Expression patterns of DE genes known to be involved in memory formation. The log2-fold change shows if a transcript is upregulated (green, <1.5 or >1.5) or downregulated (pink, <−1.5 or > −1.5), n.s. = not significantly DE. Expression levels at 0 h, 4 h, and 24 h after conditioning are presented for N. vitripennis (Nv, left) and N. giraulti (Ng, right). For most genes, only a single transcript is DE and shown in this figure. Multiple DE transcripts of the same gene are indicated by (1), (2), etc. It is also indicated if an antisense transcript is present for each gene (grey = present, no color = not present).
