aOver-represented functional classes in the feeding response gene groups. For clarity, gene groups with p>0.001 are				
not listed. See Supplemental Data for full comparisons. Gene lists are shown in Supplemental Table [5].				
bAll representation factors are significant at p<0.001. The probability was determined using the normal 				
approximation of the hypergeometric probability distribution.				
cFunctional classes are from Proteome except where noted.
