The courtship behaviour of Drosophila funebris and of Drosophila melanogaster mutant ebony is described. A method of recording from the brain of these insects is developed. This method resulted in providing additional information concerning the effect of the gene ebony on behaviour. (Author)
The courtship behaviour of Drosophila funebris is described. A map showing the main regions of the brain of this fly is given and the electrophysiological method used to investigate the nervous control of the behaviour of this species is described. The way is which this method will be used in future experiments to study the effects of genetic changes in the nervous system is outlined. (Author)
