OlfDNCX mice exhibit a reduced glomerular activity map to octaldehyde. A and B. Pseudocolor contour maps showing averaged octaldehyde-evoked glomerular activation patterns in wild type mice (A) and their OlfDNCX littermates (B) (n = 8 for each map). The color denotes the number of activated glomeruli in a region spanning 216 μm in the rostrocaudal direction and 30 degrees in the angle dimension. The pseudocolor scale varies linearly from blue (0 glomerulus) to red (16 glomeruli). C. p values for a pixel by pixel Mann-Whitney test of differences between the odor maps in (A) and (B). Areas enclosed by black contour lines are regions that differ significantly (p < 0.006). The pseudocolor scale varies logarithmically from a p value of 0.5 (blue) to 10^-5 (red). D. A diagram indicating the locations of domains that differ between OlfDNCX and wild type mice.
