With the "doggie-marshmallow test," a self-control experiment that required its subjects to hold off eating a treat for long periods, Berns's team quickly figured out that not all dogs would activate the same cognitive mechanism while performing the same task.
The tumor cells were inoculated at four places in each animal in order to provide self-control experiment and reduce the necessary number of experimental animals.
In addition, a self-hybridization control experiment was performed to evaluate and overcome potential gene-specific dye bias.
SAM procedure [26] was applied to identify loci with significant amounts of nascent DNA by comparing the ratios of copy number at individual loci in HU-treated experiments with the self-hybridization control experiments.
In this study, data from both channels were highly correlated as the Pearson correlation coefficients between Log2 Cy3 signal intensity versus Log2 Cy5 signal intensity of the 11 and 14 dpa self-hybridization control experiments [ 7] were 0.985 and 0.986, respectively.
Alas, we have no control experiment.
Amazing powers of self control.
