The hippocampus of an elephant takes up about 0.7% of the central structures of the brain, comparable to 0.5% for humans and with 0.1% in Risso's dolphins and 0.05% in bottlenose dolphins. [ 17 ] The hippocampus is linked to emotion through the processing of certain types of memory , especially spatial.
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 ...
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] It is generally agreed that the growth of the neocortex , both absolutely and relative to the rest of the brain, during human evolution, has been responsible for the ...
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.
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 ...

Elephants that live in zoos, however, have a much shorter lifespan, and things like lack of exercise, stress, and certain health issues, such as obesity or joint problems, all contribute to this.
Von Economo neurons are relatively large cells that may allow rapid communication across the relatively large brains of great apes, elephants, and cetaceans.Although rare in comparison to other neurons, von Economo neurons are abundant, and comparatively large, in humans; they are however three times as abundant in cetaceans.
