The number of synapses grows in the childhood and adolescent period of a person’s life and affects the intellect.

More Interesting Facts About The Human Brain

The largest female brain in weight is 1565 g. The record weight of the male brain is 2049. The brain of I. S. Turgenev weighed in 2012 the average weight of the male brain was 1372 Flyweight normal neatrofirovannogo brain belonged to a 31-year-old woman – 1096 dinosaurs up to 9 meters in length, had a brain the size of a walnut and weighing only ’70
