The above is interesting because it highlights the fact that humans do not have truly unique cognitive abilities, and hence must differ from other animals not qualitatively, but rather in the combination and extent of abilities such as theory of mind, imitation and social cognition. Moreover, viewing the human brain as a linearly scaled-up primate brain in its cellular composition does not diminish the role that particular neuroanatomical arrangements may play in human cognition. Rather, such arrangements should contribute to brain function in combination with the large number of neurons in the human brain.
