Signal density maps in the spinal cord and medulla oblongata sections from female and male embryos hybridized with PCDH11X/Y and NLGNX/Y. The distributions of Y and X signals in different tissue sections are displayed as kernel density estimation plots where Y signal density is displayed in red and X signal density in cyan. The intensity of the colour reflects the density of the signal. Overlap in signal densities results in a mixed colour, whereas equal proportion of Y and X results in white colour. The outline of the tissue is indicated by a dashed white line. Orientation of the SC tissues is ventral down and dorsal up. The signal density in the female spinal cord is displayed in a for PCDH11X and in b for NLGN4X. c, d Signal density in the female medulla oblongata for PCDH11X and NLGN4X, respectively. e Signal density of PCDH11X/Y in the male spinal cord is shown individually for the two homologs as well as a plot of the two transcript densities combined. NLGN4X/Y is displayed in the same way on f. Signal densities in the male medulla oblongata are shown in g and h for PCDH11X/Y and NLGN4X/Y
