Table 2. Morphometric information on identified ORNs of Drosophila melanogaster.
ORN identity is indicated by the sensillum type, relative spike amplitude (A, B, C, or D), odor-tuning receptor, and glomerular projection. Values are means ± s.e.m. Mitochondria analysis was performed for select ORN types. abx: novel basiconic sensillum, and the numbers of compartmentalized neurons are indicated in parentheses. * Information is available for one model. # Typical ac1 neurons. NA: information is not available because of incomplete sampling or segmentation. The odor response profiles for many of the characterized ORNs can be found in the DoOR database (http://neuro.uni-konstanz.de/DoOR/default.html).
