Figure 5. Correlation of odorant and forskolin responses.

Figure 5

A, ORN (stage 53) excited by both l-glutamine (200 μm) and forskolin (50 μm). B, ORN (stage 51) excited by forskolin (50 μm) but not by the mixture of amino acids (AA, 200 μm). C, ORN (stage 54) excited by an amino acid (l-methionine, 200 μm) but not by forskolin (50 μm). D, occurrences of correlated and uncorrelated responses to forskolin and amino acids. Sixty-nine out of the 90 ORNs tested responded neither to amino acids nor to forskolin.
