Co-localisation of galanin and nNOS in a lamina III neuron. a Confocal image shows a lamina III neuron that is immunoreactive for nNOS (green). b The same field scanned for galanin (Gal, magenta) shows that the same cell is weakly immunoreactive. c A merged image. The images are from three optical sections at 2 μm z-spacing. Scale bar = 20 μm.
