Fig. 2. The effects of laser ablation on the central projections of adult sensory neurones. Six different specimens showing the mesothoracic neuromere of the adult ventral nerve cord with sensory projections revealed immunocytochemically using GAL4 line C161 driving expression of CD8-GFP. In all panels, the ablated side is the left-hand side and anterior is upwards. (A-C) Illustrate typical defects in the central projections from the wing and notum. Typical defects include poor axon fasciculation, pathway errors and axon spiralling. (D,E) Defects in the formation of a specific terminal arborisation the posterior-dorsal projection (pd).
