In contrast to the few significant GO MF categories found in the ACB-shell between the ethanol and water groups, there were 15 significant MF categories in the CeA (results not shown), several of which had 10 or more genes listed, e.g., ‘G-protein coupled receptor activity’, ‘ion channel activity’, ‘receptor signaling protein activity’, and transmembrane ‘receptor activity’. Although the ‘receptor signaling protein activity’ MF category was in common between the ACB-shell and CeA, there were no genes in common in this category between the 2 regions. Most of the genes in the significant MF categories for the CeA could also be found within the BP categories.
