title: [The role of cAMP in generating mollusk neuron responses, related to negative slope conductance, to dopamine application].
abstract: Dopamine (DA)-induced steady-state inward current has been studied in isolated mollusc neurons through two different mechanisms: an increase in the slow potential-dependent Na(+)-conductance and a decrease in the K(+)-conductance. Dibutyryl-cAMP mimicked the both types of DA-responses. 3-Isobutyl-1-methylxanthine (IBMX) in low concentration potentiated DA-responses and in high concentration mimicked them. It was concluded that most of DA-induced inward current responses associated with a negative slope conductance are mediated by cAMP.
