| Outline of Final Research Achievements |
To unravel the neural basis of the evolution of mate preference, we aimed to elucidate the neural basis of the interspecific differences in the preference for courtship songs in Drosophila melanogaster and D. simulans. We found that the morphological characteristics of the 1st, 2nd, and 3rd order neurons and courtship command neurons are well conserved between the two species. We also compared the song preference of the neural activity of auditory 1st and 2nd order neurons between species and showed that there are slight interspecific differences in the neural response of 2nd order neurons. The results show that the interspecies differences in auditory information processing already exist at the level of neural activity of second-order neurons.
