About 75 percent of cases have been able to predict true life expectancy.
Experts from the American Vanderbilt University came to the conclusion that the number of neurons in the brain depends on the average life expectancy of animals and humans.
Brazilian neuroscientist Suzana Herculano-Houzel examined data on life expectancy more than 700 species of warm-blooded animals using the AnAge database. She then analyzed the number of cortical neurons from various representatives of the animal environment. She then compared those ratios.
For example, birds live about ten times longer than mammals with the same parameters of the body, but fewer neurons in the brain. Previously, scientists had paid more attention to the study of body weight and metabolism, however, not more than 30 percent of the predictions came true.
Herculano-Houzel added that people considered separately, noting the long period of childhood and post-menopause. Research has shown that people live on average the same as animals, having a similar number of cortical neurons.
