However, the cerebral cortex, which is the major center of cognition, has only about one-third of the number of neurons as a human's cerebral cortex. [5] While elephant brains look similar to those of humans and other mammals and has the same functional areas, there are certain unique structural differences. [6]
The brain of an elephant weighs 4.5–5.5 kg (10–12 lb) compared to 1.6 kg (4 lb) for a human brain. [77] It is the largest of all terrestrial mammals. [78] While the elephant brain is larger overall, it is proportionally smaller than the human brain. At birth, an elephant's brain already weighs 30–40% of its adult weight.
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
Elephant brains are structured similarly to human brains, which means they are capable of a wide variety of intellectual abilities, including memory, grief, mimicry, art, playing, using tools ...
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus ' little man, miniature human ' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or sensory functions, for different parts of the body.

Skeleton of Jumbo, a young African bush elephant bull, compared to a human. The African bush elephant is the largest terrestrial animal. Under optimal conditions where individuals are capable of reaching full growth potential, mature fully grown females are 2.47–2.73 m (8 ft 1 in – 8 ft 11 in) tall at the shoulder and weigh 2,600–3,500 kg ...
Brain size usually increases with body size in animals (i.e. large animals usually have larger brains than smaller animals); [4] the relationship is not, however, linear. Small mammals such as mice may have a brain/body ratio similar to humans, while elephants have a comparatively lower brain/body ratio. [4] [5]
