The olfactory receptor genes map topographically onto the first relay station, a sheet of modules called glomeruli in the olfactory bulb. Up to 80% of the glomerular layer in the rat can be removed without significant effect on olfactory detection and discrimination (Bisulco and Slotnick 2003). If the remaining 20% of the glomeruli-and the olfactory receptor genes they represent-can subserve the functions of 1,100 genes, it implies that 350 genes in the human are more than enough to smell as well as a mouse.
