ΔFosB levels are not driven by ethanol consumption alone. Hierarchical clustering was performed and the resulting heat map of individual ΔFosB levels and the corresponding 9% ethanol consumption are shown. Green = ΔFosB less than mean, Black = closest to mean, Red = ΔFosB higher than mean. Yellow boxes highlight clusters consisting of mice from control groups, multiple concentration groups, or a mixture.
