Feline cpg15 mRNA levels decrease in the LGN (filleddiamonds) and increase in primary visual cortex (filled andopencircles) during development. Error bars represent the SEM for 7–11 determinations (slides) obtained in two independent experiments, except for the E43 and P0 values, which are based on analysis of 4 and 3 determinations, respectively. Because results obtained for layers 2/3 and 5/6, quantified separately, were essentially identical, the numbers presented are only for layers 2/3 (filledcircles).
