ms at 100 mV (Fig. 9B). Similar time constants were observed in two or more patches that also contained other types of channels (see also Fig. 12). This inactivation time constant was four times larger than the time constant obtained in this voltage range fir the fast K+ current in nucleated patches (Figs 1 and 6)."pp.631-632 |

"Channels that displayed a long latency to the first opening, when the voltage was stepped to 40 mV above the resting membrane potential (Fig. 11A), were observed in three additional patches. The unitary channel current at this voltage was smaller than that observed for the delayed channel described in Fig. 10. The unitary conductance of this channel was 9.5 +- 0.5 pS (Fig. 11C, n = 3). The rate of inactivation of these channels was faster than that found for the 16 pS channel (Fig. 10). The inactivation time constant, determined from ensemble currents, was 190 ms at 40 mV above the resting membrane potential, 130 ms at 60 mV, and 200 ms at 80 mV (Fig. 11B). The inactivation time constant 120 mV above the resting membrane potential was calculated to be 250 +- 50 ms (n = 3).

"In four patches a channel that displayed a long latency to the first opening when the voltage was stepped to 40 mV above the resting membrane potential (Fig. 10A) was observed. Burst duration increased while the intra-burst closed time decreased as a function of the applied voltage (Fig. 10A). The unitary conductance of this channel was 16 +- 1 pS (Fig.10B, n = 4). A long closed duration was observed in most traces when voltage steps of 5s to +60 mV above the resting membrane potential were applied (Fig. 10C). Summation of 45 sweeps revealed a slowly inactivating ensemble current (Fig. 10C). The decay of the ensemble current was best fitted to a single exponent with a time constant of 5.5 +- 2 s at +60 mV above the resting membrane potential (n = 3).

"In four patches (two somatic and two dendritic at 60 and 300 µm) a fourth type of K+ channel was observed. This K+ channel had a unitary conductance of approximately 150 pS (n = 2) matching that of the large conductance Ca2+-activated K+ (BK) channels observed in dissociated neocortical pyramidal neurones (Kang et al. 1996). The low frequency of occurence of this K+ channel subtype may be due to a lower channel density than the one reported for dissociated neocortical pyramidal neurones (Kang et al. 1996) or to a low channel opening probability due to a low intracellular Ca2+ concentration."p.635 |
