Eye-Brain Maps

The brain is a biological computer of immense complexity comprising highly specialized neurons and neural circuits. Such neurons are interconnected with high precision in many regions of the brain, if not in all. How is this precision or “specificity” achieved? There are also many observations which indicate that there is also considerable “plasticity.” How does this work? Both specificity and plasticity are found in the development and regeneration of eye-brain connections in vertebrates, and in skin-brain connections in primates.
