This type of communication also makes it difficult to change subjects or to go into detail about a subject without the use of verbal indication. Body-to-body communication is only helpful
Brain-to-body mass ratio 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. 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 increase in size to a lesser degree than the rest of the body. This phenomenon can be described by an equation of the form E = CS, where "E" and "S" are brain and body weights, "r" a constant that depends on animal family
