title: Relationship between two voltage-dependent serotonin responses of molluscan neurones.
abstract: A serotonin (5-HT)-induced slow inward current was reanalyzed in identified snail neurones and found to result from a decrease in a voltage-dependent K+-conductance, sensitive to [Ca2+]0 changes. 5-HT evoked in the same neurones an increase in the spike plateau known to be associated to a K+-conductance decrease. Both 5-HT responses appear to reflect the same decrease in K+-conductance.
