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]
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 ...
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]
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 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.
