Mosaic organization of mouse ORNs in responding to different odors. (A) The preparation was viewed under fluorescence illumination, after being loaded with calcium green. (B) ORNs responded to different odors with distinct patterns. A total of 163 cells are mapped. 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). Filled and hollow arrows mark the tight clusters of octanal and n-amyl acetate responsive cells, respectively. All odors were at 50 μM.
