Figure 6

Arc mRNA expression across behavioral groups, cortical layer and sub-cellular compartments. (A) Average percentage of cells positive for Arc mRNA (in nucleus and/or cytoplasm) in images from cortical layers 1–2, 3–4, and 5–6 for each behavioral group. The difference in layer-dependent expression between SØ and S1 mice, both of which only had silence just before sacrifice, indicates an effect of prior sound exposure. (B–D) Average percentage of Arc mRNA expression in each compartment, was pooled across layers 3–6, according to group. Nuclear-positive (cytoplasm-positive) cells have expression in the nucleus (cytoplasm), but may also have cytoplasmic (nuclear) expression. Cytoplasm ONLY cells express Arc mRNA only in the cytoplasm. Differences between S2 and S1S2 in panels B and C, and SØ and S1 in B and D indicate an effect of prior sound exposure. Asterisks in each graph represent significance by posthoc HSD test (p<0.05) for indicated pairs. Error bars represent standard error.
