TEMPERATURE DEPENDENT CILIARY RHYTHMICITY IN<i>MYTILUS EDULIS</i>AND THE EFFECTS OF MONOAMINERGIC AGENTS ON ITS MANIFESTATION

Abstract

Lateral ciliary activity of the bivalve mollusc Mytilus edulis was studied in the field and in the laboratory. A diurnal rhythm corresponding to the environmental temperature changes was found. This behavior was modified by treating animals with serotonergic and dopaminergic agents, disrupting the serotonin and dopamine innervation of the cilia. The study shows that manifestation of this temperature-dependent rhythmicity is due peripherally and centrally to monoaminergic path-ways.
