However, cetaceans may use their increased brain weight for processing acoustic information.
Three traits have independent correlations with life span: brain weight, body weight, and resting metabolic rate.
The more highly cephalized animals (i.e., those with higher brain weight), especially the primates, have greater lifetime energy outputs.
Mild prenatal stress decreased brain weight in both males and females, whereas extreme stress increased female brain weight.
In addition, the effect of second trimester equivalent prenatal alcohol exposure on brain weight was determined.
The cerebellum constituted 22% of the total brain weight, which conforms to findings in other baleen whales.
Hunt's analysis of brain weight indicated that an average African American's brain weighed five ounces less than the brain of an average white person.
Brain weight was not altered (Figure 2B).
Species averages for brain weight comprise both males and females.
Brain weight did not differ between the groups.
Whole brain weight (±0.001 g) was obtained from dissected brains following fixation (see [23] for further details).
