{"fact":"Despite not having a neocortex like mammals, crow brains are packed with neurons, especially in the forebrain, sometimes even exceeding those of some primates.","context":"It turned out that they are approximately equal in mass, and the density of neurons for the birds of Corvidae family (the Crows) in the corresponding areas of the brain is much higher. In addition, it has been proven that the number of neurons in the forebrain of Corvidae family birds is equal to or even greater than in primates’ forebrain (night monkeys and capuchins), whose brains are almost four times larger.","source":"Elena Prelikova; Nikita Kukshin; Maxim Kopylov; Dmitry Nekrasov, Development of automatic exchangers of small garbage for bird-seed and training of Corvidae family birds (the Crow family) to collect small rubbish, 10.1051/e3sconf/202341102006","index":488}
