1 In situ hybridization of three cloned SK channel subunits (SK1-3), the prime candidates likely to underlie Ca(2+)-dependent AHPs showed high levels of expression in regions presenting prominent AHP currents including CA1-3 regions of the hippocampus (SK1 and SK2), reticularis thalami (SK1 and SK2), supraoptic nucleus (SK3), and inferior olivary nucleus (SK2 and SK3)
2 The role of large-conductance Ca2+-dependent K+ channels (BK) in spike broadening during repetitive firing was studied using sharp electrode and computer modelling. The amplitude of the fast after-hyperpolarization (fAHP) rapidly declined during each train. Suppression of BK-channel activity with the selective BK-channel blocker iberiotoxin, the non-peptidergic BK-channel blocker paxilline, or calcium-free medium, broadened the 1st spike to a similar degree ( approximately 60 %)
