Here, a decussation refers to the crossing of millions of axons. To achieve this, there needs to be a tight control in order to have as few errors as possible. The advantage of having such a complicated system may be to compensate for the 180 degree inversion in visual perception through the eye. In addition, it may provide a more robust structure.
