Abstract
Two types of potassium channels of identified (p-) neurones of the lee ch (Hirudo medicinalis) were investigated by using the patch-clamp tec hnique. The open-state probability of these channels in cell-attached patches can be reduced by addition of 5-hydroxytryptamine to the bath solution. After excising the patches the application of alkaline phosp hatase to the cytosolic face of the patch increases the open probabili ty. The 5-HT1A-receptor agonist buspirone mimics the effect of 5-HT Ou r experiments show that the effect of 5-HT might be due to a channel p hosphorylation via a 5-HT1A-receptor subtype.
