Fig. 9 . Representation of the ten tested odours in the AL glomeruli. Patterns are drawn based on the morphology of 19 stained projection neurones, where glomeruli targeted by responding neurones are blue. For glomeruli harbouring the dendritic arborisations of more than one neurone, the number of innervating neurones is given on the glomerulus. Numbers in the lower left-hand corners are the numbers of stained projection neurones for a given compound.
