Projections and Functional Implications of Labellar Neurons from Individual Sensilla of Drosophila Melanogaster

Our previous studies using Golgi silver impregnations from labellar sensilla of adult Drosophila melanogaster had revealed seven distinct neuronal types projecting in the suboesophageal ganglion of the brain. These are: coiled fibre (type I); shrubby fibre (type II); ipsilateral ventral fibre (type III); ipsilateral dorsal fibre (type IV); contralateral ventral fibre (type V); contralateral dorsal fibre (type VI) and central fibre (type VII) (Nayak and Singh, 1985).
