Quantification of UCP1 immunostaining in cetartiodactyl cerebral cortex. Graphical representation of the results of the stereological analysis of the percentage of cortical neurons immunopositive for UCP1 in the occipital and anterior cingulate cortices of the species studied. For each species the brain mass is given in grams next to the name on the x-axis. Note that the average percentage of cortical neurons immunopositive for UCP1 in the artiodactyls studied was 35.4%, while in the cetaceans studied it was 89.9% (Table 1, error bars on average bars represent one standard deviation). The Western immunoblot in the middle of the graph shows the specificity of the UCP1 antibody to brown fat
