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 ...
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 ...
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.
Elephants are among the smartest, largest animals on the planet. With all that size and brain power, it should come as no surprise that making a baby elephant is no easy task. In fact, elephants ...
The RGB color model, therefore, is a convenient means for representing color but is not directly based on the types of cones in the human eye. The peak response of human cone cells varies, even among individuals with so-called normal color vision; [8] in some non-human species this polymorphic variation is even greater, and it may well be adaptive.

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.
