Number of neurons in the brain of animals

The number of neurons in animals – Top 10

It is estimated that the human brain, with a mass of one and a half kilograms, consists of almost 90 billion neurons, but does man have the largest number of neurons in the brain? It turns out that it is not the man who has the largest number of neurons, but the elephant. Man in turn has the largest number of neurons in the cerebral cortex (10–20 billion neurons). Below we present a table containing over 100 animals with the largest and lowest number of neurons in the brain.
