Abstract

The pattern of visually induced local metabolic activity in the optic lobes of two structural mutants ofDrosophila melanogaster is compared with the corresponding wildtype pattern which has been reported in Part I of this work (Buchner et al. 1984b). Individualoptomotor-blind H31 (omb) flies lacking normal giant HS-neurons were tested behaviourally, and those with strongly reduced responses to visual movement were processed for 3H-deoxyglucose autoradiography. The distribution of metabolic activity in the optic lobes ofomb apparently does not differ substantially from that found in wildtype. In the mutantlobula plate-less N684 (lop) the small rudiment of the lobula plate which lacks many small-field input neurons does not show any stimulus-specific labelling. The data provide further support for the hypothesis that small-field input neurons to the lobula plate are the cellular substrate of the direction-specific labelling inDrosophila (see Buchner et al. 1984b).
