Mouse olfactory epithelia respond to stronger stimuli by recruiting more ORNs. (A) More cells responded to 50 μM (pink) n-amyl acetate than to 1 μM (red). Of 118 cells, 19 responded to 50 μM and only six responded to 1 μM n-amyl acetate. (B) Cells responding to the other four odors are mapped in the same preparation as shown in A. Responsive ORNs to different odors are represented by different colors. Cells responding to more than one odor are drawn in multiple colors. The numbers in parentheses are the numbers of responsive cells to the given odor(s). All odors were at 50 μM.
