The following are two lists of animals ordered by the size of their nervous system. The first list shows number of neurons in their entire nervous system. The second list shows the number of neurons in the structure that has been found to be representative of animal intelligence. [1] The human brain contains 86 billion neurons, with 16 billion ...
Thus, large whales have very small brains compared to their weight, and small rodents like mice have a relatively large brain, giving a brain-to-body mass ratio similar to humans. [4] One explanation could be that as an animal's brain gets larger, the size of the neural cells remains the same, and more nerve cells will cause the brain to ...
The domestic cat is attributed a value of between 1 and 1.71 (for comparison: human values range between 7.44 and 7.8). [1] [3] The largest brains in the family Felidae are those of the tigers in Java and Bali. [5] It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates. Most experiments ...

Birman. Birmans strike a balance between medium and large, with males weighing about 10 to 15 pounds and females ranging from 6 to 10 pounds. Their fur is medium-length and silky to the touch.
Encephalization quotient. Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species. [1][2] It has been used as a proxy for ...
A standard measure for assessing an animal's brain size compared to what would be expected from its body size is known as the encephalization quotient. The encephalization quotient for humans is between 7.4-7.8. [60] When the mammalian brain increases in size, not all parts increase at the same rate. [61]
