Octopamine and proctolin mimic spontaneous membrane depolarisations in Lucilia larvae.
Octopamine and proctolin at concentrations below 10(-8) M reversibly induce a spontaneous rhythmic depolarization which occurs in body-wall muscles of Lucilia larvae. The effect appears to be postsynaptic and mediated by receptors specific for each substance.
