Double labelling of axons
A: false color image of interneuron (CFP-labelled, showed in green) and motorneuron axons (GFP-labelled, showed in red) in the ventral cord.Side view. Animal orientation: anterior left, dorsal up. B: cross-section through the ventral cord at the position marked by the arrowhead in A. C, D: same images after deconvolution with Huygens2. E, H: single channel images of C,D. A larger region of the ventral cord with cell bodies of motorneurons visible. J-M:Four cross-sections through the ventral cord at positions indicated by arrowheads in I.
