Genes enriched in rat FMCx, TCx or OCx. Heat-map illustrating relative expression levels of regionally enriched genes across the six replicates of rat FMCx, TCx and OCx. Each pixel corresponds to a log2-transformed, high-level mean normalised, expression level in a single sample. Red and blue colours indicate expression levels above and below average, respectively. Genes in bold letters were selected for QPCR validation. Numerals (4,6,8) refer to the individual rats. L, left hemisphere; R, right hemisphere. FMCx, fronto-medial cortex; TCx, temporal cortex; OCx, occipital cortex.
