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 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 ...
Brain of a human (left), compared to that of a black rhinoceros (center) and a common dolphin (right). Elephant brains also show a complexity similar to dolphin brains, and are also more convoluted than that of humans, [20] and with a cortex thicker than that of cetaceans. [21]

In decades of studying the brains of humans, African elephants, humpback whales and other large mammals, I’ve noted the organ’s great sensitivity to the environment, including serious impacts ...
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. [79] It is the largest of all terrestrial mammals. [80] 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.
When looking at an African elephant and an Asian elephant side-by-side, you can really tell the differences in their head shapes and tasks. African elephants generally have much larger tusks than ...
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]
