[The fan-shaped and ellipsoid bodies of the brain central complex are involved in the control of courtship behavior and communicative sound production in Drosophila melanogaster males].
To elucidate the role of the fan-shaped and ellipsoid bodies (FB and EB) of the central complex of Drosophila melanogaster brain in the control of male courtship behavior and singing, we analyzed characteristics of the courtship behavior and parameters of the communicative sound signals accompanying it in wild type flies and in flies from 5 mutant strains with various anatomical defects in FB and EB. The following strains of flies were used for experiments: Canton S (wild type, the control), eboKS263 with defects only in EB and ebo1041, ceb849, ceb892 and cbdKS96 with both the FB and EB damaged in different manner. The data obtained suggest that the FB and EB are involved: 1) in maintenance of a high courtship activity level, 2) in the control of accuracy of male following movements when courting a female, 3) in the control of the form and stability of sound elements in courtship songs, 4) in the control of the rhythmic structure of courtship songs determined by the stability of the pacemakers, and 5) in setting up a correspondence between the current behavior and the external situation.
