encephalization
encephalization (ɛnˌsɛfəlaɪˈzeɪʃən) [f. Gr. ἐγκέϕαλ-ος brain + -ization.] 1. An evolutionary increase in the complexity or relative size of the brain; a shift of function from non-cortical parts of the brain to the cortex.1938 J. F. Fulton Physiol. Nerv. Syst. p. viii, Owing to greater encephalizati... Oxford English Dictionary

Encephalization quotient
Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between Encephalization is a characteristic of a species. wikipedia.org

Why are dolphins so smart? It seems that dolphins have (among?) the highest encephalization quotients found outside of humans, higher even than chimpanzees. By the "use it or lose it" principle this indicates that int...
It's less about the brain size, I think, more about the metabolic cost of brains. Brains are among the most costly organs to keep what it comes to oxygen demand. Air-breathing increases available oxygen for the body, hence mammals have larger brains that for example fish. In diving animals the metab...

Brain–body mass ratio
A more complex measurement, encephalization quotient, takes into account allometric effects of widely divergent body sizes across several taxa. The raw brain-to-body mass ratio is however simpler to come by, and is still a useful tool for comparing encephalization within species or between fairly wikipedia.org

Brain size
The encephalization quotient for humans is between 7.4-7.8. When the mammalian brain increases in size, not all parts increase at the same rate. While humans have the largest encephalization quotient of extant animals, it is not out of line for a primate. wikipedia.org

The result of the experiment concluded that the energy cost of encephalization might have involved in the evolution of brain size in both endothermic as This also shows that the presence of the energetic constraints of encephalization is also being applied to homeothermic vertebrates. wikipedia.org
