| Popis: | The conditioned inhibition of courtship in male was quantitatively and sequentially studied in the Drosophila melanogaster neurological mutant no-bridgeKS49 (nob). After being paired first with a previously fertilized (unreceptive) female, wild-type Berlin males court virgin, receptive females less vigorously (if not at all) then naive wild-type males do. This conditioned inhibition is characterized by the latency of the first contact, the frequency and duration of the courtship acts, and the sequential organization of the kinetograph. In contrast, when presented with the same sequence, the nob males were not inhibited, as reflected in all courtship parameters; their courtship performance with virgin females was similar to that of naive nob males. This behavior pattern could be due to the disorganization of their protocerebral bridge interrupting inhibitory interactions between the two brain hemispheres, thereby causing uncoordinated descending inhibition of the motor behavior. The results suggest that the central complex could be the high brain center controlling this kind of learning. |
