Since the ‘neurite development’, ‘cell projection morphogenesis’ and ‘axonogenesis’ categories contained many common genes, these genes were combined into a single ‘neurite development’ category (Table 2). In addition, individual literature searches added 5 more significant genes to the combined category. Among the 18 genes in the ‘neurite development’ category that significantly differed, 17 genes had higher expression in the ethanol group.
