"For much of the 20th century, the size of the brain was regarded as being of primary importance in determining an animal’s intelligence. The brain of a raven, by the way, is roughly the equivalent of a large Brazil nut (15.4g compared to an average body weight of about 1kg). However, recent studies have challenged this traditional theory and shown that, in fact, it is the density of neurons packed into a brain that is the true marker of intelligence. Judged by this criterion, the raven has been shown to possess 1.204 billion neurons in its forebrain (the avian equivalent of the cerebral cortex which is the nucleus of human intelligence) a far higher concentration compared with primates, or other mammals and birds."
