Proportion flocculi of pterosaurs in the brain reached 7.5%, and average only 1-2% of vertebrate flocculi in his brain. This causes the vision Flocculi pterosaurs became much better. But a large proportion of this is caused by a wide expanse of wings, because in addition associated with the eye muscles, flocculi are also working closely with the sensory nerves.
