encephalization quotient

Humans however have the largest encephalization quotient of any animal.

The encephalization quotient for humans is approximately 4.6.

Behavioural complexity in living animals can to some degree be observed directly, making the predictive power of the encephalization quotient less relevant.

This species has a cranial capacity of 167 cc and an encephalization quotient of 1.5.

Crows are now considered to be among the world's most intelligent animals with an encephalization quotient approaching that of some apes.

The encephalization quotient varies widely between species.

A standard formula for assessing an animal's brain size compared to what would be expected from its body size, is known as the encephalization quotient.

While humans have the largest encephalization quotient of extant animals, it is not out of line for a primate.

A more complex measurement, encephalization quotient, takes into account allometric effects of widely divergent body sizes across several taxa.

Perhaps surprisingly for such a widespread and successful species, the Virginia opossum has one of the lowest encephalization quotients of any marsupial.

The cephalization factor and the subsequent encephalization quotient was developed by H.J. Jerison in the late 1960s.

Encephalization quotient (EQ)

This information is useful for calculating relative brain size, RBS, and encephalization quotient, EQ.

Within the encephalization quotient proposed by Jerison in 1973, values above 1 are classified big brained, lower than 1 are small brained.

The encephalization quotient (EQ) of dinosaurs, a measure of brain size calculated using brain endocasts, varies on a spectrum from bird-like to reptile-like.

In an attempt to use cranial capacity as an objective indicator of brain size, the encephalization quotient (EQ) was developed in 1973 by Harry Jerison.

The most widely accepted way of comparing brain sizes across species is the so-called encephalization quotient (EQ), which takes into account the nonlinearity of the brain-to-body relationship.

Biologist Stephen Jay Gould has noted that if one looks at vertebrates with very low encephalization quotients, their brains are slightly less massive than their spinal cords.

Comparison of a particular animal's brain size with the expected brain size based on such allometric analysis provides an encephalization quotient (EQ) that can be used as another indication of the animal's intelligence.

Over geologic time, Russell noted that there had been a steady increase in the encephalization quotient or EQ (the relative brain weight when compared to other species with the same body weight) among the dinosaurs.

The size of their brain relative to their body is much less than that of mammals, the encephalization quotient being about one tenth of that of mammals, though larger reptiles can show more complex brain development.

Different people are at liberty to come up with different methods of doing the calculations, but probably the most authoritative index is the 'encephalization quotient' or EQ used by Harry Jerison, a leading American authority on brain history.

Like other members of the genus Caluromys, the bare-tailed woolly opossum is a strongly arboreal species of marsupial, differing from other didelphid opossums in having a comparatively large encephalization quotient and smaller litter size.

Encephalization Quotient (EQ), or encephalization level is a measure of relative brain size defined as the ratio between actual brain mass and predicted brain mass for an animal of a given size, which is hypothesized to be a rough estimate of the intelligence of the animal.
