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 the sperm whale, considered the largest brain in the world. Sperm whales have the largest brain mass of any animal on Earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males. [23] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [24]
Scientists suggest special blood vessels in the animals’ brains may protect them from pulses in their blood that would damage the brain. Study sheds light on why whales do not get brain damage ...
