Maxillary palp glomeruli and ipsilateral projections in the antennal lobe of Drosophila melanogaster.

The antennal lobe was examined by Golgi-silver impregnation to differentiate the glomeruli depending on the source and types of inputs. Thirty-five of the 43 'identified' olfactory glomeruli were Golgi-silver impregnated in the present study. Seven glomeruli compared to three, reported previously, were found to be targets of maxillary palp chemosensory neurons.

Golgi analysis of tangential neurons in the lobula plate of Drosophila melanogaster.

The lobula plate (LP), which is the third order optic neuropil of flies, houses wide-field neurons which are exquisitely sensitive to motion. Among Diptera, motion-sensitive neurons of larger flies have been studied at the anatomical and physiological levels. However, the neurons of Drosophila lobula plate are relatively less explored.
